Abstract

PURPOSE:To improve the operation efficiency and to eliminate a wrong editing position, etc., by displaying the hierarchical relation between files and directories on a screen and editing directories. CONSTITUTION:The screen of a display is divided into a nest information map display part A and a directory information input part B, a nest information map, i.e. the hierarchical relation between directories below the root directory and files is displayed at the nest information map display part A. The file structure is therefore clear at a glance, it is easily judged that a directory D4 to be generated is positioned under a directory D3, and a command is inputted at the directory information input part B on the display screen to easily and speedily generate the directory D4. Consequently, directories can be edited with efficiency and a mistake is hardly made.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for editing a directory of files having a hierarchical structure.

[Conventional technology]

According to the conventional directory editing method of this type, when a one-character command is input, only the directory name and file name one level below the level currently being pointed to are displayed on the display screen. Therefore, when creating, deleting, moving, etc. a directory in a certain hierarchy, it is necessary to trace the directory to the illustrated hierarchy by repeatedly inputting commands while checking the status of the directory for each hierarchy on the screen.

For example, suppose that a directory D4 is created under a directory D3 as shown in (b) regarding a hierarchically structured file as shown in (,) in FIG. The display screen for this work is as shown in (Q).

That is, by inputting the command ``■'', the position is placed on the display D1, by inputting the command ``■'', the state under the directory D1 is instructed to be displayed, and in ``■,'' the directory D2. It is displayed that there is D3. By inputting the commands ■ and ■,
It instructs to display the status under the directory D2, and it is displayed that files Fl and F2 are located in ■. Next ■ and ■
In response to the command input, it is displayed in ■ that there is a file F3 under the directory D3, and by the next [phase] and command input in ■, directory D4 is created under the directory D3, and the result is displayed in ■. be done.

[Problem to be solved by the invention]

However, according to the above-mentioned conventional method, when the hierarchical structure of files becomes complicated, it takes time to check it, the efficiency of directory editing is low, and errors in editing positions are likely to occur.

The object of the present invention is to provide a directory editing method for a single-layered file that allows efficient directory editing even when the file has a complex hierarchical structure and is less prone to errors. .

[Means to solve the problem]

In order to graphically achieve the above object, the present invention displays a nest information diagram that graphically represents the hierarchical relationship between files and directories of a hierarchically structured file on a display screen, and interactively displays the nest information diagram while referring to the nest information diagram. Create a directory (
addition), deletion, movement, etc.

More specifically, the display screen is divided into a nest information diagram display section 6 and a directory information input section, and the nest information diagram display section displays the nest information diagram, that is, the hierarchical relationship of directories and files that are connected from the top root directory. do. If this nest information diagram cannot be displayed at once, a part of it is displayed, and the part of the directory immediately above the directory to be edited is displayed on the screen by screen scrolling, and it is indicated (pointed to). As a result, the link status (environment setting information) from the root directory to the designated directory is displayed, and command information is also set for the system.

[For production]

When creating a directory as shown in (b) for the hierarchical structure file shown in (,) in Figure 2, for example, as shown in (d) in Figure 2, the nest information diagram display area A of the display screen is Since the nest information diagram shown in the figure is displayed, the file structure can be clearly seen by the operator, and it can be easily determined that the directory D4 to be created should be placed under the directory D3. Therefore, by inputting commands as shown in the directory information input section B on the display screen, the directory D4 can be created easily and quickly, and mistakes are less likely to occur.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing a schematic configuration of a system according to an embodiment of the present invention. This system includes an input device 11 consisting of a keyboard, etc., a central processing unit @ (CPU) 1
2. It consists of a character display device 17, a file device (external storage device) 18 in which files with a hierarchical structure are stored, etc. - The central processing unit 12 has a command analysis process that analyzes commands input from the input device 11. A mechanism 13 (actually a program running on the central processing unit 12), a mechanism 14 (actually a program) for editing and controlling information on commands and hierarchical files, and a storage area 15 necessary for this processing. It consists of a control processing mechanism 16 (also actually a program) for controlling the screen display of the character display device 17, and the like.

The storage area 15 includes a buffer 15a for directory information of hierarchically structured files, a logical screen buffer 15b that holds the entire nest information diagram created based on this directory information, and a physical screen buffer 15b that holds display data on the screen of the character display device 17. There is a screen buffer 15c.

