Frustrated trying to manage duplicate music tracks on your Mac?
Of course you are!
The Show Duplicates feature is helpful but you still have to examine every single track and somehow decide whether you want to keep or delete the duplicates it might find.
Now there's Dupin. Your duplicate tracks manager. For macOS 10.15 and later only. (Dupin v2.14.1 for pre-macOS 10.15 is still available.)
With Dupin you can:
- Very quickly find all sets of duplicate Music tracks based on your choice of criteria
- Select the "Keeper" tracks from among a number of duplicates automatically using a variety of versatile filtering options
- Consolidate the play, skip, and ratings information from all tracks in a Dupe Group to the single "Keeper" track
- Re-populate playlists replacing "non-Keeper" tracks with "Keeper" tracks
- Remove duplicate tracks from Music and send files to the Trash
- Audition tracks with Quick Look
- Manage intentionally duplicated tracks
- Delete duplicate "dead" tracks
- Sort tracks and view track info
- Export a list of duplicates to a text file
- Locate tracks in the Finder and in iTunes
In addition, Dupin features:
- Compatibility with iCloud Music Library/Apple Music
- Support for Notifications
- Robust Documentation via the Help Menu
- Ample keyboard shortcuts
- Customizable toolbars
- Optional update checking
What reviewers say (about the older iTunes version):
- "Dupin [does] a much better job than iTunes' Show Duplicate Items command of finding and zapping duplicate files, letting you easily tame overflowing libraries."
- Jonathan Seff, Executive Editor, Macworld, "5 Essential Tools That Every iTunes User Should Have"
- "Dupin comes in so handy, and for $15 it's a small investment for your sanity."
- Dave Taylor, Mac Author, Ask Dave Taylor
- "Dupin does an excellent job finding all those pesky duplicates and removing them from your iTunes library."
- Roberto Baldwin, Mac|Life
- "The app performs well and comes with an accessible interface and excellent functionality. If you have a large iTunes library, you'll love it."
- Chris Page, Editor CNET's Download.com
- "If, like me, your iTunes library is an unholy mess, I'd suggest you give it a spin."
- Christopher Breen, Senior Editor, Macworld
