Moving your iTunes Library
From Mac Guides
If you have a large iTunes Library or a small internal Hard Drive in your computer you may want to move some of your music to a different location on your machine.
The best way to do this is in iTunes itself.
- Open the iTunes Preferences (iTunes > Preferences)
- Go to the Advanced tab
- Change the iTunes Music Folder location
- Press OK
- Once it has finished processing go to the Advanced menu and choose Consolidate Library
- iTunes will copy all of your music to the new folder.
Note: this will change your music folder structure to the standard iTunes format.
