Guide to Move Music and Apps on to an External Drive

Published on by Acer AS07B41 Laptop Battery


Many Macs now come with SSD (solid State) drives as an option. They are fast, but the downside is that the storage capacity is typically much less than what you’d get from a traditional spinning HDD.


Aside from just being a good idea in general, because you can back up your data, it’s nice to move stuff onto an external when you travel or need the extra space for a while. Here’s how it’s done:


1) Locate your music folder in Finder. By default, there is a shortcut under the “Favorites” on the sidebar of the Finder window. Check if your Mobile Application folder is also in there (below, you can see that our iTunes Media, under Music, also contains our Mobile Applications and other iTunes files):

2) Copy your Music folder to an external drive by dragging the folder into it.


3) Go to iTunes preferences>Advanced. (as shown in the next two images)




4) Change location of your Music folder to the Music folder on the external drive. (shown above, under the Advanced Preferences) If your Mobile Applications folder is part of this. You’re done. If not, go through the rest of the steps.


IMPORTANT: If you plan to delete the music folder from your main drive because you are freeing up space, make sure that everything transferred correctly. This goes double for music, because it’s much harder to replace lost songs than it is to simply re-download an app.

5) Older versions of iTunes had the Mobile Applications folder outside the music directory. This may mean that the folder will be outside that Music folder.


6) Go to Organize Library:



7) Under those settings, check off both options (consolidate files and reorganize files in the folder “iTunes music”). Click OK. This may take a while depending on the size of the folder.



As an additional precaution: We realized that this did not work the first time. This was just us, and may not happen to you. That said, we’re glad it did, so we could troubleshoot this problem as well.


Here’s how to check:

1) Launch iTunes.

2) Go to Apps.

3) Right-click on any App and select” show in finder”

4) if the App shows up on your external drive, you are done. If it does not, repeat step seven above.

5) Again, check if it copied properly.


Almost Done!

All that’s left to do is verify that your Apps and music were correctly copied into the external drive. In our case we were able to free up more than 80 gigs of space. Remember to move your iTunes backups to external drive.The stuff below should be in your external drive.
