I need to sort ripped audiobooks by disk
I used to be able to do this in previous versions of iTunes because, in the window, I could show "disk" and then just do an ascending sort. No I cannot find a way to show the disk number. This is an issue because I ripped David Copperfield (28 disks) and the titles of the tracks are "CD01 track 01,"CD02 track 01," etc. I sorts by track name and in that way, it will go through all the "track 01" in the book by disk order and then it goes to "track 02." This is not helpful. Can someone tell me how to do a sort by disk? Thanks
