- electronic document data that is available for use by a user;
usage location information indicating one or more usage locations in which use of the electronic document data is less restricted than in other locations; and

Abstract
A document file is configured to restrict, without a costly special-purpose terminal or the like, use of document data contained therein, if the document data is taken out of a predetermined location. A document file contains (i) electronic document data, (ii) usage location information indicating one or more usage locations in which use of the electronic document data is less restricted, and (ii) a data management program that causes, when a user requests use of the electronic document data, a computer to request for user location information indicating the current location of the user. Under control of the data management program, use of the electronic document data is permitted within a first usage pattern, if the user location is included in the usage locations. If not, use of the electronic document data is prohibited or permitted within a second usage pattern which is more restricted than the first usage pattern.
