DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folder sharing apparatus and a folder sharing method used for managing a plurality of pieces of information in a folder format.

[0002]

2. Description of the Related Art Conventionally, a plurality of pieces of information have been stored in a database in a folder format, and each piece of information has been systematically managed. At this time, when folders are created in the database, a folder tree structure diagram (folder hierarchy structure diagram) representing the inclusion relationship between folders is created. For example,
There is information about two products P _1, P _2, and the folder tree view for each product P _1, P ₂ is a structure as shown in FIG. Then, the folder f ₁ the following folders or files of the folder tree view of the product P ₁ is assumed to be identical to the folder f ₂ following folders or files in a folder tree view of the product P _2. In this case, it is possible to create a folder tree structure diagram of a product P _2, copying a folder f ₁ the following folder or file. To perform such copying, the operator uses the mouse on the display screen, as well as specify the folder f _1, specifies the location of a folder tree view of the product P ₂ which is the copy destination. Thus, all of the specified folder f ₁ the following folder or file is created in the folder f ₂ following folders or database as a file is copied to the specified location. However,
It is not possible to copy only some intermediate folders in the folder tree structure diagram. The copy source folder f
₁ or less folder or file and copy destination folder f ₂
The following folders or files are managed independently.

[0003]

[SUMMARY OF THE INVENTION However, when performing such copying, because all folders f ₁ the following folder or file specified at the time of the copy is made in the folder f ₂ following folders or database as a file, The data capacity increases. Moreover, since it is managed independently of the copy source folder f ₁ the following folder or file and the copy destination folder f ₂ following folders or files, for example, when correcting the folder name of the folder f _1, folder f ₁ and must be corrected for the folder f _2, respectively, efficiency is poor. For this reason, among the folders of the folder tree structure diagram that have already been created, those that can be used in common can be shared between a plurality of folder tree structure diagrams, thereby saving data capacity and efficiently performing correction work. There is a need for an apparatus or method that can be implemented.

The present invention has been made based on the above circumstances, and an object of the present invention is to provide a folder sharing apparatus and a folder sharing method capable of sharing a folder among a plurality of folder hierarchical structure diagrams. Things.

[0005]

In order to achieve the above object, a folder sharing apparatus according to the present invention provides a folder hierarchical structure diagram showing the inclusion relation of each folder on a screen. Folder data having ID information of the folder, a folder name of the folder, and, when the folder shares another folder, sharing source folder ID information which is ID information of the other folder to be shared; Storage means for storing a folder immediately before including the folder or hierarchical data indicating the folder immediately after being included in the folder, and a predetermined folder (shared source folder) already created on the folder hierarchical structure diagram Is specified, and a folder having the same folder name as the specified sharing source folder (share destination folder) When a predetermined position in the folder hierarchical structure diagram in which to create ()) is specified, the folder data having the ID information of the sharing destination folder and the sharing source folder ID information is specified for the sharing destination folder. Creating the hierarchical data based on the position to share a folder on the folder hierarchical structure diagram; and displaying the folder hierarchical structure diagram having the share destination folder on the screen. A display process of displaying the folder name of the folder data of the sharing source folder on the screen based on the sharing source folder ID information included in the folder data of the sharing destination folder. And means.

In order to achieve the above object, a folder sharing method according to the present invention provides a folder hierarchical structure diagram showing the inclusion relation of each folder on a screen. And folder name having the folder name of the folder, and when the folder shares another folder, sharing source folder ID information which is ID information of the other folder to be shared, and the folder includes the folder. Storing the folder immediately before the folder or the hierarchical data indicating the folder immediately after being included in the folder, and instructing a predetermined folder (shared folder) already created on the folder hierarchical structure diagram, Folder to create a folder (share destination folder) with the same folder name as the specified share source folder When a predetermined position in the hierarchical structure diagram is specified, the folder data having the ID information of the sharing destination folder and the ID information of the sharing source folder for the sharing destination folder, and the folder data based on the specified position. Creating hierarchical data and sharing a folder on the folder hierarchical structure diagram; and displaying the folder hierarchical structure diagram having the shared destination folder on a screen, wherein the shared Referring to the folder name of the folder data for the sharing source folder based on the sharing source folder ID information included in the folder data for the destination folder and displaying the folder data on a screen. It is assumed that.

