I Worked at STAC during the period where the Stacker software was taking off. Yes, it was outright theft, and the writing was on the wall early on. Microsoft would lose the lawsuit but win the war so they made a settlement offer that STAC could not refuse. In the end several executives at STAC came out of it quite rich, but the software side of the company was doomed. Fun little fact: the core product was itself based on the LZ-77 compression algorithm and had a minimal TSR hooked into the disk I/O interrupt. Apart from the 4k sliding buffer needs, not much memory was needed once the TSR was loaded up and hooked in. The funny part is all the people who thought they could double their disk space when most of their files were already compressed archives, which often required even more space because of differing compression algorithms.

I have to agree with "I am using a computer" Patent Infringement isn't theft especially software based ones where as the video noted was very common and not as novel as STAC was trying to convey.
As a computer service tech in that era, I absolutely hated Stacker and Doublespace. So many times I had customers lose data when the archive file went corrupt. Once in a great while, we could recover it, but that was rare. One sector going bad on the hard disk could wipe all your data at once instead of just one file.
@@christoffer4862 I'd guess OP understands: archiving != backup. To fight your side, he didn't say corrupt... though I do infer that from his comment. I expect the corruption was likely due to the same as nearly all corruption / read issues I recall from that era; limited knowledge of the system hardware, combined with fewer api (as it's called now) routes/less access to system level data, e.g. dynamic hd space data was only added in 98 I believe. I remember VBscripting for 95, and having to poll every time...
Oh, no, you just revived an old trauma and its scars buried deep in my brain. I was the victim of the silent, hidden corruption that happened sometimes when the drives were full or near full. Never used disk compression software again. But yes, I do remember it making the computer slightly faster because of lowered disk access.
I used to use Stacker! It was an impressive piece of software! Now that I work as a developer, I can fully appreciate just how awesome it was. Love these kinds of vids! Cheers
Growing up a computer-freak in the 70's and 80's I remember this story first hand, and still think it's as crazy today as it was back then. In the early years of the "modern" computer era everyone was stealing everything from everyone else. And that is the single main reason we all managed to go so far with programming so quickly. New software was being developed and released at such an incredible rate that the idea anyone could "own" something such as "disk compression", (or how to engineer a program that would compress a disk), was, just like the concept of a GUI, ridiculous. No one programmer or group of programmers thought up or developed all these different features and software packages - everyone was running full-out building off of, (and on top of), everything that had come before. Some time in the 80's a programmer friend showed our computer club a disk compression program he had written for BASIC of all things. It was simple, and buggy, and amazing all at the same time... Too bad the judges and all the lawyers had no idea about how the things they were fighting over in the courts really worked.
Yeah, I still find it amusing that Bill Gates wrote a scathing letter to the Homebrew Computer Club in which he flatly stated "You steal your software" after finding out that they'd ... ahem ... *acquired* copies of Microsoft's Altair BASIC interpreter (bugs & all) w/o paying anything ...only to later get hauled into court when it was discovered that Microsoft had outright stolen code from Apple's QuickTime software & brazenly incorporated it into its competing software @ the time -- Microsoft Video for Windows. Oh, the irony....

I remember activating dblspace on my parents PC back in the early nineties. I, an almost teenager, was sweating into the late hours, wondering if I'd make a big mistake-but-it worked---but I ultimately chickened out and removed and undid the compression. Parents woke in the morning, none the wiser :)
Once, back when I was a kid and hard drives were measured in megabytes, I was looking for files to delete because, despite using doublespace (or was it superstor? or drivespace, possibly... I can't really recall), I didn't have enough space for something or other... I was ecstatic when I found a _massive_ hidden file which didn't seem to belong to any program... I wasn't as happy once I lost all my data and had to reinstall everything after deleting it, though... 😓
Well, considering both Steve Jobs AND Bill Gates both "borrowed" the concept for having a window-based graphical user interface from visiting Xerox back in the day and seeing what Xerox had already built and were using internally... yea, I wouldn't doubt it if he "borrowed" disk compression from somewhere else too, lol.
Wow, really? I never heard that before. Thanks for sharing your amazing insight and story telling with the world, now everyone will know about this previously undiscovered information.
The original patent has a problem in that is has the phrase " including circuit means operable " in the one and only independent patent claim. This restricts the patent to implementation in hardware due to the circuit citation. "means for" language in the only independent claim may lead to other restrictions. Although the fact the software implementation runs in the computer could be called a "circuit" , however I believe the spirit of the original patent was to protect the IP relating to the hardware based card that was the original product. I am surprised Microsoft lost, however the courts are more knowledgeable of software and hardware now.
Did they steal? No, but they weren't angels, either. Then they paid up ONLY after getting caught. Great video! I remember those days and being confused by the various names for compression schemes.

I remember getting a pirated copy of stacker in the early 90s and somehow making my hard drive unusable, had to low level format it to get it working again. Good old days. Thanks for bringing it up.
Watford electronics had a type of "on the fly" disk compression on the ADFS system for the BBC micro back in 1982. if I remember it compressed at a ratio of 1.77/1 and still could handle normal disks including the very finicky disk version of elite.
Holy crap I remember "doubling my diskspace" in the old days. It worked to an extend, but completely screwed up the available space indicator. There was also some practical issues that made it a headache to use, I can't remember if it was corrupting data or destroying the disk.
It didn't really screw up the available space indicator. You can never predict with certainty how much free space you have on a compressed disk. The problem is, your available space depends on what the compression ratio will be of data that you haven't written to it yet. The thing can't predict the future. So they just guessed that you'd get 2:1 compression, and doubled however much actual free space you had. Whether you got that or not depended on what kind of data you eventually actually wrote to it. It's like asking someone how much data you can put into a 1GB zip file. That depends entirely on what kind of data you put in it.
Microsoft was extremely sleazy in the early 90's. WordPerfect was THE word processing software. It ran on DOS up to ver. 5.1 Almost every law office had it because you could create templates and macros to automate the legal documents. In fact, you can still find It running in some law offices today. It is so flexible It can run on an IBM XT with just a couple of MB of RAM right up to the most modern device today. You just need to patch it for x64. WordPerfect 6.0 was the first Windows based edition. It didn't do anything but crash. It was unusable. MS did something to Windows to prevent it from running properly. They bankrupted WordPerfect because they wanted Word to become the new standard. MS really was a truly evil company until the US government reigned them in with an abti-trust lawsuit.
I remember running Stacker back in the day. couldn't do images very well, but anything else it worked great on. Also people might have warm fuzzies for Microsoft these days, but those of us that dealt with them in the 90s know better.
I remember trying the double space option combined with Windows 3, it did not work well. Scandisk is oddly nostalgic to see again. Interesting and Great video.
friends 486 laptop with a whopping 80mb hard drive installing with drive compression taking about 3 hours, think compression was the only way to get enough drive space to make the install fit! #goodtimes
I remember that nightmarish double space/Stacker software and I can't tell you how many drives were toast because of it. People lost tons of data because of it and I always recommended to my clients to NEVER use that software. But, I would inevitably get the call from some old goat who thought he found the fountain of youth and before I could say NOOOOOOOO it was too late lololololo

