PhotoRec is free - this open source multi-platform application is distributed under GNU General Public License (GPLV v2+). PhotoRec ignores the file system and goes after the underlying data, so it will still work even if your media's file system has been severely damaged or reformatted. PhotoRecis file data recovery software designed to recover lost files including video, documents and archives from hard disks, CD-ROMs, and lost pictures (thus the Photo Recovery name) from digital camera memory.
You can the browse the contents of this file to safely restore the files you wanted back to their original location. When the program is done restoring the files, the restored file will be located in the recup_dir folder. If you wish to specify the types of files it will restore, you can use the File Options screen to make these changes. By default, PhotoRec will recover almost all deleted data files that it can find.
PhotoRec will scan a hard drive for deleted files and automatically recover them to a location you specify. PhotoRec is a free file recovery tool that is bundled with the TestDisk program.
