FSUITE Forensic Utilities
Supported OS: can only be run in DOS, but can be used on any FAT filesystem.
Computer Forensics software for FAT filesystem. Works on virtual machines. Can be boot from floppy, USB, or CD. The suite consists of 5 utilities used to recover lost or deleted data in the FAT filesystem. The reverse is also true, using these utilities you can make it impossible to recover data from a storage device. It all depends on how you use it.
The files are executables, require no registration, no product keys, nothing. They never expire. Each utility comes with a corresponding text file that explains what the utility is meant to do and the basics on using it. There is no installation, you must be running in DOS mode to use the utilities however.
My personal advice: If you're using software of this type for the first time, run it on a virtual environment where it doesn't matter if you completely screw the system up. One mistake with this software can render a file useless.
