That's because GNU tar will translate the path F:/ to the
/ directory on *host* F, not quite the same thing you thought
it meant. This feature is quite well documented in GNU tar's
info file, and even says so when you type ``tar --help'' (see
the last paragraph that explains the meaning of ARCHIVE)!

Joey's problem lies elsewhere, and quite possibly in the program
he's talking about. Cygwin does do the translation where it's
possible/unambiguous; for example, ``ls c:/'' does produce
the expected behaviour, and ls doesn't include any special 
magic to handle this AFAIK. Just try it with gcc, and that'll
work too.

Mumit
