I'm embarrassed to admit I don't understand how iTunes works despite having a mac for 6 years. How can I clean out my music folder (iTunes media) and then get iTunes to update? I've made substantial changes, so I don't mind just reloading the library if that's what I should do.
Also, I have a "music" folder which is not organized at all and doesn't seem to be affected by me deleting files in the iTunes media folder. Are these just copies of the songs in the iTunes media folder? Can I delete them?
Thank you for your help, and I apologize if the answer to this question is glaringly obvious.
