I want to upload a PPT file and that should not be downloadable. I used to upload in Resources ->Files and added that file but that file is downloadable. Is there any way to upload a PPT file in moodle without download.I want to use for teaching resource so I don't want to use any video format files to upload.
No, this is not possible. This is not because of Moodle, it is because the way the web works.
