Recently I started getting the following errors from one of my batch files.
Invalid drive specification
0 File(s) copied
The problem was, that I didn’t have specified drive at all, because I was using UNC path (\\ComputerName\SharedFolder\Resource).
So, xcopy is reporting with the wrong error message.
One possibility is, that it is possible to disable UNC paths in xcopy altogether – see the Microsoft KB Q192808.
In my situation, error was caused by broken network connection. Issuing:
net use \\ComputerName\SharedFolder\Resource /USER:user_name password
right before xcopy, fixed the problem.
Brilliant, worked like a charm. Thanks !
Also if you were smart like myself and using Windows 7. I opened the command prompt using “”Run as Administrator.” This is a different user than the one you are logged in as and so does not have the mapped drive despite the fact that it is listed if you type the command “net use”Ughh – just start the cmd prompt as yourself when using Win7.
