Forgot to say I'm using minGw with Msys latest version:
mingw-get-inst-20120426

Sorry about that

Subject: mv fails when trying to overwrite a file in a (map) network drive
To: bug-coreutils@gnu.org


If I am working in my harddisk I can move and overwrite files.

I'm working on Windows XP I have a network drive (Y:\)
file1 exists
file2 exists

if I try:
mv -f file1 file2

It complains:

mv: cannot move `file1' to `file2': File exists

Hope the explanation is good enough.

Cheers,
Lluis
