Is there an easy way to get to the basename (file name without extension) of a DOS file name using the DOS BAT command language?
I agree: format c:\
is probably a good start, followed by a bootable Linux CD (assuming these antique machines have a CD reader - not a given). But let's pretend that we only have DOS... (That means: not Windows - not even Windows 3.1, let alone Windows 95, 98, NT, ME, XP, Vista, 7, etc.)