Without it he would be incarnated, India, where the Bill & Melinda Gates Foundation and their vaccine empire are under fire, including a pending lawsuit currently being investigated by the India Supreme Court. Narayana Kumar of The Economic Times of India has just written a scathing report of fraud and scandals surrounding the Gates vaccine empire: Controversial vaccine studies: Why is Bill & Melinda Gates Foundation under fire from critics in India? Kumar starts out his 4 page article by focusing on the current case before the India Supreme Court regarding deaths and injuries occurring during drug trials carried out over Merck’s HPV vaccine Gardasil. Vaccine trials were conducted on thousands of girls between the ages of 9 and 15. Many of the girls fell ill, and at least 7 died, and the lawsuit is alleging that in most of these cases, the girls and their parents did not even know what kind of vaccine trial they were participating in.
I hated disk compression as hard drives were very fragile at the time and thrashing them to an early death did not seem to be worth the "savings" they offered up front. Take any hard drive from the "glory days" and those that still work likely had not been subject to the hell of disk compression. Proof? Load any type of disk compression utility on an older computer and watch that hdd light flash faster than a strobe light at a disco.
I do not recall the details since I was young and it is decades ago. But I still recall the Memo to myself to "never use any Type of disk doubler again". It was not worth the problems that it was creating.
Yeah. I was certain MS had actually stolen Stac Electronics software. I thought they had entered into a partnership, then MS dissolved it, taking what they stole from Stac.
Quick search found grantster.com/2012/06/07/the-stacker-conspiracy/. One commentor claims he worked for Stac, and he claims a comparison of source code was done, and it contained Stac copyrights within it. I'd heard this too, back in the 90s. Either the commentor is lying, having heard the same rumors I had over 20 years ago, or he's legitimate.
I knew Gary Clow during those days and an interesting twist was that Art Collmeyer a Stac board member received Microsoft and the board hadn't really discussed what they wanted from Microsoft, so he "threw out" the 43x $1M/month and the $39.9M investment. He didn't think MS would accept but they just said "OK"! Art was on the board of a company I ran called Syntricity.
This is Microsoft at its essence. I was around when this happened, and got off the Microsoft train as soon as I was able (Linux). I've told people for years that Microsoft is a very evil corporation, but they don't listen or don't care. Apple's damn near as bad, but in a different way.

Great video! I was always curious about disk compression, but even today I don't use it because I know it takes a toll, however small, on performance. Plus, especially now, the large share of my disk space is taken up by already-compressed data that would not benefit at all, and might even be increased in size, by any attempts at further compression. I paid a lot of attention to tech news at the time all this was happening, but with this mostly being pre-Internet stuff, my ability to do so was pretty limited as a teen. I do remember a very excellent summary of how Huffman compression worked being in Computer Shopper one time, though. I tore it out and kept it in my wallet for years. Data compression has always been a very interesting topic to me, and I still read about it from time to time and intend to implement fractal compression now that its patents are all expired when I get around to it for video to play with, so this video was right up my alley!

I bought the MSDOS 6.22 upgrade, which at the time meant all you had to buy was any computer part, and you qualified for the upgrade. I bought a parallel printer cable, as that was the cheapest part they had in stock. I had no printer at the time, but the cable was useful as a source of hook up wire.
I remember optimizing PCs in those times, I rarely enabled dblspace and drvspace on customer computers, as most of them were business machines that couldn't afford the loss. I also remember that I did experience loss of file performance to a degree that once I had enough HD space to live without compression, I removed it. I also remember 6.22 as the absolute best version of DOS before Windows 95 and became quite adept at optimizing load order of drivers into Upper Memory Blocks.
As pointed out in the video, there was a period where using Stacker was _faster_ than not. CPUs were getting faster rapidly, while consumer-grade drives were still dog slow. Decompressing was easily faster than reading. I remember using SCSI drives at home, at least for the main system drive, because they were faster. IIRC, I'm taking 5 Mbytes/second. The speed was limited by the arial density and rotation rate, and started to climb as hard drives got larger: more bytes going past the head in the same 1 revolution. I recall that was still true for Windows 3.1 machines running on 486 CPUs, up to the time DOS 6 came out including their own DBLSPACE.
Thanks for these videos I love them. I was very much into computers back in these early days but too young to care/follow all these details. Now I find it fascinating to learn what was going on behind the scenes! Keep up the good work :D

I wrote about this on my blog many years ago. To my amazement, someone who (purportedly) worked for Stac wrote a response. I don't think they got all of the facts right, but it was interesting to see. I've added the response just in case anyone is interested. I worked for STAC Electronics during the time of the Microsoft lawsuit. The software engineers at STAC Electronics showed a bunch of us employees the source code from both DoubleSpace and Stacker 1.0 side-by-side. They were identical. Microsoft didn’t even bother to remove the STAC Electronics Copyright notices embedded into the source code.

