Files shared to me take up space in my Dropbox. I cannot delete individual files, just unsubscribe from the folder. My Dropbox is now completely full of files shared to me. I do not want to unsubscribe from the folder, just delete some shared files to make space.
Alternatively, it has been suggested that the sender share files to me with a view only designation. This is unworkable as the recipient has no control over what the sender does. So if view only is the solution, then the recipient needs to be able to designation folders as view only, not just the sender.
