What is the Smallest Possible .EXE?

- What is the smallest possible EXE that can be run on the Windows Operating System? What about the largest possible EXE? What even is an EXE file? On Windows, EXE files use the Portable Executable file format, which contains the program's code, data, and references to other libraries that can be loaded and run by the OS. It is often referred to as an "Image", the captured state of the program in a form ready to be run by the system.
After testing it was found that the smallest EXE on 64-bit Windows is 268 bytes. This is a system limitation and not a limit with the Portable Executable file format itself. The smallest EXE runnable by other versions of Windows are as follows:
Windows XP: 97 bytes
Windows 2000: 133 bytes
Windows Vista/7 (32-bit): 252 bytes
Windows 7/10/11 (64-bit): 268 bytes
The largest EXE possible is 1,996,488,704 bytes. Again, this size is a limitation with Windows.

Just to be pedantic, the first file isn't actually 0 bytes. But its contents are!
But the file is nothing but its contents. Unless you're considering the directory entry of the file system part of the file, in which case you would also need to consider the filename and all the files metadata part of it. To my knowledge it isn't though. Directory structure is kept completely separate from file contents
@@HeyImSolaceFiles on your computer are stored with overhead. Some tools will tell you your file has a size of x bytes, and a size on disk of y bytes.
This difference will exist even if the contents are 0bytes, since usually the system reserves a section of disk for it.
This difference is op's 'being pedantic'
O Archon się tu zjawił.
@@mars5train601 I know that this overhead exists, but this overhead is not part of the file. This is like saying a Google search result is part of a Website. It takes up space, but it's not part of the website itself, it merely shows some data of it (Title and a little preview) and points to where it is (its web address).
@HeyImSolace nah, thats the difference in memory vs storage.
The file's metadata in the inode table has a minimum size. In windows ntfs (from googling), the equivalent looks to be the mft record, which clocks in at 1kb or 2 512B ssd sectors.

I thought the same thing lmao
I don’t understand your technical, so you mean like make a file that run beep/ small sound?
@@ping_th the NE555 is a small IC (integrated Circuit) / Chip used in electronic devices for timing/clock signal (and more) purposes. This chip (and its clones) are probably the most used IC for such stuff. It is so easy to use and cheap and widely used it became synonymous for this kind of usecase. Since any note you can play is nothing more than a sine wave with a specific frequency and the NE555 can easily produce such frequency you can use this chip to build a small piano (ignoring it not producing sine waves but square waves you then have to filter)
If he manages to shrink that by another 45 bytes, it'll fit into a boot sector and will clearly kick pac-man and doom from the most popular choices.

Fun video.
ANSI (usually spoken as "ahn-see") control sequence originated with the Digital Equipment Corporation VT100. The SGR (Set Graphic Rendition) sequence was extended in "ANSI.SYS" on DOS to allow setting foreground and background colors. The glyphs the video shows beyond the ASCII characters are the VT100 graphics set, so the same program game would work using a serial port connected to a VT100+ terminal emulator that supported the color extension.
The flickering could be reduced by only redrawing the bottom row except as the meteors shift down. Using save cursor and restore cursor sequences could improve keeping the little house's position from flickering. This will take more code code, of course.
Yeah and similar usage of ANSI is also great for anyone who enjoys torturing themselves making unnecessarily complicated batch files. Using it to clear lines and restore cursor positions instead of simply clearing it is much more pleasant and opens up some cool possibilities that wouldn't be possible (or practical) otherwise.
*usually pronounced an-see

With the parameters now all in place, we can build Jorge Luis Borges' library of Babel, but for exe files. Since there's a limit to the number of bytes that can go in an exe and a finite number of values each byte can have, we can imagine a filesystem the contains every possible exe file. But it couldn't be a Windows filesystem.

One thing about compressors like crinkler is that you'll always have the potential hazard of the output executable being detected as possible malware. Most AV is leery of anything that looks like it's compressed, since it's a common way to hide telling features of the executable.

