yes it is.  and the forward slash or backslash is handled perfectly by
all windows internals - it's only windows command prompt that had an
issue cause it uses '/' as an option identifier.  The system itself
allows // or \\ or / or \ anywhere / or \ appear.

Not specifying the drive is also valid - it means use the current drive.
