recovers files by looking for magic bytes

 Magic Rescue scans a block device for file types it knows how to recover
 and calls an external program to extract them. It looks at "magic bytes"
 in file contents, so it can be used both as an undelete utility and for
 recovering a corrupted drive or partition. As long as the file data is
 there, it will find it.
 .
 Magic Rescue uses files called 'recipes'. These files have strings and
 commands to identify and extract data from devices or forensics images.
 So, you can write your own recipes. Currently, there are these recipes:
 .
    * avi
    * canon-cr2
    * elf
    * flac
    * gimp-xcf
    * gpl
    * gzip
    * jpeg-exif
    * jpeg-jfif
    * mbox
    * mbox-mozilla-inbox
    * mbox-mozilla-sent
    * mp3-id3v1
    * mp3-id3v2
    * msoffice
    * nikon-raw
    * perl
    * png
    * ppm
    * sqlite
    * zip
 .
 This program is useful in forensics investigations.
