Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a file management processing apparatus, and more particularly to a file management processing apparatus capable of efficiently deleting a file shared by a plurality of users.

[0002]

2. Description of the Related Art A system in which a plurality of users share various files handled by a computer is well known. FIG. 5 is a diagram showing a system that uses files from a plurality of terminal devices (hereinafter referred to as terminals) as an example of a system that uses such a shared file.

In FIG. 5, the system has terminals Ti (i = 1, 1,
2, 3, ..., N), a file processing unit 60, a system console 69, and a file device 2 having files F1, F2, F3, ..., Fi (hereinafter referred to as file Fi). The file processing unit 60 has a communication control unit 33, a file control unit 61, a file register 65, and a file deletion utility 66.

The terminal Ti is connected to the file processing unit 60 via the communication line 38, and the user of the file Fi stored in the file device 2 (for example, the program of the terminal Ti that reads / writes the file Fi) is File processing unit 60 from terminal Ti
To the file access request to the file Fi.

The transmitted access request is input to the file control unit 61 via the communication control unit 33, and the file control unit 61 starts file access processing. The file control unit 61 inputs the user identification name and password, if necessary, based on the management information (file name, user password, etc.) necessary to access the file Fi stored in the file directory 65. Is requested to confirm the user and the usage qualification of the file of the user, and then the file Fi of the file device 2 is accessed.

The management of accessed files will be described. The user of the file Fi is managed by the system so that only the owner of the file Fi can access it. However, when using the file of his own with other people (users other than himself) , Is registered in the file register 65 as a shared file, and only a predetermined user is allowed to access the file Fi.

FIG. 6 shows an explanatory view of the file directory. In FIG. 6, the file Fi used from the terminal Ti is the storage area information of the file for each file name (FLi), the password information for checking the access right to the file, and the case of permitting the use of the file to another person. User information and the like are stored in the file register as file management information.

For example, the file F1 (file name FL1),
The file F3 (file name FL3) is permitted to be used only by the users who can input the passwords P1 and P2 respectively, and the file F2 (file name FL2) is a user who has the user identification name = A as user information. Then, each user having the user identification information = B is allowed to use the file F2. Similarly, the file Fj (file name FLj) is permitted to be used by users having user information A, B, C, ....

Registration of these pieces of information in the file register is performed, for example, by the system administrator inputting a predetermined command from the system console 69. Next, a case will be described in which the file Fj (file name FLj) shared by the users and used is deleted from the terminal Ti.

The system administrator is required to identify the user identification names A, B,
Inquire all users who have C, ... about the use of the file Fj (for example, round-trip letter, telephone confirmation, etc.),
Make a decision to delete the file.

When the file deletion is decided, the system administrator selects the file name FLj from the system console 69, for example.
The file deletion utility 66 is started by inputting a file deletion command with parameter as a parameter, and the file deletion utility 66 deletes the specified file Fj from the file device 2 and also deletes the file name FLj from the file register.
Delete the registration for.

[0012]

To delete a shared file used by a plurality of users, the system administrator inquires of all users of the shared file whether or not the file can be deleted, and the agreement of all the users is obtained. After that, the system administrator was deleting the file.

Even if a shared file is no longer used by all users, it is not deleted until the system administrator inquires of the user and the file device is occupied and the efficiency of use of the resources of the computer system is reduced. There was a problem of coming.

It is an object of the present invention to delete the shared file and release the file area for other purposes when all users are no longer using the shared file to improve the efficiency of use of system resources. To do.

[0015]

FIG. 1 is a block diagram showing the configuration of the present invention. The figure shows a file management processing apparatus in which the file processing unit 30 receives requests from a plurality of users and performs file management processing in accordance with the requests.

The file management processing device is provided with a file user registration unit 35 and a file deletion processing unit 31, and the file user registration unit 35 provides the file identification information and the file for each required file. Register the user identification names of all the users who share the information.

The file deletion processing unit 31 receives the file deletion request of the user from the file processing unit 30, and when the file deletion request specifies the file registered in the file user registration unit 35. When the requester's user identification name registered for the file is deleted from the file user registration unit 35, and all the user identification names registered for the file are deleted. Causes the file processing unit 30 to delete the file.

[0018]

When the file deletion processing unit 31 receives the file deletion request, the file deletion processing unit 31 checks whether or not the identification information of the user is registered in the file user registration unit 35. , The user's user identification name is deleted, and when all the user identification names are deleted from the registration of the file in the file user registration unit 35, the file is deleted from the system so that the user can You can avoid the situation where unused files occupy system resources forever.