Though I'm not the biggest fan of Microsoft's business practices, it's complete BS that STAC won that lawsuit, at least based on the information given in this video.
Yea, they ruled against MS because they saw them as bullying during the trial. Instead of fighting the patent saying "that was for a hardware card" or saying, "OK, we'll change the implementation slightly so it follows this 1979 paper published in the ACM instead" they just said "we're expensive laywers and we'll play that game". BTW, wasn't there also a plagiarism claim involved too, where some of stac's code appeared to be present?
@@JohnDlugosz it was more than just the hardware card though, the software code was also explicitly licensed by the original author, and they demonstrated commercial precedent along with the licensing. The patent was mostly to demonstrate the link between the algorithm and the hardware which was later implemented in software. Too complex for me to fully understand, but chunks of the actual stacker code were found in the Microsoft product, meaning that their purchase of the competitor software was not a full answer to the infringement claim. Sure, the bullying was likely to be the final straw, but there was substance to the claim.
While searching the web about hard drive history, I was surprised that the first hard drive to break the 1GB barrier was created as early as 1980. Though by no means portable, it was one of those industrial size things (cabinet and drive weighed about 550lbs / 250kg total, that's freaking titanic!) That was interesting to discover. Also to realize that within several decades, we've gone from 10MB hard drives to 10+ TB hard drives. Another web search led me to the current largest drive available being 16TB in size. Technology never ceases to amaze me.
Living through those days was even more amazing... "My" first computer, (that I paid for myself), had a 100MB hdd... then I bought a computer that had a 320MB drive that lasted me for years, until my then g/f bought me a 5GB drive as a gift. I had zero idea what I would use 5GB for - it seemed like an impossible amount of space to fill. Today, my main computer has 8 drives, combined total storage just under 15TB, and I'm running out of room... again...
Closing remarks on WIndows 10: The compression built-in to NTFS (almost from the beginning, making it contemporary with the events of the story long before NT became just "Windows") is not as good at compressing, I noted at the time. There's also an issue with how NTFS manages sectors in groups of 16 I discovered later, meaning that files tended to leave gaps of unused space after them, and defragmenting did the same thing! My own efforts to remove these "interstices" pointed to an effect where after writing to a span of sectors (such as by the defragmentor) the following sectors (rounded up to a multiple of 16) remained locked for some time so that the next file-relocation issued by the defragmentor would have to skip them. This is in contrast to one of the features of DBLSPACE, which was to _eliminate_ cluster-size bloating. (In FAT, files are tracked in allocation units much larger than a sector, and increasing this was a way to cope with larger disks leading up to FAT32.)

My absolute favourite version of Dos 6 was v6.21 which is the one that never went into retail but was supplied to OEMs and which I got when working at Amstrad in the 90s. It was produced because of the double space fiasco and had that all ripped out of it. It was the best version for all the latest enhancements of dos but also the most amount of base memory for dos games 😂 which I still had copies of it now just for nostalgia purposes.
I've been enjoying these walks down memory lane. Back in those days you really had to know your computer. If your computer started having problems you couldn't just go to the internet for help. You either knew somebody or you were that somebody to fix the problem.
Very well researched! (Now I don't have to cover the history when I go into compression hardware products such as Stacker XT/8, AT/16, Expanz! and ddtrans)
I don't recall anyone thinking Stacker made drives faster back in the day. Before I installed it, everyone I knew warned me that it would make my drive slower. Once I started using it I didn't really notice a difference in disk speed either way. However, I disliked the way the size of the drive / amount of free space would change constantly based on compression quality (making it hard to estimate if I had room to install things), and ultimately ended up removing it and using ZIP to compress stuff that I wasn't using.
It was true. Long story but we had a big need (in multiples) and tested before committing. Mid 486 era, just after the the DX-4 came out. Overnight clock speed tripled on the same (usually) platform, but HD speeds and buses, already behind, were now absolutely the choke point. It was faster to use all that DX4 goodness to compress and decompress on the processor side of the the small orifice the HD system represented. Didn't last long. 4-5 years?
Yeah, it was quite easy to corrupt your whole disk. But we took the chance a lot of the time because hard drives were so expensive. I found a receipt for a 240 MB (not GB) drive not long ago it was $200. You could buy a crappy but driveable used car for that price back then.

I agree, though unfortunately all the early compression algorithms were patented. I think gzip was the first open compression algorithm. Thankfully personal computing is sufficiently old that all of the important features are no longer patentable.

SCANDISK was the nightmare...one red B would turn to two, and tey would multiply like the game of Life until the disk ground to a halt.
I used Stacker for a while but you had to be careful. A friend managed to configure it to compress the OS. Which was fine but when his drive crashed he couldn't recover any of the data. Never trusted any of the other offerings and certainly not something "bundled" with MSDOS. We still remembered the buggy mess that was MSDOS 4.

The fact STAC basically waited till after Microsoft signed on with the competitors product to go after them legally; bespeaks of sour lemons. This one is not like some of the other Microsoft issues.
You made me nostalgic! I was there. To some part.... with the early disk compresion on DOS. I shifted my production to Windows NT early in 1993. Yes, you read correctly. But that is another story. Curious I am, (Yoda) what disk compression was used in Windows NT. I have over the years used it in 1000th of systems including mission critical servers. At best, like with Ansys matrix files (they can be HUGE) the compression factor is 90%. With a jpg - forget it!! Oh, I met Gates in Stockholm early 1994. Thanks for a highly interesting episode!!!!!!!!!!!!
Not true. PKWare did start with PKARC. It was some five times faster than the Arc by Sea but apparently had copied some code from Arc. This resulted in a lawsuit in which PKWare agreed not to create Arc compatible software. They chose to create a new far better format: ZIP and PKZip/PKUnzip to handle it. At the time I had an 8088 PC. I saw Arc as interesting concept but with no use because of its slowness. PKArc changed all this. Like most my sympathies were on the side of PKWare (though Sea likely was right in the case). As a result I paid $47 for the PKZip.
@@okaro6595 Paul Katz even copied the spelling errors in arcs source. My impression is that calling it "some code" is quite the understatement. Arc were extensively used in the fidonet community to compress data before long distance calling.

Yeah I remember all those disk compression programs. The big winners of that time were tape drive manufacturers. If you didn't have a compressed drive, a corrupted file was easy to restore from a floppy backup, but if your compressed drive went kerplooey, you had to restore the entire drive whether you liked it or not. And that happened pretty often. We've come a long way since then.
This is one of those cases where I'm firmly on Microsoft's side, partly because I dislike software patents and partly because this was a clear abuse of related but not similar technology and a patent of something Stac obviously had not come up with only by themselves.
I knew the rough outlines of the whole dblspace and DOS 6.22 but it was great to get all the details and corporate wrangling. It was the DOS 6 to 6.22 problems and a crashed disk that opened my eyes to what kind of company MS was. 1992-94 a tough time to grow up in the PC world.
I remember laughing my ass off the day I read Stac had gone under for good... They should have made a deal with Microsoft, maybe they would have lasted a bit longer before failing utterly.
I do recall being struck by the DBLSPACE disk corruption in the 90s. So many files lost and no internet to know how to recover them. This taught me the hard way to backup more frequently, and to stay away from any automatic disk compression solutions forever after.
Ah the memories :-), I used stacker 4.0 on my pc of the time, it had 300MB and with stacker it was (almost) double, only thing was, it could take all night for it to defrag the harddrive, I would lie in my bed listening to the sounds of the harddrive working until I eventually fell asleep 😁
We had Stacker on our 386 PC that only had a 60MB hard drive. It worked great. The only issue was the fact that it was a TSR program that took up precious memory.
Thanks for this. I recall using MS-DOS 5.0 and Stacker successfully together for several years in the early 1990's with my trusty Leading Edge 286 that had shipped with a 30mb HDD.
I used to use DoubleSpace myself back in the old days on my HP 386 DX20. Seem to remember i had a 20mb HDD. But the performance hit of using doublespace was huge on a little cpu...
Nice history lesson, thanks for bringing up those memories. But with the advent of Windows 95 and the ever increasing hard drive sizes, Microsoft should have phased out the disk compression. But no, even in Win10 you can tick the box "Compress this drive to save disk space" which does absolutely nothing, except slow down the system, because most of the files today can't even be compressed anymore. I had dozens of clients over the past decades who thought it would be smart to use this option only to find out that their systems became unusable. Great stuff, Microsoft.
I seem to remember some PCs in the UK being advertised with Mahoosive hard drives, while the fact that compression had to be used was in MUCH smaller print!.
This was a fantastic video, I was always confused about the Doublespace vs Drivespace utilities. Also wondering what was the deal with MS DOS 6.22 being more popular.
Thank you! for mentioning DR DOS 6.0. I believe it shipped around the same time as MS DOS 5.0 and was streets ahead. I convinced my father to buy it to run on his IBM PS/2 and we found it a great OS with many advantages over MS DOS 5.0. Of course, MS was its usual bully self, seeing others' good ideas, copying them, and then crushing them.
What I found most commonly turned out to be the case was whenever upgrading to a bigger hard drive, that it was far easier and simpler for me to buy a much bigger drive capacity and soon I ended up with disk drives in the high gigabyte range. If you buy a 700GB drive you get most of that as usable space after formatting is complete. Some older versions of Windows actually were a little shaky on disk sizes over a certain limit and would either create multiple partitions or be unable to reach the latter portion of space out of addressing reach. Newer versions did of course fix this but one could never have enough disk space it would seem! :D
Every hardware and software combination has disk/partition/file size limitations. We ran into this numerous times over the years, and it still happens today.
Bill "Stole" a lot of software. He initially either bought you out, or licensed the software and then bought you out, or had it long enough to make a derivative. He was definitely a business man, more than a computer genius or guru.
MSDos was stolen in the first place. IBM wanted to use CP/M but couldn't get in touch with Gary Kildall, it's creator, so they showed it to Microsoft and said "We want something like this". All Microsoft did was to steal CP/M, rename a few commands, then ship it as MSDos. Gary Kildall did eventually get a payout from Microsoft (a mere $50,000) by way of "recognition" but it was way too little and way too late.
@@Kevin-mx1vi Bullshit. Did you just make that nonsense up, or did you read those lies somewhere online? IBM didn't "want" CP/M, it was Gates who sent them TO Kildall and Digital Research, to check out CP/M, at the SUGGESTION of Bill Gates. This is historical fact. Microsoft and Gates were already working FOR IBM - writing a BASIC interpreter for the upcoming IBM PC. But Kildall, being Kildall, screwed up making the deal, (and there are multiple stories of how), and lost the chance to become Bill Gates. So IBM went back to Microsoft, and Gates, being Gates, (smart), sensed opportunity and didn't screw up. Microsoft BOUGHT the rights to 86-DOS, (QDOS), from SCP, (for a "mere" $50,000), modified the code to meet the IBM specs, (which made the new "MS-DOS" far better than anything CP/M had to offer at the time), and the rest is history. Microsoft never paid Kildall a dime - there was no reason to, they didn't owe him anything, and he didn't deserve anything.
Those were the days I remember using dos 5.0 with stacker 2.0 for a long while until eventually moving to dos 6.22. The whole reason for using drive space doubling technology was Falcon 3.0 at the time I had a 210mb drive
Interesting, it quite explains the accident I had in 1995 with DoubleSpace. I can't recall if I had MS-DOS 6.2 or prior - but seeing this I presume it was pre 6.2 - certainly something went very bad one day. It began with a crash, and I had to reboot. Then NDD found thousands of "lost chains" and I lost a large amount of data. It all ended with a format and I never returned to DoubleSpace nor did I ever try DriveSpace (Win '95 was far too heavy for my old computer).
Loved it! Great video and I remember all this when it happened. There was a shareware program called Diet that "kinda" did the same thing before too, it would work on the file level and intercept read and write commands using a TSR
nice to know the pass... cuz many of us come after these events and would be nice to know the history of somethings....... keep it up ... goood job bro....
Those were the days! My fresh-faced and eager young self had talked a few good-sized law firms and another couple CPA firms into allowing me to be in charge of their IT needs. I was excited as it looked as though my future was set. Indeed, it was set alright. DoubleSpace was but the first of many curses that would plague me over the next twenty years and have me sleeping under desks on office floors rather than my bed most nights. I look back on it now with a bit of nostalgia, a badge of honor even, but I lived in a state of constant hyper vigilance and dread in the knowledge I was only one bad backup or crummy software update away from the combined and focused hostility of a hundred attorneys and their savage secretaries!
I tried using the DOS double space and drive space, never had a lot of luck with them. They seemed to slow everything down way to much for my taste, I was one of those idiots who was always searching for faster operation of my computer! I have recently given up on such a search when my wife, last year before Christmas told me she was giving me 500 bucks to buy a new laptop. She said I knew more about what I wanted, and she felt guilty for causing me to spill coffee on my Macbook Pro when she grabbed my arm as I slept in my recliner, a full cup of coffee in my hand and my Macbook on my lap. So I shopped around for days seeking the fastest machine I could find for 500 bucks. At long last I settled on a new HP laptop, the specs were fantastic although the screen was a bit small compared to the desktop replacement machine I had been running. Man when that machine got here, it was Amazing! I am still using it as I type and it still is fast as hell. It boots in seconds to either Win 10 or Linux Mint that I use as my main OS most of the time. She does everything I ask and never blinks. That said I don't think I would use double space on it if I wanted more space, I would probably buy a new hard drive, or, perhaps get rid of a bunch of movies I don't need to store on it.

I Worked at STAC during the period where the Stacker software was taking off. Yes, it was outright theft, and the writing was on the wall early on. Microsoft would lose the lawsuit but win the war so they made a settlement offer that STAC could not refuse. In the end several executives at STAC came out of it quite rich, but the software side of the company was doomed. Fun little fact: the core product was itself based on the LZ-77 compression algorithm and had a minimal TSR hooked into the disk I/O interrupt. Apart from the 4k sliding buffer needs, not much memory was needed once the TSR was loaded up and hooked in.
The funny part is all the people who thought they could double their disk space when most of their files were already compressed archives, which often required even more space because of differing compression algorithms.

