Abstract

PURPOSE:To prevent occurrence of the arranging mistakes by reading each available period information to decide whether the available periods of user files are expired or not and cutting those user files having the expired available periods. CONSTITUTION:Each user file 5 includes a production date information area 6 and an available period information area 7. The area 7 stores the available period information consisting of the periods to be held in the user files like one month, three months, etc. When a control program is executed, a CPU 2 reads the available period information out of the file 5 and decides whether the available period of the file 5 is expired or not. The expired files 5 detected are cut by the CPU 5 based on the instructions designated previously or the instructions which are properly received with operations of a keyboard 1. As a result, the user files easily and surely is controlled.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a user file management method for managing a plurality of user files stored in a user area provided on a disk, and in particular, a method for managing expiration dates of user files. It is something to do.

[Conventional technology]

FIG. 3 is a diagram showing an outline of a conventional user file management system. As shown in the figure, a disk 3 controlled by a computer 2 equipped with a keyboard 1 as an input means has t A knee fm area 4 is provided, and a plurality of user files 5 used by the user for desired purposes are stored in this user area 4.

At this time, usually in these user files 5, creation date information on which the file was created is stored in a predetermined creation date information area 6 for file management.

By the way, since the capacity of the disk 3 is generally fixed, the capacity of the user area 4 is also inevitably limited, and due to this capacity limitation, the number of user files 5 that can be stored in the user area 4 is also limited, and the number of user files 5 that can be stored in the user area 4 is also limited. Old user files 5 that have served their purpose need to be properly organized, and by organizing unnecessary files, new user files 5 can be stored and the user area 4 can be used effectively. .

Therefore, conventionally, the user file 5 stored in the user area
Management of whether or not the information is necessary is performed by the procedure shown in the flowchart of FIG.

That is, as shown in FIG. 4, the computer 2 reads the creation date information of each user file 5 stored in the user area 4, and a display device, etc. not shown in FIG. The creation date of is displayed together with the file name (step Sl).

Next, the operator calculates the period of existence of each user file 5 from the displayed creation date and current date of each user file 5 (Step S2), and selects each user file 5 in the retention period list created separately. In step s, the operator compares the period to be retained and the calculated actual period of existence to detect an expired user file 5 whose actual period of existence exceeds the period to be retained.
3).

The expired user file 5 is deleted or moved to another area by the computer 2 in accordance with a deletion command, a movement command, etc. given by the operator's operation of the keyboard 1 (step S4).

The user file 5 is managed through such a procedure, and this is repeated as appropriate or periodically.

[Problem to be solved by the invention]

As explained above, in the conventional user file management method, the operator must calculate the period of existence of each user file 5 and compare the calculated period of existence with the period to be retained, which is very time-consuming. This poses a problem in that the burden on the operator is heavy, and errors in organization, such as erroneously arranging user files 5 that have not expired, are likely to occur, making it impossible to easily and reliably manage user files.

This invention was made to solve the above-mentioned problems, and it greatly reduces the work the operator has to do, reduces the burden on the operator, prevents organization errors, and improves the management of user files. The purpose is to make it easy and reliable.

[Means to solve the problem]

A user file management method according to the present invention includes a user area released for users on a computer disk, and a user file management method for managing a plurality of user files stored in the user area. , stores expiration date information indicating the expiration date of each of the user files, reads each expiration date information by executing a management program by the computer, and determines the expiration date of each user file from the read previous expiration date information. determine whether or not the period has elapsed;
This system organizes the user files whose expiration date has passed.

[Effect]

In this invention, expiration date information stored in each user file along with creation date information is read, and from the read expiration date information, it is determined whether or not each user file has passed its expiration date, and A user file whose expiration date has passed is automatically detected, and there is no need for the operator to calculate the period of existence of the user file or to compare the calculated period of existence with the period to be retained, unlike in the past.

〔Example〕

FIG. 1 is a schematic diagram showing an embodiment of the user file management method according to the present invention, and numerals 1 to 6 indicate the same elements as in FIG.

Referring to FIG. 1, each user file 5 is provided with an expiration date information area 7, and this expiration date information area 7 contains expiration date information consisting of a period for which the user file should be retained, such as 1 month, 3 months, etc. By executing the management program, the expiration date information of each user file 5 is read by the computer 2, and it is determined whether each user file 5 has passed its expiration date.

Next, the procedure for managing and organizing the expiration dates of the user files 5 will be explained with reference to the flowchart shown in FIG.

Now, when the operator issues a command to execute the management program for the user file 5 by operating the keyboard 1, the computer 2 starts the management program (step 511), as shown in FIG. Each user file 5 stored in
creation date information and expiration date information are read (step 512).

Then, the computer 2 calculates the existence period of each user file 5 from the creation date and the current date of each user file 5 (step 513), and compares the calculated existence period with the read expiration date ( Step 51
4) It is determined whether the expiration date of each user file 5 has passed based on whether the existence period exceeds the expiration date, and so-called expired user files 5 whose expiration date has passed are detected (step 515).

At this time, for example, the creation date of a certain user file 5 is 7.
If it is September 1st and the current date is September 1st, the existence period is 2 months, and the expiration date information of this user file 5 is 1.
If a period of 1 month is stored, this means that this user file 5 has passed its expiration date.

Further, when an expired user file 5 is detected as described above, the computer 2 organizes the expired user file 5 according to a command given in advance or a command appropriately given by operating the keyboard 1.
A series of processing ends.

In this way, an expired user file 5 is automatically detected based on the expiration date information stored in each user file 5, so that the operator can calculate the existence period of the user file 5 and There is no need to compare the period of existence of the file with the period of time to be retained, the burden on the operator can be greatly reduced, and it is possible to prevent the operator from erroneously organizing user files 5 that have not expired.

In the above embodiment, a case has been described in which the management program is executed in response to an instruction from an operator, but the management program may be automatically executed at fixed intervals and the management of the user file 5 may be repeated periodically. Of course.

Further, as the expiration date information stored in each user file 5, a final date corresponding to the final date to be retained may be stored. In this case, it is not necessary to store creation date information in each user file 5. There isn't.

[Effects of the Invention] As described above, according to the present invention, each user file stored in the user area of the disk stores expiration date information together with creation date information. User files that have expired can be automatically detected, greatly reducing the burden on the operator by eliminating the work that the operator would have to do in the past, and preventing mistakes in organizing user files. This makes it possible to manage user files easily and reliably.
