If you want lfn for dos, have a look at http://taniwha.org/lfn.zip
I'm not sure what state it's in and you probably need my latest djasm hacks
(same site: http://taniwha.org/ ), but I had it working for hd and fd access
under several versions of dos. While I haven't looked at the code for a couple
of years, I'm very willing to help sort things out with it.

A few gotcha's:
 o  case sensitive
 o  MAKEFILE.IN and Makefile.in.in are different files (even without the case
    sensitivity; I almost went on a homicidal rampage when this gave me grief
    under windows)
 o  new short names for long names are a pseudo base64 encoded 48 bit crc of
    the long name (encoded in the range b0-f0 (skipping e5) iirc (the only 64
    range of chars dos didn't mangle))

However, fat32 is supported though not recently tested and then only reading
tested.
