<p>PROBLEM TO BE SOLVED: To easily perform all of an upper hierarchical move, a lower hierarchical move and a horizontal hierarchical move by controlling three hierarchies which are upper and lower hierarchies one by one and include a display object hierarchy in all. SOLUTION: When a folder that becomes a display object is designated, a hierarchical information acquiring part 1D acquires child folder information or file information of a lower hierarchy that becomes a child of the designated folder, parent folder information of an upper hierarchy which becomes of a parent of the designated folder and folder information of the lower hierarchy including the designated folder that becomes a child of the parent folder. A base display control part 1A displays the acquired parent folder information as a base displaying part 14A, a sub-display controlling part 1B en bloc displays the lower hierarchical folder of the whole parent folders including the designated folder based on the acquired hierarchical information as a sub-displaying part 14B and a list display controlling part 1C displays the child folders and files as a list displaying part 14C in a list based on the acquired hierarchical information.</p> |
