Dave Taylor on Dupin
Dave Taylor is one of my favorite coding guys; he's got the know-how on everything from HTML to UNIX. So I was pretty bowled over to see Dave's take on Dupin v2.1 in a post on de-dupin' iTunes. Many thanks!
Dupin v2.1 Released
Dupin v2.1 is now available.
Dupin is your iTunes duplicates manager.
With Dupin you can:
- Very 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
- Consolidate the play, skip, and ratings information from all tracks in a Dupe Group to the single "Keeper" track
- Re-populate iTunes playlists replacing "non-Keeper" tracks with "Keeper" tracks
- 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
New in Dupin v2.1:
- runs under Snow Leopard or better only
- adds aproximate time matching for Time Criteria (settable to :01 ≤ n ≤ :10 seconds)
- adds File Path column to main table
- made task additions to contextual menus
- some warning dialogs now have suppression/reset options
- "Search" configurable with categories, re-located to toolbar
- other minor GUI improvements and alterations
- speed enhancements

Size of Files, Size of Library
It's not the size of your "iTunes Media" files that best describes how big your media file collection is. Often, querying Correspondents will report that their iTunes Media folder is so many GBs (or so many days-worth). But if that total includes a lot of video then the number of files is smaller than the same-sized folder containing just 128kbps audio files (eg: my "Star Trek" with Extras at 6GB+ is a little smaller than my "Compilations" folder which contains over a thousand files). Very few of my scripts and apps directly work on the files in the iTunes Media folder anyway, so in many cases its size is irrelevant; scripts work with tracks in iTunes, so the number of tracks is more important than the size of their files. A better relative measurement for comparison purposes is the size of your "iTunes Music Library.xml" file (located in ~/Music/iTunes). It has an entry for each track in your library and all (well, most) playlists. Therefore, the more tracks and playlists you have the larger the XML file will be.
