I would let those files stay where they are, the AppData is usually hidden so users shouldn't be able to manipulate/delete them. I would let them stay, as they're used to store your memory in the applications and software you're running.
They are folders created by Windows Live, each day when you open, for example Windows Live mail. They should be located in AppData/Local/Temp., and should be deleted automatically. However they are being created in the wrong place (bug).