[0019]

FIG. 2 is a block diagram showing an embodiment of the present invention. The system shown in FIG. 2 has terminals Ti (i = 1,2,3, ...,
n), the communication line 38, the file processing unit 30, the system console 69, the file deletion processing unit 31, the file user registration unit 35, and the file device 2. Files F1, F2, F3, ..., Fi (hereinafter referred to as file Fi) The file device 2 has files F1, F2, F3, ..., Fi that the user of the terminal device 1-i accesses.

The file processing unit 30 has a communication control unit 33, a file control unit 36, a file register 65, and a file deletion utility 38, and receives a request from a terminal Ti connected via the communication line 38. Based on the read / write processing of the file device 2 and other file management processing,
Except for the matters described below, it has the same functions as the communication control unit 33, the file control unit 61, the file register 65, and the file deletion utility 66 of the conventional file processing unit 60 in FIG.

Access processing of the file Fi from the terminal Ti. The terminal Ti sends an access request to the file Fi to the file processing unit 30 via the communication line 38, and the file processing unit 30 processes the access request in the same manner as the file processing unit 60.

Next, a process for deleting the file Fj (file name FLj) shared and used by the users from the terminal Ti. In order to manage the deletion of the shared file Fj used by the user, the file user identification information is generated in advance in the file user registration unit 35 as the user information of the shared file in FIG.

The user information of the file user registration unit 35 is activated by the table creation unit 37 when the system administrator registers the user in the file register 65 from the system console 69 as in the conventional case. Then, the table creating unit 37 extracts and creates the user information for each file name recorded in the file register 65.

The shared file deletion processing procedure according to the embodiment shown in FIG. 4 will be described below. The user who no longer needs to use the shared file issues a file deletion request to the file processing unit 30 from the terminal Ti, and the processing step 80
File name (FLj) and user identification name (user A
The file deletion command specifying i) as a parameter is received by the communication control unit 33 of the file processing unit 30.

Therefore, the communication control unit 33, in the processing step 81,
The received file deletion command is identified, the file deletion processing unit 31 is activated, and the command is passed. The file deletion processing unit 31 searches the file user registration unit 35 by the file name specified by the command in processing step 82, and the corresponding file name is searched in the processing step 83 by the file user registration unit 35.
Identify if it was registered in.

As a result, if there is no designated file name in the file user registration section 35, it is determined that the file is not a shared file, and a processing step for performing normal file deletion processing is performed.
The file deletion utility 38 is activated at 84 and the file deletion command is passed.

In step 85, the file deletion utility 38 executes the system console in the conventional system.
File deletion utility 66 by command from 69
After executing the file deletion process, the communication control unit 33 passes the notification of the processing result addressed to the requesting terminal Ti to the communication control unit 33 in the processing step 86. A processing result notification is sent to and the processing of this command ends.

The file deletion processing section 31 executes the processing step 83.
When the file user registration unit 35 identifies that the specified file name is present, the process step 87 identifies whether the file identification requesting user identification name is registered in the file section.

As a result, if the user identification name (user Ai) is registered, the user identification name (user Ai) of the file item from the shared file user registration unit 35 is processed in step 88. Is deleted, and in the processing step 89, it is identified whether the user registration of the file remains after the deletion.

If the registration of the user identification name still remains, the file deletion processing section 31 determines the terminal at processing step 90.
Since the deletion processing end notification addressed to Ti is passed to the communication control unit 33, the communication control unit 33 sends a notification to the designated terminal Ti in processing step 91 and ends the processing of this command.

When it is identified in the processing step 89 that the registration of the user identification name still remains, the file deletion processing section
In step 31, the file deletion utility 38 is activated in the processing step 84 to pass the file deletion command, so that the processing steps 85, 86 and 91 are executed in the same manner as described above to delete the file.

The file deletion processing unit 31 executes processing step 87.
Then, if it is determined that the user identification name of the file deletion request source is not registered, an error notification is sent to the terminal Ti at the processing step 92, and the communication control section 33 receives the error notification. At 91, a notification is sent to the designated terminal Ti, and the processing of this command ends.

In the above description of the embodiment, the file user registration unit 35 is used as information only for managing deletion of shared files, but a file user registration unit 35 can also be used for a file dedicated to a single user. It may be registered in 35 (thus, in this case, only one user identification name is registered from the beginning) so that deletion processing of shared files and dedicated files can be handled uniformly.

In the above example, the file user registration unit 35
Was described as being separate from the file directory 65,
It is clear from the explanatory views of FIGS. 3 and 6 that both can be configured as integrated registration information so that the information of both is not duplicated.

[0035]

As is apparent from the above description, according to the present invention, when all users have stopped using the shared file, the shared file is immediately deleted and occupied by the shared file. By releasing system resources,
There is a remarkable industrial effect that the use efficiency of system resources can be improved.
