The following are some of the best results using CleanUp! to delete files that users have reported. Notice that the top recoveries exceed quarter of a million files - that's a lot of junk that Windows and Windows programs leave behind. That's why you need something like CleanUp! If you managed to recover more than 50,000 files using CleanUp! then let me know (see Take the CleanUp! Challenge for details).
