Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system file history management system and a recording medium storing the same, and more particularly to a system file history management system capable of recording system management data updated from a system file in a history file. And its recording medium.

[0002]

2. Description of the Related Art In a conventional system file history management system, as shown in FIG. 5, a computer 500 which operates under program control, a means 501 for executing an application setup program, and a means 502 for copying an application execution file. A unit 503 for storing a system file, a unit 504 for setting system management data in the system file, a unit 505 for determining that the system file has been updated, and a unit 506 for deleting the system file before the update. It comprises means 507 for recording the stored system file name in the history file, and means 508 for displaying the history file.

The operation of the conventional system file history management system having such a configuration will be described with reference to FIG.

Referring to FIG. 6, first, an application setup program is executed (step C).
1) After the execution file of the application is copied (step C2), the system file is stored before being updated (step C3).

Next, system management data is set in the system file (step C4), and it is determined whether the system file has been updated (step C4).
5).

If it is determined that the system management file has not been updated, the system file before update is deleted (step C6). If the system file has been updated, the stored system file name is stored in the history. When the file is recorded in a file (step C7) and the update history of the system file is referred to, the history file is displayed (step C8).

As described above, when an application is set up or deleted, a computer is added by adding, modifying, or deleting system management data in a system file in addition to copying or deleting an executable file. You can set system configuration information,
When system management data changed, the entire system file was saved.

[0008]

The above-described conventional system file history management system has the following problems.

A first problem is that the contents of change of the system file cannot be specified from the history file. The only way to identify the changes is to compare the latest system file with the saved system file.

[0010] The reason is that the updated system management data is not recorded in the history file but the updated system file name is recorded.

The second problem is that the number of stored system files before updating increases, and a large capacity of a recording medium is required.

The reason for this is that the updated system management data is extracted from the system file and the entire system file is recorded instead of recording the system management data in the history file.

An object of the present invention is to provide a system file history management system capable of extracting only updated system management data from a system file and recording it in a history file.