10:56 those aren't actually ASCII characters (except for the @)
ASCII is only a 7-bit encoding, and thus only contains 127 characters. anything beyond that into the 8-bit realm is a vendor-specific extension beyond ASCII
Where's the 128th value?
@@sttate the 128th value is the number 127. the 1st value is the number 0
@@shallex5744 not only the value (not number) 0, but also the NULL byte. Sometimes used as a string terminator so not exactly a character, but if you think of the other control characters as a character, it can be argued that NULL is also one, which makes a total of 128 characters. Also, back in the day the remaining 128 values used to be known as high-ASCII which were more or less vendor or machine specific. Later they became code pages which were more or less standardised.
If you actually look at the image that you complain about, you first notice there are 16 rows with 8 columns, which excluding the NULL character makes for 127 characters. Then you notice that columns have 3 bits and rows 4 bits. Which is exactly 7 bits. And then you notice that those are precisely the ASCII characters.
@@marsovac i wasn't focused on the image, i was referring to him suggesting that the house and the horseshoe-looking thing were ASCII characters
Back in the day, we called it "Anne See" (like "antsy" with a silent "t"). not "Ay En Ess Eye"

Back in the days of DOS, we (Crescent Software) sold a library for BASIC (called PDQ) which would allow for the quick compilation & linking of EXEs less then 512 Bytes. Why 'so big' (LOL)? Because that was the size of *ONE* sector on a *FLOPPY DISK*. Anything less was moot.
It could also create TSR (Terminate & Stay Resident) programs, which were available with a keystroke or interrupt. And we could shove them up into Extended, or of you remember it, "Expanded" memory.
Since this was in the days prior to math coprocessors, I wrote the 8087 emulator for the product.
Thanks for the nostalgic trip down memory lane.
did it compile basic into a more native program instead of the more usual of adding the basic intepreter and the bas itself into an exe?
I remember trying to coax borland c/c++ 3.1 into compiling as small executable as possible (I think I was like 11 back then). i think i got a 'flame' effect down to 8kb or so, which was still huge for what it was(just couple of loops really and calling bios to change the video mode and make the pallette).
@@lasskinn474 LOL! Yeah, these were genuine EXE files. The BASIC compilers BC 6 & BC 7 Professional were actually pretty good compilers for the time. BASIC code was lexed into 8086, 80286, or 80386 instructions. It even had math coprocessor options. statements like Print, Play, Open, Locate, REDIM, Strings, etc., generated calls into the runtime libraries just like C functions.
We re-wrote the runtimes from *SCRATCH* in hand tuned assembly language (MASM). Because our libraries were so granular, the linker was able to bring in just the bare bones set of library routines that the programmer actually invoked. Nothing was just along for the ride.
Since it was a library we were able to add extra functionality, such as the TSR capabilities, interrupt handlers, function pointers, pretty much anything a C coder could do, we put that power in the hands of the BASIC programmer.
Then came Visual Basic for Windows. But that's a story for another day.

Writing small programs under an OS is fun. Try writing a bootable game :) People managed to pack whole simulations or games into the bootsector of a floppy. A sector has 512 bytes but the last 2 bytes are required or the BIOS won't recognise it as bootable (55AA in hex). Though the bootsector (depending on the medium) also contains some volume information. That only leaves a little bit left for the program. People have written bootsector games or simulations and still have the disk to work properly under DOS or windows. Also there are no sys calls to any OS function since we ARE the OS if we boot from this medium. All we have are the BIOS interrupts and direct memory access. The BIOS only loads the first sector (boot sector) of the medium which usually just contains code to load the actual OS boot loader from other sectors.
back in the day booter games on dos machines were not that common but there were a bunch of them. if you had only 1 floppy drive you didn't need to swap from dos, you didn't need to worry if the customers config.sys was weird etc and could have more confidence in whatever tricks you used to make it harder to copy the floppy.
i think that there were those titles is one reason for why booting from floppy was default for so long on pc's so you couldn't leave a floppy in the drive.

