It recovers files from the trash after it's been emptied, and files from formatted, corrupted, or unmountable disks. You'll be surprised at what it'll find. In the same way you browse through your regular files using the Finder, FileAngel will scan your disks for permanently deleted files and allow you to view them in a media rich file browser window. It works on virtually any kind of media, from standard Macintosh disks, to disks from other operating systems that are unreadable in OS X. It is also designed to withstand physical faults on the media it is used on, allowing it to skip over unreadable parts (whether it's a hard drive with the infamous click of death, a scratched CD, or a USB pen drive with bad blocks).
