Discover Duplicates: Anti-Twin

Anti-Twin is a small software application which compares files, i.e. it searches for duplicate or similar files on your hard disk drive. All similar or identical files that were found can either be sent to the recycle bin or directly deleted. This will increase the hard disk space on your computer.

Select the option “Compare file content” to compare the entire binary content of the files. This means that the file names are irrelevant. Here, the basic principle is: “Name is but sound and smoke – size matters! And never lose sight of the inner values.”
