Look at the FileCopy statement in VB Help. I don't know of a way to move a file but with FileCopy and Kill statements you can achieve what you need.
Try using Scheduled Tasks from Control Panel to open the DB at 5am and have a form that runs your code. I haven't actually done this but it loks like it would work better than using a form's timer event because there are optons for waking the pc up to run the scheduled tasks.
I'd further recommend not coding the Kill statement but rather, set up a table that logs the name and path of the files you've copied and delete them manually once you know that everything's working.
