As a conventional technique for designating a plurality of processing targets having a hierarchical structure composed of a plurality of files, for example, Japanese Patent Laid-Open No. 62-29
The thing described in 3359 gazette is known. In this method, the selected file information is temporarily stored in a memory, and file operations such as deletion and copying are performed on the selected file after the selection operation is completed.

[Problems to be solved by the invention]

The above-mentioned prior art does not take any measures when a specified file has another file that is subordinate to the specified file.

According to the present invention, when there is another file that is dependent on a specified file below the specified file, the specification of the other file is disabled, and a plurality of files to be subjected to file processing are specified. It is an object of the present invention to provide an information processing apparatus suitable for simplifying a user's operation at the time.

[Means for solving the problem]

An information processing apparatus according to the present invention for achieving the above object has a processing unit, a storage unit, a display unit, and an input unit, and has a hierarchical structure composed of a plurality of files stored in the storage unit. Displaying an object on the display means,
In the information processing apparatus configured to perform the file processing by the processing unit on the file specified by the input unit among the displayed processing units, the display unit may display a list of the processing targets of the hierarchical structure on the display unit. Displaying, for the displayed list of processing targets, a plurality of files is specified by the input means,
When the file specified by the input device has another file which is subordinate to the lower file, the specification of the other file by the input device is prohibited. [Operation] According to the configuration of the present invention, when the file specified by the input device has another file that is subordinate to the lower file, it is impossible to specify the other file by the input device. It is possible to prevent an extra designation operation such as duplicate designation of both upper and lower files in the same hierarchy.

〔Example〕

 Hereinafter, a detailed description will be given with reference to an embodiment of the present invention.

FIG. 2 shows an example of the configuration of the present invention, which comprises an input device 1 such as a keyboard, a display device 2, a CPU 3, a main memory 4 for storing processing programs and the like, and a file storage memory 5 such as a flexible disk. Is done.

The keyboard 1 has a delete key 11, as shown in FIG.
It comprises an end key 12, a designation key 13, a release key 14, an up cursor movement key 15, a down cursor movement key 16, and the like.

In the main memory 4, as shown in FIG. 5, the cursor position CRS @ POS, FILE @ TBL storing file information to be displayed on the screen, file information N @ FILES stored in FILE @ TBL, screen Number of file information displayed above NUM
{D, HEAD of the file information displayed on the screen}
D and last LAST @ D.

FILE ＄ TBL is the file and directory name N
AME, type KIND (1: file, 10: directory, OFFH:
Other), level LEVEL (0 at the top of the hierarchy, 1 at depth)
Each time it is incremented by +1), specified or not APNT (0: not specified (can be specified), 1: specified (can be released), 2: specified,
And cannot be released).

Hereinafter, the operation of the embodiment will be described with reference to the flowchart of FIG.

First, a subroutine DISPLAY @ FILES shown in FIG. 6 is called to display a file list (61).

The subroutine DISPLAY @ FILES calls the subroutine READ @ FILE @ INF shown in FIG. 7, accesses the file storage memory 5, and stores the file information in FILE @ TBL (i),
i = 0, 1,..., N ＄ FILES−1. Next, the subroutine DISPLAY shown in FIG. 8 is called, and the result is displayed.

For example, in the case of a file with the structure shown in Fig. 3, document 1.
DAT → Holder 01.DIR → Document 2, DAT → Holder 02.DIA →
Holder 03.DIR → Document 3.DAT → Document 4.DAT → Document 5.DAT →
The file information is acquired in the order of holder 04.DIR → dictionary.DIC, stored as shown in FIG. 5, and the files of all layers are displayed as shown in FIG.

After displaying the file list, accept the key input (6
2).

If the input key is the designated key 13 (63),
Calls APPOINT to perform target specification processing (64).

When the input key is the release key 14 (65), the subroutine
Call CANCEL to perform the specified release processing (66).

If the input key is the @ key 15 (67), the subroutine UP @ CURSOR shown in FIG. 12 is called to move the cursor one line upward in the screen. (68).

If the input key is the down key 16 (69), the subroutine DOWN @ CURSOR shown in FIG. 13 is called to move the cursor one line downward in the screen (70). The target of designation and cancellation is
The cursor is positioned.

If the input key is the delete key 11 (71), delete processing is performed on the specified target (72).

If the input key is the end key 12 (73), the process ends.

As shown in FIG. 10, the subroutine APPOINT for performing the target designation processing first checks whether the file or directory at the position indicated by the cursor can be designated (641). If it cannot be specified, the process ends.

If the command can be issued, the file or directory is set (642), and the line in which the file or directory is displayed is displayed in black and white inverted (643).