As a computer service tech in that era, I absolutely hated Stacker and Doublespace. So many times I had customers lose data when the archive file went corrupt. Once in a great while, we could recover it, but that was rare.
One sector going bad on the hard disk could wipe all your data at once instead of just one file.
Compression does not replace backups...
I am positive any lost data would have disappeared anyway without compression.
@@christoffer4862 I'd guess OP understands: archiving != backup. To fight your side, he didn't say corrupt... though I do infer that from his comment. I expect the corruption was likely due to the same as nearly all corruption / read issues I recall from that era; limited knowledge of the system hardware, combined with fewer api (as it's called now) routes/less access to system level data, e.g. dynamic hd space data was only added in 98 I believe. I remember VBscripting for 95, and having to poll every time...
Wrong. One bad sector affects one file.
If it was in root dir - it would be the same even without stacker/doublespace.
@r4rev2 wrong
False memories.

Oh, no, you just revived an old trauma and its scars buried deep in my brain. I was the victim of the silent, hidden corruption that happened sometimes when the drives were full or near full. Never used disk compression software again. But yes, I do remember it making the computer slightly faster because of lowered disk access.
im scarred for life too
Same here. Never forget. Never again.

Growing up a computer-freak in the 70's and 80's I remember this story first hand, and still think it's as crazy today as it was back then. In the early years of the "modern" computer era everyone was stealing everything from everyone else. And that is the single main reason we all managed to go so far with programming so quickly. New software was being developed and released at such an incredible rate that the idea anyone could "own" something such as "disk compression", (or how to engineer a program that would compress a disk), was, just like the concept of a GUI, ridiculous. No one programmer or group of programmers thought up or developed all these different features and software packages - everyone was running full-out building off of, (and on top of), everything that had come before. Some time in the 80's a programmer friend showed our computer club a disk compression program he had written for BASIC of all things. It was simple, and buggy, and amazing all at the same time... Too bad the judges and all the lawyers had no idea about how the things they were fighting over in the courts really worked.
And any encryption was classified as munitions and you did NOT want to export that out of the US or the feds could go after you! Fun times!
"Did Microsoft Steal X?"

Parents woke in the morning, none the wiser :)
This wake did they change?
Once, back when I was a kid and hard drives were measured in megabytes, I was looking for files to delete because, despite using doublespace (or was it superstor? or drivespace, possibly... I can't really recall), I didn't have enough space for something or other... I was ecstatic when I found a _massive_ hidden file which didn't seem to belong to any program... I wasn't as happy once I lost all my data and had to reinstall everything after deleting it, though... 😓

The original patent has a problem in that is has the phrase " including circuit means operable " in the one and only independent patent claim. This restricts the patent to implementation in hardware due to the circuit citation. "means for" language in the only independent claim may lead to other restrictions. Although the fact the software implementation runs in the computer could be called a "circuit" , however I believe the spirit of the original patent was to protect the IP relating to the hardware based card that was the original product.

Watford electronics had a type of "on the fly" disk compression on the ADFS system for the BBC micro back in 1982. if I remember it compressed at a ratio of 1.77/1 and still could handle normal disks including the very finicky disk version of elite.
Holy crap I remember "doubling my diskspace" in the old days. It worked to an extend, but completely screwed up the available space indicator. There was also some practical issues that made it a headache to use, I can't remember if it was corrupting data or destroying the disk.
same experience
It didn't really screw up the available space indicator. You can never predict with certainty how much free space you have on a compressed disk. The problem is, your available space depends on what the compression ratio will be of data that you haven't written to it yet. The thing can't predict the future. So they just guessed that you'd get 2:1 compression, and doubled however much actual free space you had. Whether you got that or not depended on what kind of data you eventually actually wrote to it. It's like asking someone how much data you can put into a 1GB zip file. That depends entirely on what kind of data you put in it.
Microsoft was extremely sleazy in the early 90's. WordPerfect was THE word processing software. It ran on DOS up to ver. 5.1 Almost every law office had it because you could create templates and macros to automate the legal documents. In fact, you can still find It running in some law offices today. It is so flexible It can run on an IBM XT with just a couple of MB of RAM right up to the most modern device today. You just need to patch it for x64.
WordPerfect 6.0 was the first Windows based edition. It didn't do anything but crash. It was unusable. MS did something to Windows to prevent it from running properly. They bankrupted WordPerfect because they wanted Word to become the new standard.

Great video! I was always curious about disk compression, but even today I don't use it because I know it takes a toll, however small, on performance. Plus, especially now, the large share of my disk space is taken up by already-compressed data that would not benefit at all, and might even be increased in size, by any attempts at further compression. I paid a lot of attention to tech news at the time all this was happening, but with this mostly being pre-Internet stuff, my ability to do so was pretty limited as a teen. I do remember a very excellent summary of how Huffman compression worked being in Computer Shopper one time, though. I tore it out and kept it in my wallet for years. Data compression has always been a very interesting topic to me, and I still read about it from time to time and intend to implement fractal compression now that its patents are all expired when I get around to it for video to play with, so this video was right up my alley!

I bought the MSDOS 6.22 upgrade, which at the time meant all you had to buy was any computer part, and you qualified for the upgrade. I bought a parallel printer cable, as that was the cheapest part they had in stock. I had no printer at the time, but the cable was useful as a source of hook up wire.
Parallel port transfer was so fast back then.
I remember optimizing PCs in those times, I rarely enabled dblspace and drvspace on customer computers, as most of them were business machines that couldn't afford the loss. I also remember that I did experience loss of file performance to a degree that once I had enough HD space to live without compression, I removed it. I also remember 6.22 as the absolute best version of DOS before Windows 95 and became quite adept at optimizing load order of drivers into Upper Memory Blocks.
As pointed out in the video, there was a period where using Stacker was _faster_ than not. CPUs were getting faster rapidly, while consumer-grade drives were still dog slow. Decompressing was easily faster than reading. I remember using SCSI drives at home, at least for the main system drive, because they were faster. IIRC, I'm taking 5 Mbytes/second. The speed was limited by the arial density and rotation rate, and started to climb as hard drives got larger: more bytes going past the head in the same 1 revolution.
I recall that was still true for Windows 3.1 machines running on 486 CPUs, up to the time DOS 6 came out including their own DBLSPACE.
Thanks for these videos I love them. I was very much into computers back in these early days but too young to care/follow all these details. Now I find it fascinating to learn what was going on behind the scenes! Keep up the good work :D

I prefer MS-DOS 6.2 to MS-DOS 6.22 because I often get more conventional memory for DOS Games.
One PC game that required an enormous amount of conventional memory was Tornado by Digital Integration which was a PC combat flight simulator.

