Is the purpose of this script so that if MM crashes and has to be reinstalled you don't have to rescan all your music?
When I go to backup:
Am I supposed to specify an output path? (it's just says C:\)
Should I check "output archive"?
Yes, it saves all the essentials to another directory or disk in case your original stuff gets lost or corrupted - or you make a mess of it
In output path enter anything you want as long as it's a valid directory, e.g. X:\My Documents\MediaMonkey
Don't bother with the output archive stuff unless you're really pushed for disk space - it just zips the archive. I've never been able to get it to work anyway.
Hope this helps.
