I think I found a bug in FC.EXE (File Compare “DOS” command) under win2k.
the syntax of the command is:
fc firstfile.txt secondfile.txt
If “firstfile.txt” has the offline attribute turned on, fc.exe tells the
user that it couldn’t find the file, even though my driver found it and
returned status_success on a findfirst in my QueryDirectory code.
If I reverse the order of the file names on the command line, it works -
even though the offline attribute is on for “firstfile.txt”. If I turn off
the bit in QueryDirectory (under the debugger) when “firstfile.txt” is first
in the argument list to FC, it works.
I wanted to document this here, incase someone else finds this bug; but
should I report it to Microsoft to help them have a better product? 
If so, is there an easy way to report the bug, instead of calling support?
Regards,
Greg
Hello Greg,
Do you reproduce the same behavior without your filter driver installed?

Oleksiy,
Well, I don’t know, because I can’t get a file onto the C: drive (ntfs
volume) with the offline bit set (by definition, the file can’t be offline,
if it’s on the c: drive, I guess). I also don’t have any other offline
media to try this on, unless someone could help me figure out how to do it
on a zip drive or floppy disk.
Regards,
Greg

Hi,
I can confirm your observation. FC.EXE (on W2K) fails if the first file has
FILE_ATTRIBUTE_OFFLINE set. It works w/o this flag on the same (my) file
system.
Funnily enough: I read this original post and now few days later I tried to
figure out why fc tells me that it cannot find a file which is obviously
present. Took several minutes until this post came back to my mind 
Regards,
Detlef Golze

Thanks Detlef - I appreciate you confirmation of this problem! Does anyone
in the group have a logical explanation for this, or is it a bug?
Thanks again, and regards,
