PURPOSE:To shorten the transfer time of data between the terminal equipments. CONSTITUTION:A work station 12 designates a document file in an external storage 13 connected to a work station 11 and checks whether a document file having the same name as the designated one is included in an external storage 14 or not. If so, the control numbers added to the pages of the document file are compared with each other. Then, only the data having no coincidence among the page control numbers is transferred. The control number of each page is updated only when the contents of the relevant page of the document file are changed. Therefore such data on uncharged pages are not transferred out of the document file. |