Just as a comment here, you don't want to do things like cmp al, 0. The reason is simple. You're comparing an immediate value and that value has to be stored in the instruction. Since you're only interested in the flags, you should test al, al whereby the assembly doesn't need to store the immediate value and it will set the flags for you to branch against.
Thanks, I had forgot about TEST, looks like I can shave off a few more bytes
@@InkboxSoftware Well when you've done as much assembly as I have and enter 4k/64k demo competitions at Revision and other parties, every byte does indeed matter!
Good video though.
In practical terms, the smallest .exe file you can have is the cluster size the FAT uses on the storage device you're using. Assuming you saved your work that is.

linking an extra dll just for a rng is costing a lot of space. Ok not really a lot but you can do better. It would be smaller to implement a LFSR rng using a seed value from whatever source you can get that you're already have access to. A Console handle is probably good enough to use as a seed for a LFSR. The Handle values are likely going to be unique every time you run the exe though not guaranteed, the chances you'd get repeated Handle values are extremely unlikely. Or you can just go straight to using a cpu random instruction but you lose compatibility with old cpus.
17:41 This is close to 1.99 Gigabytes for those who don't know.
would you save some space if you used RDRAND or RDSEED instead for the RNG?

That comment about every Windows executable having the same DOS header isn't true. You could specify an actual MS-DOS application as the header and create a dual-mode application. The same .EXE when run under DOS would run only the DOS "header" portion, while when run from Windows would skip over the DOS header and execute the Windows code.
Many applications used to do this back in the day - and I've even created a few myself!
That's true, and that's why it has an MS-DOS header in the first place. It's just nowadays your standard compiler will fill in the string "This program cannot be run in DOS mode" automatically.
Older compiler uses slightly different string "This program requires Microsoft Windows".

In DOS, the smallest EXE that will do something is 2 bytes. If an EXE contains "@e" it will reboot the computer when run.
That sounds more like a COM file. EXE files *must* start with "MZ" to be valid; and then also contain a header (very similar to the one used by EXE files for Windows).
COM files, on the other hand, were literally just something DOS loaded into a page of memory and then jumped to the first byte of. The smallest valid COM file is 1 byte, the encoding of the "RET" instruction (hex code C3). That would just immediately terminate and return control to DOS.
Last time I used DOS/Windows (c. late 1994), you could rename a .COM file to .EXE (and vice versa) with no effect on how it would run.
@@pdr. Back then they do checks for header within the file content instead of fully reliant on file extension.

I progressively deleted stuff until I was left with just @e and it would still do the same.

Looked into it a bit, correct me if i'm wrong but there is a way to make this smaller in theory: shellcode style import calls. Crinkler is importing every function from called DLL's, which is cool but doing it on your own using shellcode style function calls would be smaller I believe? Would make rhe actual assembly code longer but would make the post linking DLL shorter
I'm sure you could apply a lot of shellcode techniques to make this smaller, but I'm sure both you and crinkler are also using a lot, have not had time to read the code in depth yet but that import area is my area of interest

Only a poor musician blames his instruments.
But can it run Doom?
That makes no sense

5:17 Okay, but WHY? WHYYYY in the world would Windows put a shrub there? What purpose does this serve?
what man, you ain't shrubbin? it's the new craze!
I think this is the first time I've ever heard anyone say "ay en ess eye" instead of "an-see"
ELF gets smaller.
What is an elf?
Not sure if you already know about this, but you might be interested in Cosmopolitan libc, a project to compile c code to a polyglot binary running natively on Linux + Mac + Windows + FreeBSD + OpenBSD + NetBSD and even in BIOS
0:29 is that a CCP song lol
Yes. It's called "without the communist party, there will be no new china" or something like that
i really like the explanation on what an .exe file is and exactly how they work, very interesting and easy to understand
You could fit the entirety of Minecraft into a exe lol
yes? most games can be fit in an exe. in fact that's how games work. they are exes.
@@thewhitefalcon8539 you dont get my point...
@@thewhitefalcon8539 He refers to all the DLLs, libraries, files, external to the Minecraft JAR or EXE file depending on the game edition (Java or Bedrock)
@@thewhitefalcon8539he means the entire game, not just the "executable" portion. (using quotation marks since it's java which is a VM and not a real executable)
Yes, but saves
'William Gates' actually threw me for a second.