So?
I wrote about this on my blog many years ago. To my amazement, someone who (purportedly) worked for Stac wrote a response. I don't think they got all of the facts right, but it was interesting to see. I've added the response just in case anyone is interested.
I worked for STAC Electronics during the time of the Microsoft lawsuit. The software engineers at STAC Electronics showed a bunch of us employees the source code from both DoubleSpace and Stacker 1.0 side-by-side. They were identical. Microsoft didn’t even bother to remove the STAC Electronics Copyright notices embedded into the source code.
Is anyone surprised? I'm not.
Because no-one has ever lied on the Internet, especially the MS/Bill Gates haters, who still like to lie to each other about Gates saying, "640k is enough for anybody"...

... no-one has ever lied on the Internet, especially the MS/Bill Gates haters ... We know of many shenanigans they pulled or got by with simply because nobody was rich enough to stop them in court or elsewhere. And I'll bet a dollar against a donut there were lots of other things that slipped by because nobody had the technical expertise to know what was happening behind the scenes.
But at the time 640K was a hell of a lot of memory, and probably was sufficient for most situations.
Though I'm not the biggest fan of Microsoft's business practices, it's complete BS that STAC won that lawsuit, at least based on the information given in this video.
Yea, they ruled against MS because they saw them as bullying during the trial. Instead of fighting the patent saying "that was for a hardware card" or saying, "OK, we'll change the implementation slightly so it follows this 1979 paper published in the ACM instead" they just said "we're expensive laywers and we'll play that game".
BTW, wasn't there also a plagiarism claim involved too, where some of stac's code appeared to be present?
@@JohnDlugosz it was more than just the hardware card though, the software code was also explicitly licensed by the original author, and they demonstrated commercial precedent along with the licensing. The patent was mostly to demonstrate the link between the algorithm and the hardware which was later implemented in software. Too complex for me to fully understand, but chunks of the actual stacker code were found in the Microsoft product, meaning that their purchase of the competitor software was not a full answer to the infringement claim.
Sure, the bullying was likely to be the final straw, but there was substance to the claim.
While searching the web about hard drive history, I was surprised that the first hard drive to break the 1GB barrier was created as early as 1980. Though by no means portable, it was one of those industrial size things (cabinet and drive weighed about 550lbs / 250kg total, that's freaking titanic!) That was interesting to discover. Also to realize that within several decades, we've gone from 10MB hard drives to 10+ TB hard drives. Another web search led me to the current largest drive available being 16TB in size. Technology never ceases to amaze me.
Living through those days was even more amazing... "My" first computer, (that I paid for myself), had a 100MB hdd... then I bought a computer that had a 320MB drive that lasted me for years, until my then g/f bought me a 5GB drive as a gift. I had zero idea what I would use 5GB for - it seemed like an impossible amount of space to fill.
Today, my main computer has 8 drives, combined total storage just under 15TB, and I'm running out of room... again...
@@looneyburgmusic spoiled!, my first HD was 5 mb
I never heard about your channel and now I can't stop watching your videos. Good job mate! 🥰
Closing remarks on WIndows 10: The compression built-in to NTFS (almost from the beginning, making it contemporary with the events of the story long before NT became just "Windows") is not as good at compressing, I noted at the time. There's also an issue with how NTFS manages sectors in groups of 16 I discovered later, meaning that files tended to leave gaps of unused space after them, and defragmenting did the same thing! My own efforts to remove these "interstices" pointed to an effect where after writing to a span of sectors (such as by the defragmentor) the following sectors (rounded up to a multiple of 16) remained locked for some time so that the next file-relocation issued by the defragmentor would have to skip them. This is in contrast to one of the features of DBLSPACE, which was to _eliminate_ cluster-size bloating. (In FAT, files are tracked in allocation units much larger than a sector, and increasing this was a way to cope with larger disks leading up to FAT32.)
The real question is "Did I steal DOS from Microsoft by copying that floppy?"
The effort and research that goes into your videos Nostalgia nerd always astounds me. I love what you are doing, please keep it up. As a former IT student I honestly feel these videos should be compulsory viewing for current IT studants.
My absolute favourite version of Dos 6 was v6.21 which is the one that never went into retail but was supplied to OEMs and which I got when working at Amstrad in the 90s. It was produced because of the double space fiasco and had that all ripped out of it. It was the best version for all the latest enhancements of dos but also the most amount of base memory for dos games 😂 which I still had copies of it now just for nostalgia purposes.
6.21 was my last dos back in the day. No disk compression ment more disk space if you don't choose to compress it.
That's cool you had 6.21. I always heard about it but never knew anyone who had it. Most people had 6.20 or 6.22.
I've been enjoying these walks down memory lane. Back in those days you really had to know your computer. If your computer started having problems you couldn't just go to the internet for help. You either knew somebody or you were that somebody to fix the problem.
Very well researched! (Now I don't have to cover the history when I go into compression hardware products such as Stacker XT/8, AT/16, Expanz! and ddtrans)
I don't think you used the same algorithm to decompress video on the fly on 8088 domination. That one and 8088mph are my favourite demos ever!
@@MrSergione1978 Thanks :-) Correct, there is actually very little decompression for speed reasons.
I don't recall anyone thinking Stacker made drives faster back in the day. Before I installed it, everyone I knew warned me that it would make my drive slower. Once I started using it I didn't really notice a difference in disk speed either way. However, I disliked the way the size of the drive / amount of free space would change constantly based on compression quality (making it hard to estimate if I had room to install things), and ultimately ended up removing it and using ZIP to compress stuff that I wasn't using.
It was true. Long story but we had a big need (in multiples) and tested before committing. Mid 486 era, just after the the DX-4 came out. Overnight clock speed tripled on the same (usually) platform, but HD speeds and buses, already behind, were now absolutely the choke point. It was faster to use all that DX4 goodness to compress and decompress on the processor side of the the small orifice the HD system represented. Didn't last long. 4-5 years?
Doublespace was really buggy and not as stable as stacker.
Stacker was far from perfect either... All the big disk compression programs had issues back then...
Yeah, it was quite easy to corrupt your whole disk. But we took the chance a lot of the time because hard drives were so expensive. I found a receipt for a 240 MB (not GB) drive not long ago it was $200. You could buy a crappy but driveable used car for that price back then.
The Microsoft Store sells Doublespace. I remember that it became ZipMagic after DoubleSpace 3.

