From the developer:
TidyTop makes it fast and easy to clear your desktop and restore it later. Archive your files using TidyTop. TidyTop helps you to identify files on your desktop you haven't used recently. TidyTop moves all or selected items from your desktop into an archive folder which is still accessible from the Finder or other applications. No data is deleted.
