Want to get rid of all those annoying duplicate files you have in iTunes?
Dupin aims to help you via an easy to use iTunes style interface which 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 find duplicates in libraries from other users.
In terms of performance, Dupin can be a bit slow at times, and we found that it could slow down iTunes if it was opened up at the same time. When searching for duplicates in smart playlists Dupin is also not as effective as in normal libraries.
Finally some users might be annoyed at having to examine every track to make sure that all duplicates have been eliminated. This is especially difficult when the checkboxes to remove tracks are so small and there should be an easier way of mass selecting those files in need of removal. The latest version of Dupin also only works with Intel Macs and not PPC Macs.
Overall however, Dupin is a handy tool to quickly find any duplicates in your iTunes libraries.
