Disclosed is a method for forming such a virtual network storage with use of general network storages and through the processings by a network storage accessing protocol without using any of dedicated network storages, concentrated management servers, and distributed directories, wherein the virtual network storage, when receiving a READDIR request from a client in step 301, transfers the received READDIR request to each network storage in step 302, then receives READDIR responses from the network storages. The virtual network storage then combines the READDIR responses from the network storages and sends the result to the client. This solves problems that increasing the number of network storages causes a centralized management server to become a bottleneck that would hinder the improvement of the system scalability and using dedicated network storages disables employment of existing network storages for forming such a virtual network storage.
