How do I move a music collection Sorry for what must be a very simple question but how would I move all the tunes I have on my laptop to an external drive connected to the laptop.  Storage has become an issue and the laptop is quickly running out of space so I want to put all my tunes on an external and free up some space.  This would not be for a backup but to free up space.
This is pretty straighforward, the steps are essentially:


Open iTunes and consolidate your existing library (File > Library > Organise Library)
Quit iTunes
Copy your ~/Music/iTunes folder to the external drive
Open iTunes while holding down the Alt key, which will prompt you to select the new library
When you're sure it's working, delete your original library.
