<P>PROBLEM TO BE SOLVED: To realize processing of file synchronization with less load and with high efficiency, by transmitting/receiving files only according to necessity when a file operation is conducted by a user. <P>SOLUTION: When a file operation is conducted by a user, a terminal device 1 generates an attribute group of the file and transmits a file operation notification to a storage server 3. The storage server 3 identifies a type of the file operation based on the received attribute group, generates a new FI and transmits it to the terminal device 1 where the file operation is conducted. The storage server 3 transmits an update notification to an event server 4 and the event server 4 transmits an event having an update to other terminal device 1 accessing a shared folder. Upon receiving a FI acquisition request from the other terminal device 1, the storage server 3 transmits the FIs of all the files belonging to the superior folder (including the new FI on the file to which the file operation is conducted) to the other terminal device 1. <P>COPYRIGHT: (C)2012,JPO&INPIT |
