If it was in fact removed from the "official" MS-DOS, and one wanted

open-source recreation of OS/2 would help? It has a FAT32 driver which
is compatible with the OS/2 IFS and, as I recall, OS/2 was more of a
direct successor to MS-DOS than Windows ever was, so perhaps its code
would be more helpful to a DOS dev as opposed to the Windows versions.
Not sure, I haven't dug too deeply into that myself, but hope it
possibly helps.

FAT32 is pretty much just an extension of the FAT system which is after
all the underlaying filesystem since DOS 1.0 (and 86-DOS, as that is
what Paterson gleaned from Marc MacDonald at Microsoft), it is not an
additional "installable filesystem". Don't know right now how long
filenames are being handled, but as they only came out with Windows 95B
(and I don't recall right now how this was exactly handled on Novell :(
), it was well after DOS...
