Thanks to Eric's port of the dosfsck, so we have a tool known to support
LFN (if I understand correctly).

I think, as long file name entries are stored as directory entries with
"label", "hidden", "system" attribute, they are not likely to be damaged by
a chkdsk program if the disk logical structure is in good condition. On the
other hand, for some defrag program that reorganizes file name sorting in
the directory, if that program doesn't support LFN, it is likely to damage
the order of the LFN, -- but I'm not sure if the order is important in the
LFN entries -- maybe yes?

Best regards,

Robbie (Decheng) Fan
