Anti-Twin is meant for performing file comparisons by searching your hard drive for duplicate or similar files.
The process is relatively fast. Any similar or identical files found can either be sent to the recycle bin or directly deleted. By doing this process periodically, you can free up hard drive space.
To use Anti-Twin, you can select the option Compare file content; this compares the entire binary content of the files, meaning that the file names are irrelevant. You can also opt to compare names and set the match percentage.
Anti-Twin can be used to find and delete duplicate MP3 files in a download folder or find similar images, cleaning up file repositories, i.e., by searching for unnecessary file copies and redundant data back-ups.
