Abstract
A method and a system for providing a file. The method of providing a file by using at least one server linked with a plurality of terminals through a network, the method includes: determining whether there exists a destination terminal which stores a requested specific video-on-demand (VOD) file by searching a database which stores a list of VOD files stored in the plurality of terminals, when a request terminal that is one of the plurality of terminals requests a specific VOD file to be transmitted; and transmitting access information of the destination terminal to the request terminal when there exists the destination terminal and transmitting the requested specific VOD file to the request terminal when there exists no destination terminal. Accordingly, a VOD content is directly transmitted among terminals under a control of a VOD server, when a VOD service is provided. Therefore, it is possible to remarkably reduce a load of the VOD server by reducing traffic which was concentrated on the VOD server in the past.
