Abstract: In a case where the storage area of an information processing apparatus is insufficient for data to be downloaded, an information terminal causes the size of a lacking storage space and a list of stored data in the storage area to be displayed, and accepts, from a user, selection of the data targeted for deletion. If the selection is expected to resolve the lack of storage space, the information terminal accepts a deletion request and issues the deletion request to a management server to achieve deletion of the target data.
