I would like to sort my iTunes library according to the login that was used to purchase the file at the iTunes store.
I purchased a few items a few years ago on a login that I have long since forgotten. I have tried the Apple password reminder feature, but none of the emails that I thought were plausible accounts I had used to create my iTunes account were registered in iTunes.
Every time I try to move my library, those few files purchased in the old login give me headaches. I would like to delete the files from my library permanently, but I need a way to sort them out.
