PC Tools File Recover: Recovers files from hard drives and other media
Screenshots
When you delete files from your PC, you don't really wipe them away forever. The system simply marks that space as reusable, which means that erased files can actually be recovered with apps like PC Tools File Recover.
This program features three different modes (Quick, Deep, and Physical) to scan your computer in search of previously erased files. I especially liked the possibility to filter this scan, either by file type, file size, or even specifying letters or words that must be found in the file's name.
However, I was disappointed to see that this trial version doesn't allow you to recover any files. It scans your PC and displays the list of all erased files, but if you want to recover any of them, you'll need to register the program. I understand this is a shareware version, but I think users would like to have some kind of guarantee that they'll be able to recover their data. And maybe a good way to do so would be to have a fully functional version for a limited period of time or at least allow users to recover a few files before registering the program.
