DuMP3 is a duplicate and similar file finder. It finds exact duplicate binaries by hash, similar text files by substring content, images (JPG, BMP, GIF, PNG, etc) by color and audio files (MP3, WAV, OGG, etc) by wave data. Future: fonts, video.
Pretty hopeless. Not even basic instructions on how to use this.
Comes with a bunch of 32-bit JARs that will kill your 64-bit JVM. Wait until this is redone in a modern language.
Looks like it has potential, but isn't very usable. No installer or anything. "Java Virtual Machine Launcher Could not find the main class: net.za.grasser.duplicate.DuMP3. Program will exit."
