<p>PROBLEM TO BE SOLVED: To increase the operability of retrieval and contents confirmation by making it possible to visually and easily confirm files and folders made hierarchical. SOLUTION: On a display screen, an artist list group 101, an album list group 102, and a contents (music in album) list group 103 are displayed. The respective groups 101 to 103 are displayed so as to form a three-dimensional body, e.g. flanks (polygonal cylinder) of a prism on a panel 101a, etc., on which an image showing the contents of a corresponding file or folder is pasted.</p> |
