True, perhaps. I don't think Windows XP will fiddle much with SFTs though, except in NTVDM... ;) > Next point are the fnodes themselves: > f_count, f_mode, f_flags, f_diroff, f_dirstart, f_offset, f_cluster > and f_cluster_offset all seem to have exact equivalents in the SFT > slot structure.

Working directly with SFTs means bloating the code since these are "far" and not "near". The *far* fnodes can be eliminated and their purpose can be replaced by SFTs. Basically the fmemcpy() that is called in save_far_f_node() and xlt_fd() could be replaced by a function that copies things from or to the SFT for the fnode. Then all the basic functions (dos_mkdir etc) in fat*.c can remain unchanged. That way the two near fnodes become a purely internal FreeDOS kernel implementation detail within fatfs/fatdir.c; the permanent fnodes are gone. I mentioned this before; then Tom replied http://www.mail-archive.com/[EMAIL PROTECTED]/msg00493.html so we have the far fnodes in the HMA now and the rest is "planned to do for an unspecified date". In retrospect the near/far fnode change was a big step into this direction (seperating internal/external representation), it doesn't conflict with it!
