PROBLEM TO BE SOLVED: To hierarchically manage all tasks using a computer cooperatively among plural users by expressing the relation of objects in the same directory with line segments. SOLUTION: A user can designate an object 10 being the start point and end point of a segment through the interface of a file manager 02 by algorithm. The data of segment objects can be preserved on a file system in the same way as the other objects in a data structure. Thus, the file manager 02 can display line segments 11 among the objects 10. A user can express dependency or sequence among each file on the file manager 02. Thus, a plane project in which the objects 10 are viewed as events can be prepared in the directory. |
