createfile is useful for filesystem limits testing, or just for creating
a binary file with a specific size.
you can download the source code and executeable as a single createfile.zip file.
it is now available as a DOS version as well as a windows version.
It is under the GPL3 license. lsm file.

unpredictably. check your disk space first and make sure you
get your numbers correct and leave yourself enough disk space

usage: createfl [-?] [-h[elp]] [-v[ersion]]

filepath]
createfile fills file at filepath with integer data bytes, 63-bit-integer bytes
in size.
integer can be decimal (plain or starting with 0d), hex starting with 0x, octal
starting with a 0 0o or 0q, or binary starting with 0b.
-filepath default is .\JUNKFILE
-byte default is 0x00. you specify an 8-bit integer.
-random is used or -byte. -random fills with random data (slower).
-size default is 0
-h or -help or -? or no arguments gives this help and exits.
-v or -version gives the version number and exits.
Performance: 1GB/min on a SATA II drive. 512MB/min on a busy computer.

gcc compiler note: -fpack-struct cannot be used with iostream or anything to do with libstdc++ (including locale which includes iostream) without getting lots of errors.
The dos version is compiled with DJ Delorie's djgpp (gcc for DOS). It can be obtained at DJDelorie.com/djgpp.
The windows version was compiled with Borland C++ 5.5 (free edition). It is available at article (may include patches), free compiler (requires regisration).
The windows version was also compiled with MinGW 5.1.4 which is a GNU compiler set for windows. it has the peculiarity that it requires any use of __int64 to #include <basestd.h>, and it also doesn't allow 64-bit constants in the microsoft/borland style of appending i64 to the number. it requires you to use the gcc LL instead, however, printf does use %I64d rather than the normal gcc %lld. If you use %lld, your program will crash and do the DrWatson error report thing.
