FAT files definitively can't be bigger then 4GB (ignoring FAT+) because the
'file size field' has only 32 bits.
I am *mostly* sure that
file size was limited to 2GB in MSDOS < 6.2
file could grow to 4GB if you indicated 'I am aware of signed/unsigned
problems'
at file creation/opening time
I am *mostly* sure that
FreeDOS just has a 4GB limit.
it's not that complicate to test this - and ascertain or deny this.
as a side note: disks bigger then 1GB just weren't available at MSDOS times.
so this was never a theme.
