I have been using iTunes for many years. I have a late-2013 iMac with 256GB internal SSD running Sierra 10.12.4. I don't use the internal storage for iTunes media. I have an external drive setup for that. Yesterday I noticed that when I click on "About this Mac" and go to storage, my internal drive shows 412GB of red iTunes almost taking up the whole bar. Now how could this be if I set the iTunes media folder location to my external? I double checked in iTunes preferences>advanced and it still shows my external as its source. What's strange is my internal shows 412Gb used up on the bar, but still says 216.34 GB free of 249.77 GB. This makes no sense to me. Anyone have any idea what this is about? Thanks
