DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a file management method for a terminal device, and particularly to a file management system for a terminal device that manages files held in each of several terminal devices connected to a host computer through a line. Regarding management methods.

[Conventional technology]

Conventional file management methods for terminal devices can be broadly classified into two types: distributed management methods and centralized management methods.

In the distributed management system, a terminal administrator at each terminal device creates and changes files, and manages file creation information and file free space information of the file creation medium in each terminal device.

In addition, in the centralized management method, the terminal administrator in the operation management department of the host computer creates and changes files for all terminal devices, and updates the file creation information and file free space of the file creation media on all terminal devices. Manages information.

There is a drawback that.

In addition, even with the centralized management method, there are some things that are done on the terminal device side, and the host computer's operations management department cannot completely manage the file creation information and file free space information of the terminal device. A system in which a terminal administrator at a local terminal goes to the location of each terminal device to create or change a file on the terminal device, but is unable to create or change the file due to insufficient free space for the file. The problem is that operational confusion is likely to occur.

An object of the present invention is to automatically reflect the file creation information of a terminal device input on a host computer in the file of that terminal device, and to update the file creation information and file free space information for the file creation medium of each terminal device. To provide a file management method for a terminal device that allows both the host computer side and the terminal device side to freely create and change files in the terminal device by automatically checking the files as needed and managing them on the host computer. There is a particular thing.

(C) At each of the terminal devices, the terminal file maintenance program that has received the file creation information executes file creation processing on each file creation medium,
(D) The file management program, which has received the file creation completion information from each of the terminal devices in the host computer, returns file creation completion information to the host computer through the line; (E) When each file is created on the terminal device side, the terminal file maintenance program is updated by running the terminal file maintenance program. (F) The two-aisle management program, which is activated as necessary on the host computer, sequentially sends file management information requests to each of the terminal devices through the line. (G) Upon receiving the file management information request on each of the terminal devices, the terminal file maintenance program collects file creation information including files created on the terminal device side and file free space information from the file creation medium. (H) In the host computer, the file management program receives file creation information and file free space information from each of the terminal devices, and sends the file management program to the terminal file management table. It consists of updating file creation information and file free space information in .
