PURPOSE: A method for distributing files in a network is provided to distribute files in consideration of peer selection, selection for the size of a chunk file, bandwidth allocation and selection for a distributed tree. CONSTITUTION: A method for distributing files in a network comprises the following steps of: forming a plurality of spanning trees between a transmission(10) and receiving nodes(11,12,13); forming a minimum cost tree group through the sum of link costs of links constructing each spanning tree; controlling the transfer rate of each spanning tree which belongs to the minimum cost tree group according to the link cost of each spanning tree; and transmitting a chunk file through a spanning tree in which the transfer rate is adjusted.
