About CleanUp Pro
Gathers all your files in a folder containing many sub-folders, each of which contains a different kind of file. For example, every jpeg image is put into the “JPG” folder (demo) or “Jpeg Images” folder (pro). The demo version only allows you to clean up the desktop, while with the pro version you can clean up desktop and folders, and undo both operations. Also, the pro version gives complete names to the folders it creates (for example, “Microsoft Word Documents”), while the demo only names folders after file extensions (for example, “DOC”). Last, but not least, the demo version only recognizes 20 extensions, while the pro version relies on a database of more than 100 extensions.
