Photorec

PhotoRec is 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.

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. PhotoRec searches for known file headers. If there is no data fragmentation, which is often the case, it can recover the whole file. Photorec recognises numerous file formats including ZIP, Office, PDF, HTML, JPEG and various graphics file formats. The whole list of file formats recovered by PhotoRec contains more than 390 file extensions (about 225 file families).