In the present invention, since the folder data is also created for the sharing destination folder, the sharing destination folder can have ID information different from that of the sharing source folder. Therefore, since the sharing destination folder can have its own history data, the folder can be shared among a plurality of folder hierarchy diagrams. Further, since the folders on the folder hierarchical structure diagram are shared using the folder data and the hierarchical data, the data capacity can be reduced as compared with the case where the folders on the folder hierarchical structure diagram are copied. . In addition, the folder data of the sharing destination folder includes the ID information of the sharing source folder, and the folder name of the sharing destination folder is displayed on the screen with reference to the folder name of the sharing source folder. When correcting the folder name of the sharing destination folder, only the sharing source folder needs to be corrected, and the correction work can be performed efficiently.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic block diagram of a folder sharing apparatus according to an embodiment of the present invention. As shown in FIG. 1, the folder sharing device of the present embodiment
It includes a CRT display device 11, a position input device 12, a central processing unit 13, a database 14, and a storage unit 15.

The database 14 stores a plurality of information in a folder format. In the present embodiment, a case will be described in which management information on, for example, three automobiles A, B, and C is stored in the database 14. This management information includes drawing information and history information. The drawing information is, for example, drawing data of parts of each automobile, and the history information is, for example, data relating to a failure history of each part.

[0010] The folder is a container for storing programs and files. A file cannot contain a file within it, but a folder differs from a file in that it can contain folders and files within it. Each folder has a folder ID and a folder name. Thus, by storing the management information in the folder format, each management information can be systematically managed.

The storage unit 15 stores, for each folder, a folder ID of the folder, a folder name of the folder, and a folder hierarchical structure diagram showing the inclusion relation of the folders on the screen of the CRT display device 11. When the folder shares another folder, folder data having the ID of another folder to be shared (shared folder) and hierarchical data indicating the folder immediately before the folder is stored for each folder. I do.
Such a folder hierarchical structure diagram is automatically created by the central processing unit 13. In particular, in the present embodiment, a folder tree structure diagram in which the relationship between folders is represented by a tree structure is used as the folder hierarchy structure diagram. In the folder tree structure diagram, each folder is symbolized by a graphic image (icon), and the name of the folder is displayed as character information on each icon. It should be noted that creating a folder or creating a folder tree structure diagram in the database 14 can be performed using a known technique, and a detailed description thereof will be omitted here.

FIG. 2 shows an example of a folder tree structure diagram. In this example, a case is shown in which management information on the vehicles A, B, and C is managed in a folder, and files included in the folder are omitted. Management information about the automobile A is contained in the folder F _1.
Folder F _1, the folder name as the folder F ₁₁ is "history", the folder name is managed by the folder F ₁₂ is "drawing". Folder F ₁₁ is, each part α of the automobile A, is intended to put the information on the failure history of each β, the folder name as the folder F ₁₁₁ is "α", folder F folder name is "β" ₁₁₂ .
Each of the folders F ₁₁₁ and F ₁₁₂ includes folders and files therein. Also, the folder F _12, each part of the automobile A alpha, is intended for containing the drawing information about the beta, including folders and files therein.
Thus, by looking at the folder tree structure diagram, an overview of the management information contained in each folder can be easily understood.

The folder tree structure diagram for each of the cars B and C has the same configuration as the folder tree structure diagram for the car A. By the way, as long as the vehicle is used, the configuration of necessary parts is almost the same, so that the drawing information of each part of the vehicles A, B, and C is often the same. On the other hand, the history information about each part of the vehicles A, B, and C naturally differs for each vehicle. For this reason, in each folder tree structure diagram of the management information of the cars A, B, and C, even if all the folders and files under a certain folder are not the same, there are many folders having the same folder name in a part of the tree structure. May exist. For example, as shown in FIG. 2, the folder F ₂₁₁ of the folder tree structure diagram of the vehicle B and the folder F ₃₁₁ of the folder tree structure diagram of the vehicle C have the same folder name as the folder F ₁₁₁ of the folder tree structure diagram of the vehicle A. α ”. Also, the folder F ₃₁₂ of a folder tree view of folders F ₂₁₂ and the car C folder tree view of the vehicle B is has the same folder name as the folder F ₁₁₂ of a folder tree view of an automobile A to "β". In the folder sharing apparatus according to the present embodiment, as described in detail below, when a folder tree structure diagram is created, if there is a folder that can be used in common among already created folders, the folder is divided into a plurality of folder tree structures. Can be shared between figures.

