Dupin: Remove duplicated tracks from iTunes
Screenshots
Dupin is an organization tool that helps locate and remove duplicate files in iTunes. Want to get rid of all those annoying duplicate files you have in iTunes? Dupin's aim is to help you via an easy-to-use iTunes-style interface. It allows you to easily view your songs and playlists. You can search and filter songs based on numerous criteria like artist, album, or size, or by category, such as podcasts, audiobooks, and movies. Dupin locates files in Finder and in iTunes, and even finds duplicates in libraries from other users.
In terms of performance, Dupin can be a bit slow at times, and iTunes' own speed is slowed down when both programs are open at the same time. When searching for duplicates in smart playlists, Dupin is also not as effective as in normal libraries. Some users might also be annoyed at having to examine every track to make sure that all duplicates have been eliminated. This is especially difficult when the check boxes to remove tracks are so small. There should really be an easier way of mass selecting those files in need of removal.
Dupin is a handy tool to quickly find any duplicates in your iTunes libraries.
