Consolidating your itunes library
If the problem is only moving everything inside the i Tunes folder to the external drive, a simple cut and paste would solve it. Nobody wants to re-fill hundreds (or thousands) of song information, re-assign all the ratings, re-paste all lyrics and re-hunt for the cover art.
The only thing that should be different after the move is the location.
Another point to remember: Even though the multimedia files are in the external drive, i Tunes stores the information about them in the i Tunes Library file in your local hard drive. With a larger empty space in your laptop’s internal hard drive, you are convinced that moving your multimedia collection out was a good idea.
But you also realize that bringing an external hard drive everywhere you go is a bit impractical.
There are lots of tools to help you delete duplicates, rename your files and update your artwork - but most clean-up tasks can be achieved within i Tunes without much hassle.
Because everyone's digital music collection is a mess!
