Provided is a technology of efficiently narrowing down files that may be deletable in a file server, and thus reducing the burden on a user in performing an operation of checking if any of the files are deletable. The technology includes displaying the size distribution/cumulative size of files in the file server, and selectively displaying, among the files in the file server, files that seem to have been carefully stored, files that are suspected to be stored in duplicate, or files that have, if deleted, a highly advantageous effect of reducing the used capacity of the file server. |
