You are responsible for creating a shared file system to support a new branch office. The manager has requested shared locations for branch staff to access the files. An area is required for all staff to access common forms and notices. Staff members are required to have read-only access to this location, but the manager requires full access to all content. A different area is required for all staff to share files without restrictions. The last area required is for the manager’s private files, and only the manager has access to this location.
