Frustrated trying to manage your duplicate tracks and files in iTunes? Of course you are!

iTunes' "Show Duplicates" feature is helpful but you still have to examine every track to determine whether you want to keep or delete the tracks it finds. Smart Playlists are of dubious help and trying to locate all duplicates with them can be tedious as they can quickly crowd your Source list and slow iTunes down.

Now there's Dupin.

Dupin is your iTunes duplicates manager.

With Dupin you can:

  • Quickly find all sets of duplicate iTunes 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
  • Purge duplicate tracks from iTunes and send files to the Trash
  • Manage intentionally duplicated tracks
  • Copy tracks to new iTunes playlists
  • View duplicates in non-loaded libraries created with iTunes' multiple library feature or iTunes Library Manager
  • View duplicates in iTunes libraries on other machines on your local network
  • Sort tracks and view track info
  • Export a list of duplicates to a text file
  • Locate tracks in the Finder and in iTunes
  • Audition tracks

In addition, Dupin features:

  • Familiar iTunes-like interface
  • Robust Help
  • Ample keyboard shortcuts
  • Visual progress feedback during operations
  • Customizable toolbars
  • Optional update checking

Dupin is easy to configure and use. Download the full-featured demo and try it out for yourself now.

This update is free for registered users.

The unregistered demo version of Dupin will display up to 20 sets of duplicate tracks per session.

The full version of Dupin costs $15.00. After your payment is received you will receive a registration code which will enable Dupin to display all the duplicates it finds. You'll also enable me to continue working on Dupin and make it work better for you!

You can make safe and secure payments using your credit card. Just click either the "Kagi" or the "PayPal" button below.

Make payments through Kagi

PayPal users: Payments made by PayPal eCheck will take up to 5 business days to clear. As soon as your eCheck clears with PayPal your registration code will be emailed to you. (Your payment will be by eCheck if you do not have a credit card attached to your PayPal account or your PayPal account is "unverified".)

Currently, I can only accept payments electronically via PayPal and Kagi. For other payment options, please email me at dougscripts at mac dot com.

Yahoo mail users: There is a very good chance Yahoo will re-route emails from me to your spam or junk mailbox. As soon as you receive the PayPal confirmation, check these mailboxes for the email containing your registration code. Otherwise, if you don't receive your code, let me know; it may take me a day or two to manually send you a code.
