Why would you want to disable the download of a file.

The file plugin is made to share files, so it would seam dumb to disable the download of the shared file.

Teachers want to disable the download option of some files like audio,video files . They want students to only view these files . So the teacher want to disable download of some files , not all . Please help .

it's not possible in the core Files plugin. You could develop a plugin that adds an option on the file form to control if download is available.

If disabled, don't register (or remove) the download button.

This requires some development, but it can be done.

I believe that disabling the download of image files, audio files or video files is actually useless because if the user can access and view these files, they can always obtain a copy of an image (screenshot), a copy of a video (screen recording) or a copy of an audio (audio recording).
