Anti Twin - Remove duplicate files from your computer and free disk space

Emptying your Recycle Bin and clearing away temporary files are a good first step in cleaning up your system, but there’s another type of hard drive clutter which is a little less obvious: duplicate files. You should scan for duplicate files and remove them as soon as possible if you haven't created then intentionally. These can consume a surprising amount of hard drive space, but fortunately tools like Anti-Twin make it easy to detect and delete them.
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

The program includes subfolders automatically in the scan, which you can disable if you prefer it to only scan files in root folders. A click on file filter displays additional filtering options, in particular to only include files that match a minimum or maximum file size, or files with specific extensions.
This tool can help you to remove all files that are twice or more than once in computer

The program does have a few issues, in particular with performance: scanning and comparison speeds aren’t the best. It’s still perfectly usable, though, and the sheer weight of its configuration options mean Anti-Twin deserves a very high ranking on your duplicate file finder shortlist.
Comparison can be done in two ways, by content and by names. Comparison by name is important but cannot do the job all by itself. Matching percentage determines how similar the files can be. For 100% match, file-names have to be totally similar-including file extensions.Can be used to remove same files of all types. Selecting the different extensions option allows the program to ignore file extensions. The identical file size option compares files according to their sizes. This will thus help to remove duplicate songs, pictures or downloaded images which may contain the same data but are stored with different names. Comparison by content involves a byte by byte search which yields better results than comparison by name. The two methods of comparison used together achieve the best results. This is one of the most advanced similar file searcher.

How to use duplicate file finder
The user interface is well arranged but the horizontal sections are too monotonous. To begin searching, select a folder to search and hit the search button at the bottom of the interface. The various search options can be quite confusing and the fact that no manual is available doesn’t make things any easier.
