It’s possible that you’d want to restore all the databases you have backed up to  a specific folder. This will generate the scripts to restore those and move the files to a new destination. Copy the output from this query into a new query window and modify as needed before running.

Part of this code was taken from StackOverflow – I think this post in particular, but it’s hard to say for sure.