The CRT display device 11 displays, for example, a folder tree structure diagram. The position input device 12 indicates position coordinates of a predetermined folder tree structure diagram or the like on the screen of the CRT display device 11, and a mouse, a trackball, or the like is used. Central processing unit 1
Reference numeral 3 has a function of sharing a folder between a plurality of folder tree structure diagrams (a sharing function) and a function of displaying the folder tree structure diagram on the screen of the CRT display device 11 (a display processing function). Specifically, the sharing function specifies a predetermined folder (shared folder) that has already been created on the folder tree structure diagram and a folder (shared folder) having the same folder name as the specified shared folder. When a predetermined position in the folder tree structure diagram in which the destination folder is to be created is specified, the ID of the sharing destination folder and the ID of the sharing source folder for the sharing destination folder
By creating folder data having the following structure and hierarchical data based on the designated position, the folder is shared on the folder tree structure diagram.

The display processing function is for displaying a folder tree structure diagram on the screen of the CRT display device 11 based on folder data and hierarchical data for each folder. In particular, when a folder tree structure diagram having a sharing destination folder is displayed on the screen, the sharing destination folder is identified based on the ID of the sharing source folder included in the folder data of the sharing destination folder. Refer to the folder name of the folder data and display it on the screen.

Next, the folder data and the hierarchical data will be described in detail. FIG. 3A is a diagram for explaining folder data, and FIG. 3B is a diagram for explaining hierarchical data. The folder data represents the contents of each folder. As shown in FIG. 3A, the folder data includes items such as “folder ID”, “folder name”, “share source folder ID”, and “number of shares”. “Folder ID” is the ID (identification information) of the folder. “Folder name” is the name of the folder defined by the user. This folder name is displayed together with the icon of the folder on the folder tree structure diagram. In particular, when the folder is a sharing destination folder, nothing is described in the item of “folder name”. “Shared folder ID” indicates the ID of the shared folder when the folder is a shared folder.
Enters. Therefore, if the folder is not a sharing destination folder, nothing is entered in the item of “sharing source folder ID”. “Shared number” indicates the number of other folders sharing the folder as a sharing source folder. If the folder is not the sharing source folder,
The item of “Number of shares” is left blank.

The hierarchical data represents a so-called parent-child relationship for each folder. Figure 3 shows the hierarchical data.
As shown in (b), items “parent folder ID” and “child folder ID” are included. The “child folder ID” contains the ID of the folder. In addition, "parent folder I
D ”is the I of the folder immediately before that folder.
D enters. For example, in the hierarchical data folder F ₁₁ in the folder tree structure diagram shown in FIG. 2, "child folder I
D "item to enter the ID of the folder F ₁₁ of the items to the ID of the folder F ₁ of the" parent folder ID "is entered. In the hierarchical data of the _first folder F1, "child folder ID"
Item to enter the ID of the folder F ₁ of, "parent folder I
Nothing enters the item of "D". The arrangement of the folders in the folder tree structure diagram is determined by the hierarchical data.

In this embodiment, since folder data is also created for a sharing destination folder, the sharing destination folder can have a folder ID different from the sharing source folder. Therefore, the sharing destination folder can have its own history data, and thus, regardless of the sharing source folder, the sharing destination folder is connected under any folder and the sharing folder is connected under the sharing destination folder. Can be specified. This is the reason that the folder sharing apparatus of the present embodiment can share folders between a plurality of folder hierarchical structure diagrams.

Next, a processing procedure for sharing a folder among a plurality of folder tree structure diagrams in the folder sharing apparatus according to the present embodiment will be described. FIG. 4 is a diagram for explaining a process of sharing a folder among a plurality of folder tree structure diagrams using a screen. Now, as shown in FIG. 4A, a folder tree structure diagram for the car A has already been created, and a folder tree structure diagram for the car B has been created halfway. In this case, the operator folder then attempts to create a folder tree view of the vehicle B is assumed to be the one that has the same folder name and folder F ₁₁₁ of a folder tree view of an automobile A. The operator, in order to share a folder F ₁₁₁ in the folder tree view of an automobile B, specific key, for example, while holding down the control key and Arutoki, using the mouse, after dragging the folder F ₁₁₁ as a shared source folder Then, the shared folder is dropped at a predetermined position in the folder tree structure diagram of the vehicle B in which the folder to be created is created. As a result, a sharing destination folder F ₂₁₁ is created at the position where the sharing source folder F ₁₁₁ is dropped, as shown in FIG.

