  Next, the number of expanded hierarchies, which is the maximum hierarchy of the directory tree to be printed, is designated (S102). Here, when the number of expansion layers is set to automatic setting expansion, the optimal number of expansion layers according to the size of the item is automatically determined. Next, the font size of the character string of the directory tree to be printed is designated (S103). Here, if the font size of the character string is set to the automatically set size, the optimum font size according to the size of the item is automatically determined.

  Next, the directory of the highest hierarchy or the write information is designated (S104). Here, when “<Disc>” is designated, the directory automatically becomes the highest layer of the write information. Here, the processing order of the above-described steps S101 to S104 may not be as described above as long as these four steps are executed before step S105.

  Next, based on the designated highest-level directory and the number of expanded hierarchies, it is determined whether or not the depth from the designated highest-level directory to the deepest level is deeper than the specified number of expanded hierarchies. (S105). If it is deeper than the specified number of expanded hierarchies (S105; Yes), the specified number of expanded hierarchies from the specified directory of the highest hierarchy based on the specified directory of the highest hierarchy and the number of expanded hierarchies. A directory tree in which the hierarchical expansion is expanded is generated (S106).

  On the other hand, if it is shallower than the specified number of expanded hierarchies (S105; No), the directory tree is expanded from the specified highest hierarchy directory to the deepest hierarchy based on the specified highest hierarchy directory. Is generated (S107).

  Next, the directory tree icon size is calculated based on the font size of the designated character string (S108). Here, it is calculated by multiplying the font size by a predetermined constant. This predetermined constant is usually a value around 1. Next, based on the calculated icon size, the designated font size, and the generated directory tree, image information of the directory tree is generated (S109). Here, the image information is information for display or information for printing.

  Next, the image information of the directory tree to be laid out is generated based on the image information of the generated directory tree and the size of the designated item (S110). Finally, based on the image information of the generated directory tree and the position of the designated item, the directory tree is laid out on the layout area (S111), and the process ends.
