Consolidating itunes library on external hard drive
Before we do any moving of data, we first have to check to make sure everything is properly stored locally.
Open i Tunes and click on i Tunes – Preferences in the navigation bar in OS X or on the small icon at the top left in Windows.
The original files are left in their original locations.
Visit Stack Exchange Note: After you click OK, i Tunes copies any files that are added that weren't already in the i Tunes Media folder and places the copies in the folder.
Did you know it was possible to move your i Tunes library over to an external hard drive?
If you’re low on space and you have a lot of media that simply cannot be stored using i Cloud, then one great option is to move everything to an external USB drive.
If all went well, i Tunes should load with your entire library enact!
You should be able to see all your media files and play them.
