Abstract
Only the display device stores content files and a management device stores file management information. The content files are managed using the file management information. Because the management device does not store the actual content files, the security policy of an organization is not violated even if the management device is located outside the organization. Furthermore, because the display device stores the content files, the user desire to keep content files locally at hand is satisfied. Furthermore, because file management information consisting of small amounts of data is exchanged between the display system and the management device, the communication environment of the system does not need to be suitable to large data transmissions. Furthermore, because the management device stores the file management information, the storage capacity required by the management device is small.
