You can have 112 files on the root directory of a floppy disk.  Putting files
in folders makes the number limited to free space.  I'm not sure of the hard
drive limit; older Supra software has a limit of 256, although I personally
have seen 500 files on the root of a hard drive.  The limiting factor is
not the FAT; it's the directory space on the disk.

I believe fopen() (or whatever GFA's equivalent is) will return some sort of
error code (negative value, possibly -49 or -36) in such a case.
