Ashampoo Duplicate Finder finds and deletes redundant files and lets users reclaim their disk space. To ensure that your applications continue to work without issues, the program keeps a master file and replaces all redundant copies with hard links to that file. When an application tries to access a deleted copy, it will then use the master file instead. It's a smart approach that completely avoids file issues and just isn't feasible with manual file deletion alone! But where do duplicate files come from? They can be caused by repeated downloads or program setups that each supply their own copy of system library files. Even Windows itself tends to create redundant files across drives and save locations. Ashampoo Duplicate File Finder scans Windows systems at blazing speeds and presents the results neatly arranged by file type, including documents, audio, and video files. Users can review individual matches and permanently exclude files from deletion, if needed. Extensive tests have shown that duplicate files can occupy a significant amount of disk space while providing little to no benefit other than file redundancy. Replacing them with hard links to a single master file instantly frees up disk space at no noticeable performance cost and little, if any, risk. And Ashampoo Duplicate File Finder comes with a failsafe: A backup is created prior to every system modification so users can revert it in a matter of seconds!
