I just sold my macbook pro and I moved my music to an external hard drive. everything is in the iTunes Media Folder. I then moved the iTunes media Folder to my NAS (Synology DS411j) Now I want itunes to know that my music library is on the NAS. When I import the files from the NAS it creates a playlist for each music folder that is on my NAS. How do I prevent iTunes from creating all these playlists?