Lol, what didn't Microsoft steal
Who knows lol but I can list quite a few things that are either stolen or just clones lol
Uh...the name of the company I guess? I think at least that was a legitimately new idea.
Steve Jobs was given a tour of the Xerox labs, where he saw the first GUI operating system. He went back to work, and stole the concept, to create the Lisa and Mac OS. He tried to get Microsoft in on supporting their new OS, but Gates instead stole the idea of a GUI OS to create Windows. He actually stole a stolen idea. So much theft in the industry.
@@joshuarichardson6529 The original (Xerox tour) wasn't stolen but freely given to anyone who would listen.
@@JohnDlugosz And that just backs up the point that MS didn't steal anything about the GUI, especially from CrApple™. While CrApple™ and Jobs was busy making "pretty" computers, MS and Bill were busy making computers that actually let us get some work done.
I watched the dev do the clean room development of double space, so no, it wasn’t stolen at all. It was written from the ground up.
Data compression is mathematics. Mathematics is all open-source. You can't steal something that's open-source.
I agree, though unfortunately all the early compression algorithms were patented. I think gzip was the first open compression algorithm. Thankfully personal computing is sufficiently old that all of the important features are no longer patentable.
But you can patent a *process* and that is what an algorithm is.
I don't like it either.
@@gregorymalchuk272 gzip uses deflation, same as PKZIP.
P.K. documented "deflation" and described it openly for anyone to use, _and_ patented a specifically optimized implementation of it. That's a good distinction of the two and he was openly non-villified for that.

I got a 286 PC with MSDOS 5.0... 40MB was tough with all the games you could get on BBSes..and all that 8-bit porn... I got a package from the manufacturer (Austin PC) with MSDOS 6.0 disks, and I doublespaced my drive....and suddenly everything was slower than the usual slow! After a week I had corrupted it somehow, and had to FDISK it back to the start, without compression. SCANDISK was the nightmare...one red B would turn to two, and tey would multiply like the game of Life until the disk ground to a halt.
I used Stacker for a while but you had to be careful. A friend managed to configure it to compress the OS. Which was fine but when his drive crashed he couldn't recover any of the data. Never trusted any of the other offerings and certainly not something "bundled" with MSDOS. We still remembered the buggy mess that was MSDOS 4.
@@vespasian606 oh wow, never saw 4... went from 3.3 to 5!
Didn’t they steal everything? Started with like DOS source code or something

The more you dig, the more they seem to have stolen.
They never stole the DOS source code, the bought it fair and square for iirc like 50k US$. not their fault that it took off like it did and the original coder only got 50k.

