Abstract

PURPOSE:To make users recognize the importance of deletion of a file by displaying a process where the file is deleted to a CRT by means of an analogy showing a fact that the file is burnt out. CONSTITUTION:When a user pushes a deletion key 6 for indication of a file deleting process, a file deletion control part 9 starts a deletion cursor generating part 10. The part 10 produces a deletion cursor 18 having a flame pattern. Then the user operates a cursor key 5 to shift the cursor 18 to the position of a desired file name. Then a random dot pattern generating part 12 is started for generation of the dot address of an indicated file name display area 17 at random. This random address is written over the correponding file name display area of a screen memory 13. Thus a file is erased.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a file deletion control method in a computer system, and in particular to a method for preventing important data files from being lost due to careless instructions for file deletion processing by a user. The present invention relates to a file deletion control method that displays a warning to recognize the seriousness of a file in parallel with delaying the execution of a deletion process.

[Conventional technology]

In general, in computer systems, the simpler the operational functions for processes such as file creation, updating, and deletion, the easier and more efficient they are to execute.

However, once the file deletion process is executed, the data is lost forever, so it is better not to process it as efficiently as it will give the user a chance to withdraw the instruction or restore the file, which will actually meet the needs of the user. In some cases, they are responding.

For example, in computer-based interactive learning systems, the learning record file is carefully managed as a valuable collection of past learning progress records of individual learners, but such systems do not have a file deletion function. It is normal for users to be especially careful when using it. Conventionally, in order to reduce such mental burden on users, when a user instructs to delete a file, a procedure has been implemented in which the user reconfirms whether the instruction is legitimate. There were many systems that installed the file and then deleted it. To give one example, when a user instructs to delete a file, the system displays "Are" on the display.
There is a system that outputs a reconfirmation message "you 5ure (YorN)" and allows the user to select a response of "Y (Yes)" or "N (No)".

[Problem that the invention seeks to solve]

In the conventional technology, even if a response procedure is provided to request reconsideration in response to a file deletion instruction from a user, if the user lacks awareness of the importance of file deletion,
Since the system automatically responds to the effect that the instruction is valid and immediately executes the deletion process, there is a problem in that reliability is still lacking from the perspective of users' general behavioral psychology.

[Means for solving problems]

In order to solve the above-mentioned conventional problems, the present invention provides a means to intuitively make the user aware of the seriousness of the situation of file deletion. Using the analogy of a fire burning out, the display is used to help the user understand. The specific means for this includes, in a computer system, a means for displaying a file list on a display screen, a means for inputting a file deletion instruction, a means for inputting a cancellation of a file deletion instruction, and a means for responding to the operation of the above-mentioned file deletion instruction inputting means. means for displaying a deletion cursor in a flame-like pattern; positioning means for making the deletion cursor correspond to a deletion target file name in the displayed file list; and a deletion target file to which the deletion cursor is associated as the deletion target file. means for image-processing the name so as to burn it out within a certain period of time, and means for canceling the file deletion instruction and restoring the display screen when the file deletion instruction cancellation input means is operated by a predetermined time within the certain period of time; , means for executing deletion processing of the file corresponding to the file name to be deleted if the file deletion instruction cancellation input means is not operated by the predetermined time, and if there is a file deletion instruction, prior to execution. This system is characterized by displaying a warning for a certain period of time and making it possible to cancel the file deletion instruction.

〔Example〕

The details of the present invention will be explained below based on examples.

FIG. 1 is a configuration diagram of a system according to an embodiment of the present invention,
FIG. 2 is a control flow diagram thereof. In Figure 1, 1
is the keyboard, 2 is the computer body, 3 is the color CR
T is a display device, 4 is a file memory such as a floppy disk, 5 is a cursor key, 6 is a delete key, 7 is a carriage return key, 8 is another key, 9 is a file deletion control section, 10 is a deletion cursor generation section, 11 12 is a random dot pattern generator; 13 is a cursor position control unit;
is screen memory, 14 is pattern dot number counter, 15
16 is a display number, 17 is a file name display area, 18 is a deletion cursor, and 19 is a random dot pattern generation section. Next, we will discuss the operational functions of each element.

When the user issues a file deletion instruction using the deletion key 6, the file deletion control unit 9 displays a deletion cursor with a special flame pattern according to the present invention as a preliminary step, and displays a flame on the file name to be deleted. The file processing unit 1 controls the display of the file name as it burns and progresses in red, and only if the deletion instruction is not canceled within a certain period of time.
5 and controls the file deletion process to be executed.

