Foremost is a forensic program to recover lost files based on
their headers, footers, and internal data structures.
.
Foremost can work on image files, such as those generated by dd,
Safeback, Encase, etc, or directly on a drive. The headers and
footers can be specified by a configuration file or you can use
command line switches to specify built-in file types. These built-in
types look at the data structures of a given file format allowing
for a more reliable and faster recovery.
