O&O UnErase analyzes your hard drive and finds these "deleted" files and gives you the chance to recover them – though you'll have to pay for the complete version if you want to actually recover those files. This limitation of the trial version makes this version of O&O UnErase a bit disappointing. Also, the advanced search tool doesn't include format filters (you have to manually enter the extension by yourself) and, more importantly, results are a pain to browse, all tucked in an endless list with too cryptic names.
