One of my biggest complaints about iTunes is that it doesn't monitor folders for new music. Well, after a little trial and error, here's a quick way to make iTunes scan a folder and add any songs that aren't currently in your music library.
- Run iTunes.
- Choose "File" > "Add To Library…"
- Browse and choose the folder you wish to scan
This will cause iTunes to scan the music folder, adding any new tracks that in the folder and subfolders without duplicating music that is already in your iTunes library.
Side note to Merrin: To use for your laptop, browse & select the Music folder on the network drive.
