I would like to disable attachments for a space.

In my space (cloud) I would like to turn off attachment downloads. How can I do that?

I don't think you can prevent anyone from downloading an attachment that is already there. Short of deleting the attachment from Confluence.

If you don't want users to be able to upload attachments, just remove the Add Attachments Permission.

Thank you John.
Too bad for me...
