Intranet File Access and Organization

Looking to purchase this plugin, but wanted to know if it would work for me. I am creating an intranet that will need to give access to certain files depending on login. Employees will have restricted access while managers will have much more access. This can be accomplished in most access plugins, but where I can not find something is in organizing it. I need also to be able to place files under categories on the page so it is not just on large list of files. They need to be under say Nursing or HR or Administrative so that they can easily be found. Can this plugin do that?
