You can give other users access to your folders by assigning roles to them. For example, anyone who wants to review and mark the items in a folder must have the Review role in that folder. Other roles permit users to export items from the folder and search for new items to add to it. The Full Control role combines all these permissions in one role.
You must have the Role Assignment permission in the folder to give other users access to it. By default, users with the Folder Full Control role have this permission.
