Double File Scanner is a free software to find duplicate files based on SHA-1 hash. This feature makes it better than many other duplicate file finder tools. While most of the other software compare and find duplicate files by name, size, type, etc., this software compares hashes of files and then shows duplicate items. As we all know every file has its unique hash (that helps to check file integrity), so if two files have same hash, then they are essentially duplicates.

Once the duplicated files are detected, you can export the result as an XML file, and also delete any file. The software also comes with Automatic Clean-Up wizard. Using that wizard, all the duplicate items are removed in one-click. Files available in the source folder are kept by the software and files from the rest of the folders are deleted.
