A file security system of the organization operates to protect the files of the organization and thus prevents or limits external users from accessing internal documents. Although the external users are unaffiliated with the organization (i.e., not employees or contractors), the external users often have working relationships with internal users. These working relationships (also referred to herein as partner relationships) often present the need for file (document) exchange. According to one aspect, external users having working relationships with internal users are able to be given limited user privileges within the file security system, such that restricted file (document) exchange is permitted between such internal and external users.
