Dupin v1.3.4 Released
Dupin v1.3.4 provides compatibility with iTunes 7.7.1. All users are encouraged to update.
Dupin allows you to quickly find all sets of duplicate tracks in iTunes based on the criteria you choose. It can then automatically select the "Keeper" tracks from among a number of duplicates using your choice of a variety of versatile filter options. Tracks you decide not to keep can be purged from iTunes and their files optionally moved to the Trash. Dupin is flexible, fast, and easy to use.
