I'm trying to find how to 'add' to my collection. I did an import from USB (which was labeled MUSIC), and now I have a folder on the hard drive called MUSIC, with all the albums from the initial import. All fine so far. Now, I want to add more albums to the MUSIC folder on the HDD. I load different albums on the USB, plug it into the car, select import and it creates a second folder on the HDD called MUSIC, and copies the new albums into there. How can I keep adding to the already created MUSIC folder? It's driving me nuts.
