Since the capacity of the storage device is limited, it is necessary to efficiently save the save file. Therefore, it is common practice to reduce the storage space by reducing the storage file.

However, it takes a longer time to retrieve a file that has been subjected to reduction processing from a storage device than a file that has not been reduced. Therefore, an operator who handles the electronic filing apparatus directly selects a file that is accessed less frequently or a file that does not give priority to shortening the extraction time, and performs reduction processing.

Further, the storage medium constituting the storage device has a different take-out time depending on the storage medium such as a hard disk, a magneto-optical disk, an optical disk or the like. Therefore, the operator switches the storage medium to be stored according to the extraction time required for the storage file, and if the priority of shortening the read time of the storage file changes, the storage file is moved between storage media and all the storage files are stored. Optimal take-out time,
I was trying to keep it at the file size.

However, there is a possibility that a problem may occur such that the file is reduced, or conversely the extraction time may be delayed, but the file size is reduced and the saved file for which space efficiency should be prioritized is not reduced.

The present invention has been made in view of the above circumstances, and provides an electronic filing apparatus capable of automatically storing a storage file in an optimum storage form without depending on the judgment of an operator. The purpose is to

Embodiments of the present invention will be described below. FIG. 1 is a diagram showing functional blocks of an electronic filing device according to an embodiment of the present invention. The electronic filing apparatus according to the present embodiment includes an electronic filing system body 1 including a CPU and an internal memory, a storage device 2 including a plurality of storage media, an input device 3 for processing an instruction input from an operator, and a printer. And an output device 4 such as a CRT.

The electronic filing system body 1 includes a condition value setting means 5, a condition value reading means 6, a storage place remaining amount checking means 7, a take-out time calculating means 8, a machining necessity judging means 9, a post-machining take-out time and a file size. Calculation time 10,
From the processing method determination means 11 and the processing means 12 to the CPU
And a condition value holding unit 13, a remaining amount data holding unit 14,
The storage information holding unit 15 and the post-processing storage information holding unit 16 constitute the internal memory.

The storage device 2 includes various storage media (eg, hard disk, hard disk, etc.) in which a plurality of storage files are stored.
The storage file holding unit 19 is composed of a magneto-optical disc, an optical disc, etc., and the condition holding unit 18 is constituted. The condition storage unit 18 stores the file names, file sizes, file types (text data, CAD data, etc.), storage methods (time priority, space priority, etc.), and status of all files stored in the storage file storage unit 19. It is composed of a table that records (processing method) and the presence or absence of the previous version.

Next, the operation of this embodiment configured as described above will be described. FIG. 3 is a flowchart showing the overall flow of the file storage form changing process. First, the condition value setting unit 5 sets the condition value and various parameters used in the process necessity determination and the process method determination described later in the condition value holding unit 13. In this setting process, the condition value setting means 5 is input from the input device 3 as shown in FIG.
The condition values shown in (a) to (f), storage space remaining amount, extraction time calculation parameter during compression, file size calculation parameter during compression, extraction time calculation parameter during difference,
Data such as extraction time calculation parameters for each storage medium
It is performed by saving the data in a predetermined address of the condition value holding unit 13.

Further, the storage location remaining amount checking means 7 collects the state of the storage space of the storage file holding unit 19 in the storage device 2 at a constant cycle and stores it in the remaining amount data holding unit 14.

When it is time to change the storage form of the stored files, initial processing is executed (S1). In the process of step S1, as shown in FIG. 4, the condition value reading means 6
Reads the data such as the condition value stored in the condition value holding unit 13 and inputs it to the processing necessity judging means 9. Upon receiving the condition value data, the processing necessity determination means 9 fetches the remaining amount data from the remaining amount data holding unit 14. Then, the processing necessity determination means 9 compares the condition value 3 (condition regarding the capacity of the storage location) of each storage file with the remaining amount data of each storage medium in which these storage files are stored, and changes the storage form. It is determined whether or not it is necessary (S2). For example,
When the capacity condition of the hard disk of the save file holding unit 19 is 80% and the remaining data of the hard disk is less than 20%, the optimum save mode is set for all the save files saved in the hard disk. consider.

In this embodiment, file compression (S3), differential processing from the previous version (S4), and movement of files between storage media (S5) are performed for each file whose storage mode is to be examined. consider.

In the processing of step S3, two types of compression, that is, compression with time priority and compression with space priority will be considered. The processing content in step S3 is shown in FIG. As shown in FIG. 5, the post-processing removal time and file size calculation means 10 reads the file size and type of the storage file from the table of the condition value holding unit 18. next,
The time taken to extract the file after the file compression is calculated by the equation (1), and the file size after the file compression is calculated by the equation (2). Extraction time after compression = (compression time parameter) x (file type time parameter) x (file size) (1) File size after compression = (compression size parameter) x (file type size parameter) x (file size) (2) The above equations (1) and (2) are calculated by changing the parameters for the compression method 1 of time priority and the compression method 2 of space priority. The calculation result is stored in the storage information storage unit 16 after processing.

