Forensic Toolkit, or FTK, is a computer forensics software made by AccessData. It scans a hard drive looking for various information. It can for example locate deleted emails and scan a disk for text strings to use them as a password dictionary to crack encryption.The toolkit also includes a standalone disk imaging program called FTK Imager. The FTK Imager is a simple but concise tool. It saves an image of a hard disk in one file or in segments that may be later on reconstructed.
