Abstract
Abstract A scheme for transferring files from a file server to a file requesting client, which enables request and transfer of files which are related to a user requested file at a time of transferring a user requested file. The file requesting client makes a file request indicating a desired file, and in response the file server transfers a file list of files related to the desired file indicated by the file request. Then, the file requesting client makes a transfer request requesting a transfer of files according to the file list, and in response the file server transfers the files requested by the transfer equest. Alternatively, the file requesting client makes a request indicating a desired file, and in response the file server transfers a concatenated file formed by concatenating files related to the desired file indicated by the request. Then, the file requesting client extracts individual files from the concatenated file.
