EF Duplicate MP3 Finder is a useful tool that lets you locate duplicate audio files on your PC.
If your music library is a total mess left over from the days of pre-iTunes online downloads, it's probably difficult to tell just what exactly is in your collection, let alone whether you have more than one of the same song file.
Your files might not be properly labeled or even start with the CD track number. These are all things that make sorting through your library to find duplicate files a bit of a pain.
EF Duplicate MP3 Finder searches for duplicate audio files, looking for those with the same or similar properties. It does this by analyzing the ID tags the audio files contains, specifically pertaining to the artist and title information. EF Duplicate MP3 Finder then compares that information to other audio file tags.
EF Duplicate MP3 Finder uses audio file names in the event that tag information is not available. EF Duplicate MP3 Finder allows you to adjust your search options to search for files with similar names instead of identical properties as well, which is useful if you think you have files where the artist or song title are spelled incorrectly. MP3 Ogg/Vorbis, WMA, and FLAC audio formats are all supported. Unfortunately, EF Duplicate MP3 Finder is missing support for several others like MPEG-4 and AAC.
EF Duplicate MP3 Finder is a competent little tool to help you quickly and effectively organize your audio file library.
