BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a file control system, and more particularly to a file control system for updating a file in a plurality of terminals of a large-scale network online system.

[0002]

2. Description of the Related Art In a large-scale network online system, it is very important to always maintain the identity of a common file between a host device and each terminal. When changing the common file, the upper device and all terminals must be changed at the same time.

In the conventional file control system, file updating is manually performed for each terminal completely separately from the online system, or even when the online system is used, the file is unilaterally transmitted from the host device to the terminal. The file is updated manually on the terminal side.

[0004]

However, in the above-mentioned conventional example, since the file is updated manually on the terminal side, it is difficult to secure the manpower, and the number of man-hours including preparation is very large, and There is an inconvenience that an operation error and a work omission are likely to occur and it is difficult to update the files accurately and simultaneously for all terminals.

SUMMARY OF THE INVENTION The object of the present invention is to improve the inconvenience of the conventional example, and in particular, in a large-scale network online system, when a host device and a terminal are connected, the terminal can be automatically updated to the latest version. To provide a file control system.

[0006]

Therefore, in the present invention, in a file control system composed of a terminal and a terminal for transmitting and receiving a message via a network, when the terminal is connected to the network, the host apparatus is connected. The management information is received from the terminal, and when compared with the management information of the own terminal, if the management information is different, a function of requesting the transfer of the corresponding file to the higher-level device is provided. This aims to achieve the above-mentioned object.

[0007]

When the host device and the terminal are connected, the host device sends its management information to the terminal. When the terminal receives a message from the higher-level device, it analyzes the received message and determines that it is a management information message, and compares the management information of the higher-level device with the management information of its own terminal. As a result of the comparison, if they match, the user can use the terminal as it is as usual.
If they do not match as a result of comparison, the terminal user creates a file transmission request message according to the instruction from the user of the terminal, and transmits the file transmission request message to the host device. When the host device receives the file transmission request message from the terminal, it transmits the file to be updated by the terminal to the terminal. When the terminal receives the electronic message from the higher-level device, it analyzes the received electronic message, and if it determines that it is a file electronic message, it updates the file and management information.