In response to the operation of the delete key 6, the delete cursor generator 10 generates a cursor pattern 20. in FIG. 3 which is different from the normal cursor pattern.
Two large and small flame patterns as shown at 21 are alternately generated, and a deletion cursor 18 dynamically representing a red flickering flame is displayed on the screen of the display device 3.

The cursor position control unit 11 positions the deletion pattern 18 to the deletion target file name according to the instruction of the cursor key 5. The determined position is notified using the carriage return key 7.

The random dot pattern generation unit 12 displays a red color that fills up the file name display area 17 of the file to be deleted over time, where the deletion cursor 18 is located, in order to represent the progression of the file name of the file that has been instructed to be deleted. A random dot pattern 19 is generated. FIG. 4 shows an example of the display state at the time elapsed to, tl, and t2.

The screen memory 13 stores display data including a deletion cursor 18, a random dot pattern 19, etc.
Further, it is read out to the display device 3.

The pattern dot number counter 14 counts the number of dots in the random dot pattern 19 generated by the random dot pattern generation section 12, and when it reaches a predetermined constant amount (for example, an amount corresponding to approximately one minute), The execution of the file deletion process is notified to the file processing unit 15.

If any of the other keys 8 is operated before the pattern dot number counter 14 reaches a predetermined amount, the file deletion control unit 9 recognizes that the file deletion instruction has been canceled, and the display device The deletion cursor 18 and random dot pattern 19 displayed on the screen are erased, and the control state is cleared.

Here, on the screen of the display device 3, the file processing unit 15 displays a list of files stored in the file memory 4 as shown in the figure, and the user deletes the file with display number 2 from this list. Make it what you want.

The subsequent operations will be explained according to steps (1) to (2) shown in the control flow of FIG.

■First, the user presses the delete key 6 to instruct deletion processing. When the file deletion control unit 9 detects that the deletion key 6 has been pressed, it activates the deletion cursor generation unit 10.

(2) The deletion cursor generating section 10 generates a deletion cursor 18 having a flame pattern.

Next, the user operates the cursor key 5 to move the deletion cursor 18 to the desired file name position (number 2). In this case, the deletion cursor 18 is displayed at an intermediate position between the display number 16 and the file name display area 17.

■By pressing the carriage return key 7 when the deletion cursor reaches the position of the desired file name, the file deletion control unit 9 selects the file to be deleted from the current deletion cursor 1.
8 is located in the file name.

Then, the random dot pattern generating section 12 is activated.

(2) The random dot pattern generation section 12 randomly generates a dot address for the specified file name display area 17 and overwrites it in the file name display area of the screen memory 13. As a result, as shown in Figure 4, the file name (DBMO) changes over time to a random dot pattern 19.
The area is gradually filled in, and eventually becomes invisible. Note that the number of dots in the random dot pattern generated at this time is counted by a pattern dot number counter 14.

(2) During this time, it is also monitored whether any other keys 8 are pressed.

When any other key 8 is pressed in ■■, the deletion instruction is invalidated, the deletion cursor 18 and the random dot pattern display are cleared, and control is returned to the beginning.

While the other keys 8 are not pressed in ``■■'', the pattern dot number counter 14 monitors whether the number of dots in the random dot pattern reaches a predetermined amount.

When the number of dots in the random dot pattern reaches a predetermined amount in ■■, the file processing section 15 deletes the corresponding file in the file memory 4.

In this way, when a user instructs to delete a file, an image of the file burning out is always displayed after a certain amount of time, and the user is informed that the file deletion is abnormal. make you realize that.

Note that the key means used in this embodiment for instructing deletion, canceling, etc. is only one example, and can be easily modified to any other input means, and the pattern of the deletion cursor may also be the same as shown in the figure. Similarly, instead of the random dot pattern, any suitable image pattern representing the progress of the file may be used.

Further, as means for delaying execution of the file deletion process, a clock counter or other timer may be used instead of the pattern dot number counter.

〔Effect of the invention〕

As described above, according to the present invention, even a user who is not familiar with computer systems can intuitively recognize the importance of file deletion processing, and is therefore expected to reconfirm with careful consideration. It is possible to perform file deletion processing with high reliability.
