Unstoppable Copier*: Recovers files from disks with physical damage. Allows you to copy files from disks with problems such as bad sectors, scratches or that just give errors when reading data. The program will attempt to recover every readable piece of a file and put the pieces together. Using this method most types of files can be made usable even if some parts of the file were not recoverable in the end.

Encopy: rescues data from damaged media when standard system copy fails, freezes and or rejects the media. In cases where it is not possible to perform a full recovery, Encopy will try to copy as much data as possible from the damaged files.
