In this discarding operation, as shown by 601, the binder 17 is opened, the contents are displayed, the cursor 24 is moved to the icon 604 of the data to be discarded, and the button of the pointing device (PD) 5 is pressed. After moving (dragging) the cursor 24 to the trash box window 602 as it is, the button of the PD 5 is released to complete the process. By this operation, the data icon 604 existing in the binder 17 is moved to the trash can window 602. After that, when the desktop is terminated, all the entries in the trash box 16 and all the files indicated by the file names of the files in each entry are deleted. Thus, the binder or data moved to the trash can window 602 can be erased from the cabinet 15. In addition, as shown in FIG.
The name of the data file (including the binder file) corresponding to the icon moved to the trash 16 and the storage address of the file in the HDD 9 or FDD 10 are stored in the RAM 8.

FIG. 7 is a flowchart showing a processing procedure for instructing the above-mentioned data discarding, and a control program for controlling this processing procedure is stored in the ROM 7 described above.

In step S1, the icon pointed by the cursor 24 when the button of the pointing device 5 is pressed is checked, and as shown in FIG.
4 indicates the data file icon 604, the data management information of the binder 17 in which the data file exists is read from the HDD 9. Next, the cursor 24 is moved on the screen by a drag operation, and step S2
Check whether the position of the cursor 24 when the button of the pointing device 5 is released is above the trash can window 602. If it is not the trash box window 602, the process ends only by moving the icon designated to that position.

On the other hand, when the button is released in the trash can window 602, the process proceeds to step S3, and it is checked whether or not the instructed data file is opened elsewhere. If it is opened, the process proceeds to step S6 and is discarded. A message indicating that it is impossible to perform is displayed, and the process ends.

If the data file is not opened elsewhere in step S3, the process proceeds to step S4, and the process for moving the designated data file into the window of the trash box 16 is performed. Next, in step S5,
It is determined whether the data file can be moved normally, and if it can be moved normally, the process ends, but if the data file cannot be moved normally in step S5, the process proceeds to step S6. , As described above, the data is displayed as being non-discardable and the process ends.

The file corresponding to the icon moved to the trash box 16 in this way is subjected to a discarding process at the end of the desktop as shown in FIG.

FIG. 8 is a flow chart showing the operation of discarding the file corresponding to the icon moved to the trash box 16 when the desktop is closed.

First, in step S11, it is checked whether or not there is an icon that has been moved to the trash box 16 by the procedure shown in the flowchart of FIG. 7. If an icon exists in the trash box 16, the file corresponding to the icon is deleted. The data management information is read from the HDD 9, and in step S12, the corresponding entry and the file indicated by the file name in the entry are deleted from the HDD 9. Next, in step S13, it is checked whether or not these discarding processes have been performed on the data management information of the files corresponding to all the icons moved to the trash box 16, and if not, the process returns to step S12 to perform the above-mentioned process. I do. Thus trash can 1
The files corresponding to all the icons moved to 6 can be discarded.

In the above-described embodiment, when the data file corresponding to the icon moved to the trash box 16 is the end of the desktop, the entry corresponding to the file and the file indicated by the file name in the entry are stored in the HDD 9
Although it has been described that the corresponding file is discarded by deleting the file, the total size of the data or the binder corresponding to the icon moved to the trash box 16 exceeds the preset size. All of them may be erased when the Another embodiment that performs such an operation will be described.

FIG. 9 is a flow chart showing the discarding process of another embodiment of the present invention. The control program for executing this process is stored in the ROM 7.

Steps S21 to S26 are the same as steps S1 to S6 of the flow chart of FIG. 7, and the icon pointed by the cursor 24 when the button of the pointing device 5 is pressed is checked. As shown in the figure, when the cursor 24 points to the data file icon 604, the data management information of the binder 17 in which the data file exists is read from the HDD 9 or FDD 10. Next, the cursor 24 is moved on the screen by the drag operation, and it is checked whether or not the position of the cursor 24 when the button of the pointing device 5 is released in step S22 is on the trash can window 602. If it is not the trash box window 602, the process ends only by moving the icon designated to that position.

On the other hand, when the button is released in the trash box window 602, the process proceeds to step S23, and it is checked whether or not the instructed data file is open elsewhere.
If it is open, go to step S26,
A message indicating that it is impossible to discard is displayed and the processing ends.

If the data file is not opened elsewhere in step S23, the process proceeds to step S24, and the designated data file is moved into the window of the trash box 16. Next, in step S25, it is determined whether the data file can be moved normally. If the data file can be moved normally, the process proceeds to step S27, but if the data file cannot be moved normally, step The process proceeds to S26 and, as described above, the fact that the data cannot be discarded is displayed and the process ends.

In step S27, as shown in FIG. 10, the input window 110 is displayed, the default value of the disposal management size is displayed in the frame 111, and the value obtained by summing the sizes of the entries in the trash box 16 is displayed in the frame 112. .. This Figure 1
0, as shown in FIG. 6, the data icon 60
4 shows a state in which the window 110 is displayed when 4 is instructed to move into the trash box 16.

Next, in step S28, when the input of the discard management size is accepted and it is instructed by the keyboard 4 whether the value is input or the default value is acceptable, the display of the frame 111 is confirmed. Then, in step S29, the designated disposal management size is compared with the sum of the sizes of the entries in the trash box 16 to determine whether the total value is equal to or larger than the designated disposal management size. .. If the total value is equal to or smaller than the designated discard management size, the process returns to step S22 and the above-described processing is executed.

On the other hand, if the total value is equal to or larger than the designated disposal management size in step S29, the process proceeds to step S30, and all the data or binder entries corresponding to the icon in the trash box 16 are deleted from the data management information. , The corresponding file to HDD9 or FD
Erase from D10.

As another application example, (1) it is possible to set discard prohibition information for each data file as the data management information of the trash box 16, and at the end of the desktop, for example, the icon of the data file is the trash box. Even if the data file has been moved to 16, the information about the data file may not be discarded. As a result, data can be retained in the trash box 16 and the data in the trash box 16 can be used even when the desktop is restarted. (2) In addition to terminating the desktop, when the user accesses another room or another office, the file corresponding to the icon moved to the trash box 16 may be discarded. .. Thereby, the discarding operation can be performed more frequently. (3) As the data management information of the trash box 16, each data file is given a priority order, and when the total size of all entries exceeds the disposal management size, as in the other embodiment described above, the priority order thereof. The entries may be deleted in ascending order, and the discarding operation may be terminated when the total size of all entries becomes equal to or smaller than the discard management size. As a result, even if the disposal management size is exceeded, all the files corresponding to the icons moved to the trash box 16 are not erased, and more detailed disposal processing can be performed.

Further, instead of this priority order, for example, date information may be referred to and the oldest date may be deleted.

Alternatively, the data may be discarded in descending order of data size instead of priority.

The present invention may be applied to a system composed of a plurality of devices or an apparatus composed of a single device. It goes without saying that the present invention can also be applied to the case where it is achieved by supplying a program for implementing the present invention to a system or an apparatus.

As described above, according to this embodiment, the file instructed to be discarded is discarded, for example, as the process at the end of the program without performing the restart process of the computer system, so that the data is discarded. It becomes possible to effectively use the storage area of.

According to another embodiment, when the data size of the file instructed to be discarded exceeds the preset data size, the file is erased, so that the area for saving the data is free. Area can be secured and used effectively.
