PhotoRec is a file data recovery software designed to recover lost files
including video, documents and archives from hard disks and CD Rom and lost
pictures (Photo Recovery) from digital camera memory. PhotoRec ignores the
filesystem and goes after the underlying data, so it works even if your media's
filesystem is severely damaged or reformatted.
