I put many presentations up on Moodle for my classes. I currently just upload a .ppt presentation via file. Some have been donated to me by industry professionals and I would like to find out if there is an option in Moodle that will allow me to lock those presentations so that they can be viewed but the entire file can not be downloaded? I understand that they could always be printed/saved via screen shot but that makes the process quite a bit harder than just downloading the file and saving it to your hard drive.
Any advice would be appreciated.
