If you have already delivered a presentation or video in class, it is better to make it unavailable than remove it.
NOTE: Removing content also removes any student notes or bookmarks, as well as class Q&A and all analytics associated with the item.
Removing an item removes it from the class, but the content itself remains in your library and can be published again to a section, or shared with an individual.
You cannot remove content that was published to the class by another instructor. You also cannot remove appliance-generated videos (captures of the lecture) for the class. You can make these items unavailable for student viewing as needed.
