Abstract
This invention provides a file control system which can reflect updated data in files of both a personal computer and portable information terminal, when data has been updated in one or both of them. This system is a file control system which has a personal computer apparatus and portable information terminal apparatus which can independently modify or edit data, and a connection means for connecting these apparatuses, and generates FILE-A.wlf for associating FILE-A.xls stored in the personal computer apparatus with FILE-A.pig stored in the portable information terminal. Data modifications in the associated files FILE-A.xls and FILE-A.pig are detected, and the detection result is reflected in FILE-A.wlf (third file). Data of both files FILE-A.xls and FILE-A.pig are matched on the basis of FILE-A.wlf in which the detection result is reflected. Furthermore, calculation formulas embedded in FILE-A.xls are applied to the updated data of FILE-A.xls to further update FILE-A.xls.