Next, it is checked whether the type is a directory (644). If it is not a directory, exit. In the case of a directory, all of the subordinate directories are designated and unremovable, and they are displayed in half-brightness in order to clearly indicate the designation and refusal (645).

As shown in FIG. 11, the subroutine CANCEL for canceling the specification firstly stores the file at the position indicated by the cursor,
Alternatively, it is checked whether the directory can be released (661). If it cannot be canceled, the process ends.

If cancellation is possible, the designation of the file or directory is canceled (662), and the black-and-white inverted display thereof is returned to the normal display (663).

Next, it is checked whether the type is a directory (664). If it is not a directory, exit. In the case of the directory, all the subordinate directories are set to a state in which designation or non-cancellation is impossible, and the half-brightness display is returned to the normal display (665).

FIG. 14 shows a flowchart of a subroutine DELETE for deleting a specified file and directory.

In this subroutine, the specified file and directory are deleted. In the case of a directory, files and directories under the directory are also collectively deleted.

For example, in FIG. 9, when the holder 02 and the DIR 21 are designated, the black and white display is reversed as shown in FIG. 15 (a). The lower files and the directory 22 are displayed in half-brightness and cannot be specified. Further, when the dictionary .DIC23 is designated, the result is as shown in FIG. 15 (b). If a delete key is input in this state, the files and directories 51 and the dictionary .DIC 52 below the holder 02 and DIR in FIG. 3 are deleted.

Further, the present invention can be performed by combining the function of displaying only each layer with the designation and deletion of an object.

According to this embodiment, the operation target can be designated across the layers. In addition, since a lower order object cannot be specified by the target specification, there is no extra specification.

Hereinafter, another embodiment of the present invention will be described with reference to the flowchart of FIG.

First, the subroutine DISPLAY @ FILES shown in FIG. 6 is called, and the file information is stored in FILE @ TBL (i), i = 0, 1,.
N ＄ FILES-1 and display the contents on the screen (8
1).

 Next, a key input is received (82).

If the input key is the designation key 13 (83),
Calls APPOINT2 and performs target specification processing (84).

When the input key is the release key 14 (85), the subroutine
Call CANCEL2 to perform the specified cancellation processing (86).

If the input key is the @ key 15 (87), the subroutine UP @ CURSOR shown in FIG. 12 is called to move the cursor one line upward in the screen (88).

If the input key is the down key 16 (89), the subroutine DOWN @ CURSOR shown in FIG. 13 is called, and the cursor is moved one line downward in the screen (90).

The target of specification and cancellation is the one where the cursor is positioned.

If the input key is the delete key 11 (91), the subroutine
Call DISP @ OBJ and perform processing to leave the specified target that is the minimum required to execute the processing from the specified target (9
2), a subroutine DELETE shown in FIG. 14 is called, and a deletion process is performed on the specified object (93).

If the input key is the end key 12 (94), the process ends.

As shown in FIG. 17, the subroutine APPOINT2 for performing the target specifying process firstly executes the file at the position indicated by the cursor,
Alternatively, it is checked whether a directory can be specified (841). If it cannot be specified, the process ends.

If the file or directory can be specified, the specified file or directory is set (842), and the line in which it is displayed is displayed in black and white inverted (843).

The subroutine CANCEL2 for canceling the specification
As shown in the figure, first, it is checked whether the file or directory at the position indicated by the cursor can be released (861). If it cannot be canceled, the process ends.

If cancellation is possible, the specification of the file or directory is canceled (862), and the black-and-white inverted display of the file or directory is displayed based on the normal display (863).

A subroutine DISP @ OBJ that performs processing to leave the specified target necessary for executing the processing from the specified target.
Checks whether a file or directory is specified as shown in Fig. 19 (921), and if specified, cancels the specification of the lower order and normally displays black and white inverted display Return (922). Do this for every file or directory.

For example, in FIG. 9, when the holder 02.DIR21 is designated, the black and white display is reversed as shown in FIG. 20 (a). Further, when the document 4.DAT24 and the dictionary .DIC25 are specified, the result is as shown in FIG. 20 (b). When the delete key is pressed in this state, the screen shown in FIG.
Files and directories under the folder 02.DIR in the figure 51
And the dictionary .DIC52 are deleted.

In the present invention, the function of displaying only each layer and the designation and cancellation of an object can be performed in combination.

According to this embodiment, the operation target can be designated across the layers. In addition, since the target to be actually processed is specified, the target processing can be easily understood.

[Effects of the Invention] According to the present invention, it is possible to easily designate a plurality of targets across a hierarchy.
