TuneSpan — Your iTunes Library on Multiple Drives

By Random Applications

Open the Mac App Store to buy and download apps.


TuneSpan allows you to browse and span the media in your iTunes Library.

To "span" your media means to distribute the files in your iTunes Library across multiple drives.

"…the somewhat magical way that TuneSpan resolves the problem of having too much iTunes content makes this app a must-have for those with big media libraries."
- Macworld / TechHive


TuneSpan helps you easily move the media files (Music, Movies, etc.) in your iTunes Library to multiple drives, avoiding the pitfalls of moving files manually. TuneSpan lets you browse and keep track of media in your iTunes Library on all drives, whether they're connected or not, and makes it clear to you what is and isn't currently available to play in iTunes.


To select some tracks, drag anything from the browsing area and drop it into the blue gradient Spanning Queue. You can drag Playlists, Media Types, Genres, Artists, Albums, Tracks, and Locations. To view your selection and remove tracks, just click the Spanning Queue.

To choose the location to move your selected media to, click the Span Location area in the bottom middle of TuneSpan. Or, you can drag-and-drop a folder from Finder.


There are several reasons you may need TuneSpan:

• You're running out of space. You have a big iTunes Library on your internal drive and you want to move some (or all) of it to an external drive. TuneSpan helps you do this easily and seamlessly while cleaning up after itself and allowing you to always keep track of where everything is.

• You store a lot of Movies/TV Shows in iTunes and you want to re-organize your media (i.e., move all your videos to an external drive). With TuneSpan, you can easily select a whole Media Type and move the files wherever you choose, while continually being able to see where the files are, move them around again, or restore them easily.

• You need more space temporarily. TuneSpan offers a fast way to move gigabytes of files in your iTunes Library to free up space. Later, you can easily restore your files to their original locations while keeping your iTunes Library perfectly intact.

• You regularly add new Music, Movies, Podcasts, etc. With TuneSpan you can easily move older media (or media you don't listen to as much) to an external drive while keeping your default iTunes Media location the same. This way, new stuff goes where it should and there's always room for more.


The spanning process is simple. TuneSpan makes copies of your media files at the selected Span Location; none of your media files are ever deleted automatically. Once a file has been successfully copied, TuneSpan will set the new location in iTunes. That's the spanning process for a track; copy its file and update its location in iTunes. By default, in the selected Span Location, TuneSpan will organize your files into folders just like iTunes. But, you can customize the folder organization in TuneSpan. After tracks have been successfully spanned, you can choose to have TuneSpan move the original files to the Trash, and even check for empty folders and move those to the Trash to help keep your system tidy.

TuneSpan does not directly modify the iTunes Library, but uses Apple Events (AppleScript) to set track locations.

And, you can keep working, playing, or enjoying your music in iTunes while TunesSpan does its job.


Unfortunately, TuneSpan can't span files that aren't included in the readable XML iTunes Library file. TuneSpan has no access to the following files; they are left untouched and unchanged:

Mobile Apps, Rented Movies, Ring Tones, Text-Based Books, PDFs, iTunes LPs, and iTunes Extras

Also, for SD and HD versions of a video, only one at a time can be spanned (the one that's currently selected in iTunes).

There is also a rare bug in iTunes that seems to cause some video files to be unable to span.

Worth every penny and then some

TuneSpan isn’t the sort of app I use often, which is a good thing - it does what it’s supposed to do reliably and I rarely need to launch it again. I won’t go over the feature list, I just had to rave about the one feature I used (with complete success) just now - namely, to locate an entire swath of “missing files”. After replacing my external hard drive, I realized I had made the mistake of simply copying my previously spanned media to the new drive, without using TuneSpan to change the spanning location for the files. The result: neither iTunes nor TuneSpan could find the files in their respective library indexes.

It was my mistake, so it wasn’t like I could fault the software for the mess. But lo and behold, in the “File” menu of TuneSpan is this “Locate Missing Files” option. That sounded hopeful. I clicked it (expecting to get some sort of file browser from where I would be expected to locate some or all of the missing files), and was taken immediately to the TuneSpan progress view, where I watched the app effortlessy breaze through my attached drives, locate the files, update and reload the iTunes library, and cheerfully announce that “All 647 files have been located!”

To which I replied: “How do I buy you all over again?”

MUCH Happier with iTunes Now!

I have to say, as far as bang for the buck, TuneSpan has to be in my top 5 apps now. For $15, it's a steal.

Besides taking the pain out of using an external iTunes folder, it really excels at keeping that folder clean. It matches the iTunes xml against the actual content of the folder, so if iTunes leaves any files behind when you delete, TuneSpan finds them and asks you what to do with them. And it is selective - you can leave some files in the default iTunes lib on your hd, or you can span them to the main repository, without any real brainsweat or time. (Even if you don't want an external repository, just keeping your iTunes lib clean is worth the price.)

So now I have some of my audiobooks on the hd - the ones I can d/l from audible if I delete them locally. Then I've got audiobooks that I've ripped from disk, or that I've d/l from somewhere, and don't want to go thru the pain of recreating them, so they go on the external drive and get backed up locally. And all of that is transparent to me. Try doing that with iTunes and not kirking out on your machine.

On the down side, it isn't a plugin for iTunes, and it should be. If you could span from inside iTunes, that would be worth big money. Thus 4 rather than 5 stars. Actually, I give it a 4.75.

Great software—especially for my SONOS library

This software has proved to be worth every penny. I recently bought a SONOS sound system, which — after the fact — I discovered has a 65,000 track limit for its library. My iTunes library has many more tracks than that, so I had been copying tracks into a separate library just for SONOS. Now with TuneSpan, I’m able to continue to have a unified library within iTunes, but have a separately indexed library for SONOS without needing to keep around two separate copies of each track. TuneSpan is a well-thought-out product, with good error correction built in to safeguard your metadata.

The developer’s customer service is also awesome. I had a small problem last night and sent a message to the developer. He replied in about a half hour with a specific answer as to how to proceed to solve the problem. He also asked me to follow up with him after I tried his solution (which worked!)

I recommend TuneSpan without hesitation.