In step S4, the post-processing take-out time and file size calculation means 10 fetches the necessary data from the condition value holding unit 18 and executes the processing shown in FIG. First, it is determined whether or not there is a previous version in the save file to be subtracted. If there is no previous version, the difference cannot be taken, so it is decided not to take the difference. If the previous version exists, it is determined whether the file type is text data. For other than text data, for example, C
Since high compression ratio cannot be expected even if the difference is taken in AD data etc., it is decided not to take the difference. In the case of text data, the size of the file after the difference is compared with the size of the file before the difference, and if the difference file size is larger, it is determined that the difference is not taken. on the other hand,
If the size of the difference file is smaller, the file extraction time after the difference is calculated by the formula (3), and the calculation result is stored in the processed storage information holding unit 16. Extraction time of difference file = {(difference file size) + (previous version file size)} × (difference time parameter) (3) In step S5, the post-processing extraction time and file size calculation unit 10 determines the condition value. Data regarding the storage file is fetched from the holding unit 18 and the size of the storage file is investigated. Then, the take-out time in different storage media is calculated by the equation (4).

Extraction time after movement = (storage medium parameter) × (file size) (4) The above formula (4) is calculated by changing the parameter for each storage medium constituting the storage file holding unit 19. It executes and saves the calculation result in the post-processing storage information holding unit 16.

When the examination of each storage form is completed as described above, a work method study work such as which storage form to change is carried out (S6). The processing content of step S6 is shown in FIG. In step S6, the take-out time calculating means 8 calculates the time t required to take out the save file in the current save state from the save medium parameter and the file size, and saves it in the save information holding unit 15. The processing method judging means 11 takes in data from the storage information holding unit 15 and the post-processing storage information holding unit 16, and further takes out the condition value 1 (Tmin: the minimum value of the allowable extraction time) and the condition value from the condition holding unit 13. 2 (Tmax: maximum value of allowable extraction time)
Take in.

When the take-out time t is less than the condition value 1 (Tmin), the storage method (time priority, space priority) is read from the table of the condition value holding unit 18. If the storage file storage method is time priority, the take-out time t ′ after the storage form is changed from the various storage forms examined in steps S3 to S5.
, T ′ <Tmin, and the storage mode with the shortest take-out time is selected. On the other hand, if time is not prioritized, t ′ <
One storage form or a plurality of combinations is selected at Tmin, which minimizes the file size. If the take-out time t is longer than the condition value 2 (Tmax), the reduction of the file size is given priority over the shortening of the take-out time, and the storage mode that minimizes the file size is selected. If the take-out time t is equal to or more than the condition value 1 and less than the condition value 2, the storage form is not changed.

When the storage mode selected by the processing method judging means 11 is notified to the processing means 12, the processing means 12 is processed.
The storage file is subjected to compression processing, differential processing, or file movement so that the storage mode selected in step 1 is selected.

After performing the above-mentioned work for all the storage files to be changed, the remaining amount of the storage location is read again from the storage information holding unit 15, and if the remaining amount is less than the condition value 3, the operator is informed. Notify and prompt to change the condition value.

As described above, according to the present embodiment, the necessity of processing the storage file is determined, various storage modes are examined, and then the optimum storage mode is determined according to time priority or space priority of the storage location. Since the storage form is determined by the above, it is possible to automatically determine the optimum storage form without depending on the judgment of the operator.

According to this embodiment, the take-out time t before changing the storage mode is compared with the condition value. If the take-out time t is shorter than the take-out time t'after changing the storage mode, the take-out time t'is the most. Since the storage form is changed to be smaller, the space of the storage place can be opened by the reduction process, and the take-out time is sufficiently short so that the experience time as before can be maintained.

According to this embodiment, the take-out time t before the change of the storage mode is compared with the condition value, and if the take-out time t is shorter than the take-out time t'after the change of the storage mode and the space is prioritized, Since the storage mode is changed so that the file size is the smallest within the range where the extraction time t ′ satisfies the condition value, the storage file can be made as small as possible while maintaining the extraction experience time.

According to the present embodiment, the take-out time t before changing the storage mode is compared with the condition value, and if the take-out time t is longer than the take-out time t'after changing the storage mode, the file size after the storage mode is changed. Since the storage mode with the smallest value is selected, a sufficient space for the storage location can be secured, and the feeling speed at the time of taking out is slow, and the feeling time as before can be maintained.

In the above description, the necessity of processing the storage mode is determined at regular intervals and the change processing is executed if necessary. However, when storing a new file, steps S1 to S6 shown in FIG. 3 are performed. You may make it perform the process of. In this case, since the processing method is always judged when a new storage file is generated, it is not necessary to judge the processing necessity. The present invention is not limited to the above embodiments, and various modifications can be made without departing from the gist of the present invention.
