How can I extract the drive letter for a new mapped drive in a .bat?
I'm creating a simple command-line backup script to use robocopy to mirror "important" stuff to my NAS box. I would prefer not to rely on a hard-coded mapped drive letter for that NAS box. In the script I would like to map a temporary drive letter, copy the relevant files, and dispose of the mapped drive. I don't want to assume that if that drive letter is already mapped, that it's pointing to the place I expect. I also don't want to "assume" that some drive letter is available when I map the drive, thus the leading '*'.
