Thanks for the help, but my question is still unanswered, I want to know how to associate different file types with iTunes, maybe I am not asking the question correctly, or don't know the terminology. I know that my real player can be made to associate different file types from the tools menu, I check off the boxes with the different extensions, like, .mp3, wav, midi, .ogg, etc... I thought there was a feature like this on iTunes, but I can't find it, is it only available when I install it?
