In a system, in order to allow transfer of information relating to image data and the like to a desired directory in a directory structure in a host information processing apparatus, without performing an operation at the host information processing apparatus, in a first apparatus, a directory-information management unit acquires and manages directory information of a storage unit managed by a filing system of a second apparatus, and a display unit displays the directory information managed by the directory-information management unit. The user assigns a directory to which the image data and the like are to be transferred in the storage unit of the second apparatus, using an assignment unit.
