Files in a workspace
Files in a workspace are private to that workspace. Only its members can open them, according to the Files app's permissions for their role, and a file link does not work for anyone outside the workspace.
Files are organized in folders and can be uploaded from your phone in any format. A file can also point to an item already in your Media Manager instead of being uploaded again, which is useful when the same logo is needed in several places.
Deleting files
Deleting an uploaded file removes it from the workspace. Deleting an entry that points to your Media Manager removes only the entry; the original stays in your Media Manager.
Anyone with delete permission on Files can delete any file, and the person who uploaded a file can always delete their own. The same applies to notes and calendar events.
Workspace files travel over encrypted connections and are stored encrypted. Access follows workspace roles: only members whose role allows it can open a file.
