"[Does] a much better job than iTunes’ Show Duplicate Items command of finding and zapping duplicate files, letting you easily tame overflowing libraries." - Macworld, "5 Essential Tools That Every iTunes User Should Have"

Quickly find, filter, and Trash your iTunes duplicate tracks. Delete "dead" track duplicates. Handles iTunes Match tracks in the cloud. Dupin Lite is your iTunes duplicates manager.

Dupin Lite handles your duplicate tracks in 3 simple steps:

1. Get Duplicates - gather your duplicate tracks into Dupe Groups based on your choice of criteria. Case-sensitivity/insensitivity and "fuzzy" time matching can identify near-dupes.

2. Filter - automatically designate the single "Keeper" track in each Dupe Group using a variety of versatile filtering options (Most/Least Played, Oldest/Newest Added, Highest/Lowest Bit Rate, and much more)

3. Purge - remove the "non-Keeper" tracks from iTunes and optionally move their files to the Trash*

Additional Dupin Lite features:

• Works with iTunes Match tracks in the cloud*
• Support for Notifications
• Audition tracks via QuickLook
• Delete "dead" tracks
• Toggle case-sensitivity during duplicates search

Review by jzyjohn

Incredible Software - I recently changed my iTunes library location from an external hard drive to a Drobo, and inadvertently duped my music library. Dupin Lite found and cleaned up 30,500 duplicated tracks (approx. 300gbs) within a total of 30 minutes! There's no way I could have done that by hand.

Version 1.1.2
Review by Vanaguy

Non Functional - Dupin Lite generated a list of duplicate files, which is something that iTunes can also do. However, Dupin Lite's "Filter" command simply did not work. It did nothing. The list was left unchanged, unfiltered. Considering the entire point of this program is to filter and remove duplicates, It was a complete waste of money.
