Delete iTunes U downloads without removing their reference I have many iTunes U videos that take a lot of space on my disk.
I don't really need them on my disk but I would like to keep their reference in my iTunes U library so I can re-download them when needed.

How can I do that?
Delete the videos. Then right-click on the course title and select Show all available items. This will restore the complete list of available episodes.



You can also do this by option-clicking on the disclosure arrow of the course. The arrow needs to be closed before option-clicking in order for this to work.