In the case of a file with a complex hierarchical structure, the nest information diagram is generally quite large and cannot be displayed in its entirety on the character display group [17 screens] at once, so one of the nest information diagrams on the logical screen buffer 15b is The image is displayed on the screen by cutting out the portion and copying it to the physical screen buffer 15C. Note that the portion to be cut out and displayed can be specified using the input device 11.

As an example, assume a file with the structure shown in FIG.

Dn is a directory, and Dl therein is the root directory. Fn is a file.

In the case of this hierarchical structure file, the logical screen buffer 15a
In this case, a nest information diagram as shown in FIG. 4 is created by the editing control processing mechanism 14. The data format of this nest information diagram is such that the directory name and file name are in character format, and the symbols representing the link (nest) status are also commonly used special characters. Further, the root directory is positioned at the upper left corner of the logical screen buffer 15b, and lower directories are arranged to the right. A part of such a nest information diagram is copied to the physical screen buffer 15c and displayed on the screen as shown in FIG. It can be scrolled. Therefore, the hierarchical relationship of directories and files can be easily confirmed on the screen simply by scrolling the screen.

FIG. 5 shows an overview of the directory editing function.

(a) is a directory D under the existing directory D3.
4 shows the directory structure before and after the editing process to create (add) 4. (b) shows the directory structure before and after the editing process of deleting the directory D4 under the directory D3. Further, (c) shows the directory structure before and after the editing process in which the directory D4 under the directory D2 is moved under the directory D3.

FIG. 6 is a flowchart of directory editing processing. The interactive directory editing processing operation with reference to the nest information diagram will be explained along this flowchart.

When a startup command for directory editing of a specific file is input from the input device 11, the command analysis processing mechanism 1
3, the editing control processing unit 14 reads the directory information of the file specified by the file device 18 into the directory information buffer 15a, and based on this directory information, logically creates a nest information diagram expressing the hierarchical structure of the file. It is developed (created) in the screen buffer 15b (process 101), and then a part of the logical screen buffer 15 is copied to the physical screen buffer 15c.
The range to be copied can be scrolled vertically and horizontally using the keyboard 11. The contents of this physical screen buffer 15c are as follows.

Displayed on the screen of the character display device 17 under the control of the screen display control processor #116 (processing 102),
The system waits for input of an editing command.

Note that the screen of the character display device 17 is
As shown in (d) of the figure, it is divided into a nest information diagram display part and a directory information input part, and the contents of the physical screen buffer 15b are displayed only in the nest information diagram display part.

The operator displays the necessary part of the nest information diagram on the screen by scrolling, confirms the location of the directory to be edited, and inputs one editing instruction command.

This command is analyzed by the command analysis processing mechanism 13 and sequentially displayed on the directory information input section of the screen of the character display device 17 (processes 101 to 105).

In the case of "build 8 re-create", by pointing to the directory directly above the directory to be created by the operator and inputting the name of the directory to be created, the directory will be created and the information will be added to the directory. The contents of the logical screen buffer 15b are updated based on the updated directory information (process 107 and process 1).
10), proceed to process 102, and therefore the edited nest information diagram is displayed.

In the case of "Delete Directory", by inputting the directory specified by the operator to be deleted, the existence of files and directories under that directory is checked, and if there are no files or directories, deletion is possible. Directory is directory information input buffer 15
a, and the contents of the logical screen buffer 15b are updated according to the directory information after deletion (processing 11).
1 to process 115) and returns to process 102. however.

If there is a valid directory or file under the designated directory and it cannot be deleted, the process returns from process 113 to process 102 without performing the deletion process.

In the case of "directory movement", the operator specifies the source directory and destination directory, and the process of chaining the source directory to the destination directory is performed by the directory information input buffer 15a.
The content of the logical screen buffer 15b is updated (from process 116 to process 118).

When the input command is an instruction to "end", the editing control processing mechanism 14 inputs the directory information of the corresponding file in the file installation [18] based on the contents of the directory information input buffer 15a (directory information after editing). Rewrite (process 119), which means that the directory has actually been edited.

Note that if the nesting structure is deep, it will be difficult to display the entire nesting information diagram on the screen, but by scrolling the screen you can easily check the directory hierarchy structure of the necessary part.

There is no particular inconvenience, especially in each edit, the link status from the root directory to the specified directory (
Displaying the environment settings information on the screen also makes it easier to check the overall structure.

〔Effect of the invention〕

As described in detail above, according to the present invention, it is possible to edit a directory by making the directories of hierarchically structured files and the hierarchical relationships of files clear on the screen, thereby improving the work efficiency and editing the directories. Mistakes in editing positions can be prevented.
