I need to setup users who only access certain group folders in read-only mode. No problem with that.
However, I also need those users not to be able to create any file by upload or create any folder in their home folder. Is this possible? And if yes, how can I do that?
Those users only need the files app and the search apps.
create a user with 0 B of disk amount. Share your “read only”-Folder with this user.
Edit: With sharing i mean, sharing by entering the username in the share-column of the folder to read only. There you can untick the boxes to reshare, edit and upload data, so there is read-only.
In the files app I see “You don’t have permission to upload or create files here” for users with 0 B disk amount. So also this is working.
