File server for extracting and displaying file list on client, method of providing display on client, and computer program executable on file server

摘要

A file server for displaying, on a client, files to be retrieved, a method of providing a display on the client, and a computer program product with program instructions executable on the file server. The number of files to be displayed and start point information related to the start point of a file list to be extracted is acquired from a client, and a file list is extracted from files stored as a partitioned data set in a storage device based on the number of files and start point information acquired. The numbers of preceding and succeeding files stored before and behind the extracted file list are calculated, the calculated numbers of the preceding and succeeding files and the extracted file list are sent to the client. The client displays the file list and the received numbers of remaining files before and behind the received file list, respectively.
