This program compares the MD5 digital signatures of two files (using the MD5 message digest algorithm) to ascertain whether those files are the same or different. (Any two files are byte-by-byte identical if and only if their digital signatures are the same.) It also compares file in two folders as to whether the files they contain are the same or different.

Here is a sample screenshot:

As an example of possible use, if you have copied files (and perhaps subfolders) in a folder to another folder (or to some external device) and later you wish to check which files have been added to, modified or deleted from, the folder which was copied, then this software can be used to find out by comparing the source folder with the target folder. The source folder or the target folder can be on any device, including CD-ROM and flash drive.
