Recuva (pronounced "recover") is a freeware Windows utility to restore files that have been accidentally deleted from your computer. This includes files emptied from the Recycle bin as well as images and other files that have been deleted by user error from digital camera memory cards or MP3 players. It will even bring back files that have been deleted by bugs, crashes and viruses!
Choose a drive to scan, wait a few seconds while Recuva looks for recoverable files
(those that haven't been overwritten on your hard drive), then review the
results. Select the files you want and click Recover. Presto: The lost files return.
