Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of selecting a file for reading and writing a file recorded in a storage device of a computer at high speed, and a method of automatically creating a backup of an updated or newly created file. It is a thing.

[0002]

2. Description of the Related Art A computer has both a storage device having a relatively high read / write speed (hereinafter referred to as a high speed device) and a storage device having a relatively low read / write speed (hereinafter referred to as a low speed device). In this case, rather than directly reading and writing the file on the low-speed device, it is better to transfer the file to the high-speed device once and then read and write the file on the high-speed device again for the entire time required for reading and writing. Can often be shortened as To use this characteristic (hereinafter referred to as characteristic 1), 1. Select which file on the low-speed device is to be read or written. 2. Transfer selected files to the high speed device. 3. If the selected file is a data file, another program for processing the data file (hereinafter referred to as program 2) is loaded into the internal memory and activated to read / write the data file on the high speed device. 4. If the selected file is a program file, the program file is loaded from the high speed device into internal memory and activated. 5. If any of the files transferred to the high speed device is updated or newly created by the above operation 3, the file is transferred to the low speed device (hereinafter referred to as "retransfer") to update the file on the low speed device. Or reflect the result of new creation. It is necessary to perform the above series of operations. In the conventional technique, these operations are individually performed by using commands of a computer operating system (hereinafter referred to as OS).

[0003]

However, this has the following drawbacks. A. If you don't know how to use OS commands, you cannot use attribute 1. B. Decide which file to select (operation 1 above)
In order to do this, it was necessary to display a list of file names with an OS command and visually search for the desired file name. C. In order to transfer a file to a high-speed device (operation 2), the name of the file to be transferred had to be typed in for each copy command of the OS. D. When the contents of file update or new creation are reflected in the low-speed device (operation 5), it is necessary for the operator to visually judge which file has been updated. E. Each time the characteristic 1 was used, the above operations 1 to 5 had to be repeated without omission. F. In particular, if the operation of the above 5 is forgotten, the updated content or the newly created content will be lost, so that the convenience of characteristic 1 cannot be used with confidence. G. Regarding the above 2 and 5, a method of simplifying the operations of B, C, and D by collectively transferring a plurality of files on the storage device by operating the command of the OS is conceivable. As a result, the transfer takes an extra transfer time, and the advantage of the characteristic 1 that the time required for reading and writing is shortened is diminished.

[0004]

In order to surely execute the above-mentioned series of operations 1 to 5 without omission, the procedure of the operation is a computer program (hereinafter referred to as program 1).
It was established as a method of using attribute 1 by fruiting on. Regarding the series of operations 1 to 5 above,
Since it is considered that the occurrence rate of file destruction will increase as the frequency of writing to the storage device increases, the program 1 has a file backup automatic creation function as a countermeasure. By incorporating this series of operations into a computer program and incorporating an automatic backup function, we were able to meet the demand for data protection when using Feature 1 and succeeded in ensuring stable operation of the system.

[0005]

The program 1 is placed in the storage device of the computer so that it can be activated, and then the program 1 is activated in response to an input request from the OS. Thereafter, the series of operations 1 to 5 described above is automatically executed and a file backup is automatically created by simply selecting the file name of the file to be transferred with the cursor in response to the input request from the program 1 side.

[0006]

EXAMPLE The algorithm of Program 1 described above is as follows. Get the date and time when the program starts from the internal timer of the computer. Obtain a list of file names on the low speed device from the low speed device. Ask the operator whether to select files individually. If the answer to the above question is YES, the file name list on the low-speed device is displayed on the screen, and the operator is allowed to select which file to select. The selection can be easily done by moving the cursor on the screen and pointing to the file name. If the STOP key is pressed in the above state, the execution of the program is stopped and the program 1 is terminated. If the SPACE key is pressed in the above state, the file selection is ended and the program 2 is executed. As soon as the file name is specified with the cursor without pressing the above, the specified file is transferred to the high-speed device, the transferred file name is displayed on the screen indicating that the file has been transferred, and then the file selection is returned to again. . If the answer is NO, the file name list on the low speed device is displayed on the screen and all the files listed in the low speed device file name list are transferred to the high speed device. In the above, each time a file is transferred, the fact that the file has been transferred is displayed on the screen. (10) If all files have been transferred in the above, or if the SPACE key is pressed in the above, program 2 is executed. (11) After the program 2 is executed, a file name list and a file creation date / time list on the high speed device are acquired from the high speed device. (12) For all files on the high-speed device, check whether the file creation date / time is newer than the program start date / time, and make a backup of the files with newer file creation date / time. (13) For all files on the high-speed device, check whether the file creation date / time is newer than the program start date / time, and retransfer the file with newer file creation date / time to the low-speed device. (14) Ask the operator if all files on the high speed device can be deleted. (15) If the answer to the question of (14) above is YES, all files on the high speed device are erased and the program 1 is terminated. (16) If the answer to the question of (14) is NO, the program 1 is terminated without erasing the file on the high speed device. As described above, if a computer program is created based on the algorithm of (16), no matter what computer language it is written in, the following (1) to (3)
The feature 1 can be used in the form of. (1) Use as independent software. (2) Incorporation into other software to use it to enhance the functionality of that software. Simple use of the algorithms (3) to (16) without the file backup function.

【The invention's effect】

A '. Many people who do not know how to use OS commands can now easily perform high-speed reading and writing of files using attribute 1. B '. In order to decide which file to select (operation 1), it suffices to point the target file name with the cursor from the file name list displayed by the program 1. C '. The process of transferring the file to the high-speed device (operation 2) is automatically executed by the program 1 in response to the instruction at B ', so that the trouble of typing in the file name becomes unnecessary. D '. When updating or newly creating a file is reflected in the low-speed device (operation 5 above), program 1 checks the file creation date / time to determine whether it needs to be retransferred to the low-speed device, and only the necessary files Since it is retransmitted, it is not necessary for the operator to visually judge. E '. Since each operation is executed by the program 1, the operation can be performed in a shorter time than a human operation, and the user does not need to be bothered by each operation. F '. Since the above-mentioned operations 1 to 5 are executed by the computer program, there is no fear that the operation will be leaked, and the risk that the updated content or the newly created content is lost due to the operation leakage is avoided. G '. Regarding the above 2 and 5 and automatic creation of backup, since the program 1 selects and executes only the file that has been updated or newly created, it is possible to take advantage of the characteristic 1 of shortening the time required for reading and writing. Became.
