Begin creating Folders so you can organize your documents. Go to Document Manager and then select New Folder to create the top-level folders that you need. If your workspace already contains the folders, then simply select any folder or subfolder.

Now you can go to Folder Properties to allow / limit / close an access to the Folder for others or you can do it later whenever you want.

Folder Properties contain a General tab that allows you to view general folder information and a Security tab that allows you to view and/or change the level of access to the folder through the system of Folder Permissions.
