dupeKill

Duplicate file finder/remover supporting the following hash algorithms: MDA, SHA1, SHA256, SHA256Cng, SHA384, SHA512 and BLAKE2B. This tool compares files based on content and lists any exact files which have exact binary duplicates. What sets this one apart is that you can give it hints about which files you'd like to keep before starting a scan. For example; if you tell it to prefer files with the 'most descriptive name', the app look at all duplicate filenames and default to the shortest, most descriptive name as the one to keep. A file with a name containing "copy of", or ".1.txt" would be considered less descriptive than one without; and a file named "lkePic.jpg" is considered less descriptive than "Lake Pictures.jpg". This way the default keep or remvoe action is pre-set; and time you spend going though the list and making changes to keep the 'right' file is minimized. The tool has many other options to choose from to pick the default 'kept' file: use the newest or oldest by date, the longest or shortest filename, or specify one or more directories where files should always be kept or removed.
