[Problem] The present invention attempts, using a terminal that does not have digital rights management (DRM) as a base, to generate encapsulated files from original files, by adding access rights thereto and encrypting the same, while ensuring not to leave unprocessed original files. [Solution] A file management system has an intranet having data storage means, an encapsulation server, and a user terminal that is capable of accessing the intranet and the encapsulation server. The user terminal has encapsulation request means that transmits an original file and access rights information to the encapsulation server and receives an encapsulated file, for which encapsulation has been completed. The user terminal has encapsulated file saving means that saves the encapsulated file in the data storage means, and automatic original file deletion means that deletes the original file upon saving of the encapsulated file. |
