DuMP3 is a general purpose 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.

text data for each file and then comparing the fingerprints. Will mark all files that can not be read or decoded correctly as corrupt.