That was good: "We came, we saw, we doubled." And we had forgotten all about it. I used to use Windows compressed folders later but dont bother anymore as storage is now enough if you zip as well as simply archive off disk to a dual raid mirrored backup device.
The fact STAC basically waited till after Microsoft signed on with the competitors product to go after them legally; bespeaks of sour lemons. This one is not like some of the other Microsoft issues.
You made me nostalgic!
I was there. To some part.... with the early disk compresion on DOS.
I shifted my production to Windows NT early in 1993. Yes, you read correctly. But that is another story.
Curious I am, (Yoda) what disk compression was used in Windows NT. I have over the years used it in 1000th of systems including mission critical servers. At best, like with Ansys matrix files (they can be HUGE) the compression factor is 90%. With a jpg - forget it!!
Oh, I met Gates in Stockholm early 1994.
Thanks for a highly interesting episode!!!!!!!!!!!!
do a story on how pkzip was a ripoff of arc, and how the fidonet community crushed arc due to.. erm, fake news :P
Omg fidonet, that takes me back to memory lane. Lovely days
Not true. PKWare did start with PKARC. It was some five times faster than the Arc by Sea but apparently had copied some code from Arc. This resulted in a lawsuit in which PKWare agreed not to create Arc compatible software. They chose to create a new far better format: ZIP and PKZip/PKUnzip to handle it.
At the time I had an 8088 PC. I saw Arc as interesting concept but with no use because of its slowness. PKArc changed all this. Like most my sympathies were on the side of PKWare (though Sea likely was right in the case). As a result I paid $47 for the PKZip.
@@okaro6595 Paul Katz even copied the spelling errors in arcs source. My impression is that calling it "some code" is quite the understatement. Arc were extensively used in the fidonet community to compress data before long distance calling.
The kind of informed, amazing tech history that made you stand out in the first place. I have a smile on my face. Thanks for the trip (and letting me know.among so many other things, where that weird but very familiar version number, DOS 6.22, came from).
I can remember when 1GB was just madness.
My first PC had a 420Mb drive. I recall being told that I'd never fill that.
We upgraded from a 120 meg drive. Needles to say, it was mind blowing having all our games available without installing from floppies, or store in an archive to save space. And that's with dual booting with Windows 95, ironically with OS/2's boot manager...
I once had a TRS-80 with a tape recorder to store files.
@@jasonuk8333 My first DOS PC had two 360K floppies, and a 20MB hard drive was $325 -- the PC itself was $1600, an optical mouse was $125. That was in 1986... (I didn't get either hard disk or mouse until much later)
Before that, my parents had an Apple //e with two floppy drives, don't remember how much they held. I still have most of my old PCs, not that first one sadly, but I do have my second one and it's in mostly running order -- a 20MHz 286 with 4MB RAM, 300MB hard drive, EGA graphics, running DOS 6.22 and Windows 1.01. The EGA monitor and Windows 1 are from my first PC...
Yeah I remember all those disk compression programs. The big winners of that time were tape drive manufacturers. If you didn't have a compressed drive, a corrupted file was easy to restore from a floppy backup, but if your compressed drive went kerplooey, you had to restore the entire drive whether you liked it or not. And that happened pretty often. We've come a long way since then.
This is one of those cases where I'm firmly on Microsoft's side, partly because I dislike software patents and partly because this was a clear abuse of related but not similar technology and a patent of something Stac obviously had not come up with only by themselves.
I knew the rough outlines of the whole dblspace and DOS 6.22 but it was great to get all the details and corporate wrangling. It was the DOS 6 to 6.22 problems and a crashed disk that opened my eyes to what kind of company MS was. 1992-94 a tough time to grow up in the PC world.
Anyone else give a little cheer when Stacker won the 100M? Good stuff.
I remember laughing my ass off the day I read Stac had gone under for good...
They should have made a deal with Microsoft, maybe they would have lasted a bit longer before failing utterly.
I do recall being struck by the DBLSPACE disk corruption in the 90s. So many files lost and no internet to know how to recover them. This taught me the hard way to backup more frequently, and to stay away from any automatic disk compression solutions forever after.
For a moment with that intro I thought MS-DOS had SquareSpace included in the box XD
Ah the memories :-), I used stacker 4.0 on my pc of the time, it had 300MB and with stacker it was (almost) double, only thing was, it could take all night for it to defrag the harddrive, I would lie in my bed listening to the sounds of the harddrive working until I eventually fell asleep 😁
I compressed my brother's 486, it slowed to a crawl😟
We had Stacker on our 386 PC that only had a 60MB hard drive. It worked great. The only issue was the fact that it was a TSR program that took up precious memory.
Better question:
Was there ANY Micro$oft product that wasn't stolen?
Didn't Bill write MS BASIC? I know he did not create the language I mean the tool, And they did buy QDoS
Thanks for this. I recall using MS-DOS 5.0 and Stacker successfully together for several years in the early 1990's with my trusty Leading Edge 286 that had shipped with a 30mb HDD.
First! Greetings! ;)
Congrats! Saw two when i clicked it. Might be within the top 10 myself.
I miss the days going to the store to buy actual software. I still use floppy disks to store config files, wallets etc.
I used to use DoubleSpace myself back in the old days on my HP 386 DX20. Seem to remember i had a 20mb HDD. But the performance hit of using doublespace was huge on a little cpu...
Nice history lesson, thanks for bringing up those memories.
But with the advent of Windows 95 and the ever increasing hard drive sizes, Microsoft should have phased out the disk compression. But no, even in Win10 you can tick the box "Compress this drive to save disk space" which does absolutely nothing, except slow down the system, because most of the files today can't even be compressed anymore.
I had dozens of clients over the past decades who thought it would be smart to use this option only to find out that their systems became unusable. Great stuff, Microsoft.
I seem to remember some PCs in the UK being advertised with Mahoosive hard drives, while the fact that compression had to be used was in MUCH smaller print!.
This was a fantastic video, I was always confused about the Doublespace vs Drivespace utilities. Also wondering what was the deal with MS DOS 6.22 being more popular.
Thank you! for mentioning DR DOS 6.0. I believe it shipped around the same time as MS DOS 5.0 and was streets ahead. I convinced my father to buy it to run on his IBM PS/2 and we found it a great OS with many advantages over MS DOS 5.0.
Of course, MS was its usual bully self, seeing others' good ideas, copying them, and then crushing them.
What I found most commonly turned out to be the case was whenever upgrading to a bigger hard drive, that it was far easier and simpler for me to buy a much bigger drive capacity and soon I ended up with disk drives in the high gigabyte range. If you buy a 700GB drive you get most of that as usable space after formatting is complete. Some older versions of Windows actually were a little shaky on disk sizes over a certain limit and would either create multiple partitions or be unable to reach the latter portion of space out of addressing reach. Newer versions did of course fix this but one could never have enough disk space it would seem! :D
Every hardware and software combination has disk/partition/file size limitations. We ran into this numerous times over the years, and it still happens today.
Bill "Stole" a lot of software. He initially either bought you out, or licensed the software and then bought you out, or had it long enough to make a derivative. He was definitely a business man, more than a computer genius or guru.
MSDos was stolen in the first place. IBM wanted to use CP/M but couldn't get in touch with Gary Kildall, it's creator, so they showed it to Microsoft and said "We want something like this". All Microsoft did was to steal CP/M, rename a few commands, then ship it as MSDos.
Gary Kildall did eventually get a payout from Microsoft (a mere $50,000) by way of "recognition" but it was way too little and way too late.
@@Kevin-mx1vi Bullshit.
Did you just make that nonsense up, or did you read those lies somewhere online?
IBM didn't "want" CP/M, it was Gates who sent them TO Kildall and Digital Research, to check out CP/M, at the SUGGESTION of Bill Gates. This is historical fact. Microsoft and Gates were already working FOR IBM - writing a BASIC interpreter for the upcoming IBM PC. But Kildall, being Kildall, screwed up making the deal, (and there are multiple stories of how), and lost the chance to become Bill Gates. So IBM went back to Microsoft, and Gates, being Gates, (smart), sensed opportunity and didn't screw up. Microsoft BOUGHT the rights to 86-DOS, (QDOS), from SCP, (for a "mere" $50,000), modified the code to meet the IBM specs, (which made the new "MS-DOS" far better than anything CP/M had to offer at the time), and the rest is history.
Microsoft never paid Kildall a dime - there was no reason to, they didn't owe him anything, and he didn't deserve anything.
Those were the days I remember using dos 5.0 with stacker 2.0 for a long while until eventually moving to dos 6.22. The whole reason for using drive space doubling technology was Falcon 3.0 at the time I had a 210mb drive
Interesting, it quite explains the accident I had in 1995 with DoubleSpace. I can't recall if I had MS-DOS 6.2 or prior - but seeing this I presume it was pre 6.2 - certainly something went very bad one day. It began with a crash, and I had to reboot. Then NDD found thousands of "lost chains" and I lost a large amount of data. It all ended with a format and I never returned to DoubleSpace nor did I ever try DriveSpace (Win '95 was far too heavy for my old computer).
Loved it! Great video and I remember all this when it happened. There was a shareware program called Diet that "kinda" did the same thing before too, it would work on the file level and intercept read and write commands using a TSR
nice to know the pass... cuz many of us come after these events and would be nice to know the history of somethings....... keep it up ... goood job bro....
Those were the days! My fresh-faced and eager young self had talked a few good-sized law firms and another couple CPA firms into allowing me to be in charge of their IT needs. I was excited as it looked as though my future was set. Indeed, it was set alright. DoubleSpace was but the first of many curses that would plague me over the next twenty years and have me sleeping under desks on office floors rather than my bed most nights. I look back on it now with a bit of nostalgia, a badge of honor even, but I lived in a state of constant hyper vigilance and dread in the knowledge I was only one bad backup or crummy software update away from the combined and focused hostility of a hundred attorneys and their savage secretaries!
This was fascinating, and well made, thanks Nostalgia Nerd! How comforting to know that Microsoft has been dirty since the good ole days of DOS, ahaha
I tried using the DOS double space and drive space, never had a lot of luck with them. They seemed to slow everything down way to much for my taste, I was one of those idiots who was always searching for faster operation of my computer! I have recently given up on such a search when my wife, last year before Christmas told me she was giving me 500 bucks to buy a new laptop. She said I knew more about what I wanted, and she felt guilty for causing me to spill coffee on my Macbook Pro when she grabbed my arm as I slept in my recliner, a full cup of coffee in my hand and my Macbook on my lap. So I shopped around for days seeking the fastest machine I could find for 500 bucks. At long last I settled on a new HP laptop, the specs were fantastic although the screen was a bit small compared to the desktop replacement machine I had been running. Man when that machine got here, it was Amazing! I am still using it as I type and it still is fast as hell. It boots in seconds to either Win 10 or Linux Mint that I use as my main OS most of the time. She does everything I ask and never blinks. That said I don't think I would use double space on it if I wanted more space, I would probably buy a new hard drive, or, perhaps get rid of a bunch of movies I don't need to store on it.
