Abstract

In a hypertext wherein nodes are constituted by a plurality of files, a displayed node can be copied through a simple operation by providing the steps of accepting a request from a user for a copy of one of the nodes in said hypertext and storing the master file and the slave file that constitute the node for which a request for a copy has been accepted at said the copy request accepting step and storing file relationship information indicating the dependence between the master file and the slave file in addition to the master file when storing the master file.

accepting a request from a user for erasure of one of the nodes of said hypertext;

retrieving the stored master file that constitutes the node for which a request for erasure has been accepted at said erase request accepting step and retrieving said stored dependent slave file based on the file relationship information added to the retrieved master file; and

erasing the master file and slave file retrieved at said erased file retrieving step.

7. A method of processing a hypertext for copying at least one node of a hypertext having a plurality of nodes constituted by one master file and at least one slave file dependent on the master file and displaying at least one of the nodes of the copied hypertext, comprising the steps of:
