Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a file saving method of an information processing apparatus for creating data such as a document by a simple method or a simple structure and saving it as a file in an auxiliary storage medium.

[0002]

2. Description of the Related Art A floppy disk is a convenient medium for storing data such as a document created by using a word processor and a document created by data processing using a personal computer.

Generally, the stored data is called a file, the storage unit of the auxiliary storage device is roughly divided into two, and a data file storage unit for storing the data itself and each file stored in the data file storage unit are managed. The file management storage unit identifies and stores a plurality of files by file names.

Therefore, in the case of so-called overwriting saving in which the file name is the same as the already saved file name, there is a case where it is desired to recover the file before overwriting. In order to recover the file before overwriting after such overwriting, the data content recovery method described in Japanese Patent Laid-Open No. 1-240943 attempts to output to the medium when overwriting on the medium. After reading the data from the area corresponding to the position and size and storing it in the recovery file that has been secured in advance, overwrite it on the medium, and after this overwrite, from the recovery file based on the instruction of the incorrect operation Data is written in the original area of the medium to be restored. A data content recovery method that can recover the file before overwriting after accidentally overwriting is convenient.

[0005]

However, in the above-mentioned conventional technique, the saved file is read every time the file is saved by overwriting with the same file name as the saved file name.
There is a problem that overhead is required when a medium such as a floppy disk is used because it is necessary to write the recovery file. In addition, a dedicated process for recovery from the recovery file is required.

An object of the present invention is to provide a file saving method for protecting a file before overwriting by a simple method when the file is overwritten by mistake.

[0007]

In order to achieve the above object, the present invention provides a document data creating step of creating target document data while displaying character information input by an input device on a display device, A file saving method for an information processing apparatus, including a saving step of identifying the document data by a file name, saving a plurality of files in an auxiliary storage device, and an updating step of using the saved plurality of files as input data for editing. In the saving step, when a file having the same file name as the file name for saving the document data exists in the auxiliary storage device,
Saving the file of the information processing apparatus, including the steps of changing the file name of the saved file to a specific file name and deleting the file with the specific file name before saving the document data. Provide a way.

[0008]

According to the present invention, when a plurality of files stored in the data file storage section are identified and managed by file names according to the stored contents of the file management storage section, data such as created documents are stored in the auxiliary storage medium. If there is a saved file with the same file name when you save it, after changing the file name of the saved file to a specific file name such as "temporarily saved document", the data such as the created document was specified. By storing and saving with a file name, the saved file that was overwritten and saved is protected. Also, when changing the file name of the saved file,
If there is a saved file with the same file name as the file you are trying to change, delete the saved file and then change the file name so that only the saved file that was last overwritten and saved. Protect.
As a result, even if the file is overwritten with the same file name as the saved file, the saved file is saved with the changed file name. If you notice from
If the renamed file can be specified as the file to be read and updated, the saved file can be recovered.

A method of storing a file of data such as a document by the information processing apparatus configured as described above will be described with reference to FIGS.
This will be described with reference to FIG.

FIG. 2 shows a data processing flowchart for input data storage performed by the overall control device 3 of FIG.

The input data to be saved is stored in the input data storage area 401 of the temporary storage device 4.

When the saving of the input data is started, first, the file name of the input data to be saved is input (step 101). This process is performed by the file name input control unit 30.
2 to input the file name from the input device 1, FIG.
A file name input screen 601 as shown in FIG. 3 is displayed on the display device 2, and the input device 1 performs a file name input process, and the input file name is stored in the file name storage area 402 of the temporary storage device 4.

When the input of the file name is completed, the file name determination unit 305 stores the file name stored in the file name storage area 402 of the temporary storage device 4 and the auxiliary storage device 5.
The file names stored in the file management storage unit 501 are compared to determine whether or not files with the same file name have been saved (step 102). If the same file name does not exist, the process proceeds to step 108. If the same file name exists, a warning message that a data file with the same file name has been saved is displayed (step 103). In this step 103, in order to input the coping process from the input device 1, the coping process selection screen 603 as shown in FIG. 4 is displayed on the display device 2. The handling number input control unit 306 inputs the handling number from the input device 1, and the inputted handling number is stored in the handling number storage area 403 of the temporary storage device 4.

When the input of the handling number is completed, the handling number stored in the handling number storage area 403 of the temporary storage device 4 is determined, and the process corresponding to the handling number is moved (step 1
04). When "cancel processing" of the handling 0 is instructed, the document saving processing is ended. When “Retry again ...” of Action 1 is instructed, the process is performed again from step 102. When “Re-enter file name” of instruction 2 is instructed, the process is restarted from the file name input in step 101. If “Change the file with the same file name that has been saved to“ Temporarily saved document ”(Delete the temporarily saved document that is being saved) and save” in Action 3 is indicated, the file name determination unit 305 Compares the file name stored in the file management storage unit 501 of the auxiliary storage device 5 with the "temporary storage document", and determines whether the "temporary storage document" exists (step 10).
5). If no “temporarily stored document” exists, the process proceeds to step 107. If a "temporarily stored document" exists,
The "temporarily stored document" is deleted (step 106).

Next, in order to protect the saved file having the same file name, the file name change processing unit 307 changes the file name stored in the file management storage unit 501 of the auxiliary storage device 5 to "temporary storage document". The name is changed to (step 107).

Next, the input data stored in the input data storage area 401 of the temporary storage device 4 is stored in the data file storage unit 502 of the auxiliary storage device 5, and the data file stored in the data file storage unit 502 is stored. The management information and the file management information such as the file name are stored and saved in the file management storage unit 501 (step 10).
8).

As described above, before overwriting and saving a data file with the same file name, the saved file name is changed to perform virtual overwriting, and the saved data file can be protected from data destruction due to an erroneous operation. To do so.

Further, the file management storage unit 501 is made to be able to manage the protection attribute of the file, and the protection attribute is set to the file of "temporary storage document" which is a specific file name used for protecting from data destruction due to erroneous operation. "," And then "temporarily saved document" with the file name specified by the user
May not be directly stored in the.

In order to update the document file saved as described above, the update document designation screen 605 shown in FIG. 5 is displayed, and a temporarily stored document can be designated and updated in the same manner as a normally saved document. , Does not need special processing for backup file recovery.

[0027]

According to the present invention, only one file before overwriting is saved in the same storage medium or the same storage area by changing only the file name of the file management storage unit that manages data files. Therefore, the space occupied by the auxiliary storage medium such as a floppy disk is small, and optimum file protection is possible. Further, since only the file name of the file management storage unit that manages the data file is changed, the overhead for storing the backup file can be avoided.

Further, if the user realizes that he / she has overwritten by mistake and wants to recover the saved data file, he / she does not need any processing for recovering the backup file and renames the renamed data file to another file. It can be updated as easily as a file.
