When extracting a tar file created on Unix, it tries to set
the user and group IDs on extracted files. However,
a) Unix uids and gids are maningless on Windows
b) It's not possible to set ownership of a file to
anything other than your own user ID on Windows.
Tar gives a series of errors of the form
"tar: Inline-0.25: Could not change access and
modification times: Permission denied"
I believe that tar should not attempt to set user and
If necessary, I can upload a file which exhibits this
behaviour. I haven't done so yet, because the smallest
such file I have is 27K in size when compressed, and if
the problem description is clear enough, a sample file
may not add much. If you want a sample, let me know
and I'll upload it.
