Directed iTunes to external drive, do I have 2 copies?
Finally, Seagate drive was not showing up until I downloaded a new driver to fix El Capitan issues. Now I am directing iTunes to my external drive. Where do I look to make sure I don't have identical files on my iMac? It used to be easy before, but now when I look for iTune files, it only shows the iTunes program. I don't want iTunes on my iMac because I have too much music.
iMac (21.5-inch Mid 2011), Mac OS X (10.7.5)
