Copy your iTunes folder (Music->iTunes) onto the external
Then open up iTunes, go to iTunes->Preferences->Advanced, under iTunes Music folder location, change to appropriate spot
Thanks! So can I copy it over, then delete the "Music" folder from the laptop HD, THEN go to preference->Advanced to set it up again? Will deleting the entire "Music" folder from the laptop HD be okay with itunes?
Obviously close iTunes when doing all this moving. You can delete after you follow my steps, just to make sure.
Thanks for taking the time to answer these questions. While itunes was closed the folder was moved to the external HD and I deleted the original folder. In the "Advanced" option, I changed the itunes folder location to the external drive, but after I did that, the library isn't being filled with the music. Any ideas?