At this time, the central processing unit 13 internally performs the following processing. That is, when dragging and dropping while performing a specific key operation, folder data and hierarchical data are newly created for the sharing destination folder _F211 . Specifically, the newly defined ID is described in the item of “folder ID” of the folder data of the sharing destination folder F ₂₁₁ . And "Shared folder ID"
The entry describes the ID of the shared source folder F _111. However, in the folder data of the sharing destination folder F ₂₁₁ , the items of “folder name” and “number of shares” are both blank. The item “child folder ID” of the hierarchical data for the sharing destination folder F ₂₁₁ includes the sharing destination folder F _211.
Enter the ID of ₂₁₁ , and in the item of “parent folder ID”,
It describes the ID of the folder F ₂₁ immediately before including shared folder F _211. As a result, folder data and hierarchical data of the sharing destination folder F ₂₁₁ are created. On the other hand, in the item of “shared number” of the folder data of the sharing source folder F ₁₁₁ , the number obtained by adding 1 to the currently described number is described. For example, if the sharing source folder F ₁₁₁ has never been shared, the “number of shares” is 1
And Thus, the process of sharing the folder ends.

Incidentally, for some folders,
Are connected continuously on the folder tree structure diagram
, The sharing process can be performed collectively. example
For example, as shown in FIG.
Folder F of ruda tree structure diagram ₁₁₁, F₁₁₂At once
When performing activation, first use a mouse to
Da F₁₁₁, F₁₁₂Specify the range. And a specific key
-While operating, use the mouse to
Is the predetermined position in the folder tree structure diagram for car B.
Drag and drop to the location. In this case, the central processing unit
13 indicates each folder F₁₁₁, F₁₁₂And the source folder
As above for the two share destination folders
Create folder data and hierarchical data respectively.

Next, a process of displaying a folder tree structure diagram on the screen of the CRT display device 11 in the folder sharing apparatus of the present embodiment will be described. When the operator presses a button for displaying the folder tree structure diagram on the screen using the mouse, the central processing unit 13 changes the folder tree structure diagram based on the folder data and the history data for each folder. It is created and displayed on the screen of the CRT display device 11. At this time, if the share folder is included in the folder tree structure diagram,
The folder data of the sharing source folder is read from the storage unit 15 based on the ID of the sharing source folder included in the folder data of the sharing destination folder. Then, referring to the “folder name” of the read folder data of the sharing source folder, the folder name of the sharing destination folder is displayed on the folder tree structure diagram.

In the folder sharing device of the present embodiment, the central processing unit, for each folder,
D, the folder name of the folder, the folder data having the ID of the sharing source folder when the folder is the sharing destination folder, and the hierarchical data indicating the ID of the folder immediately before the folder including the folder for each folder. By creating, the folder data is also created for the sharing destination folder, so that the sharing destination folder can have an ID different from that of the sharing source folder. Therefore, since the sharing destination folder can have its own history data, the folder can be shared among a plurality of folder tree structure diagrams.

Further, in this embodiment, since the folders on the folder tree structure diagram are shared by using the folder data and the hierarchical data, the data is compared with the case where the folders on the folder tree structure diagram are copied. Capacity can be saved. In addition, the folder data of the sharing destination folder includes the ID of the sharing source folder, and the folder name of the sharing destination folder is displayed on the screen with reference to the folder name of the sharing source folder. When modifying the folder name of the destination folder, only the sharing source folder needs to be modified, and the modification work can be performed efficiently.

In particular, in the folder sharing apparatus of the present embodiment, as described below, the operator performs operations such as folder sharing, deletion or modification without distinguishing between the sharing source folder and the sharing destination folder. It is possible.
Thereby, the work efficiency can be further improved. For example, in FIG. 2, it is assumed that a folder F _{211 in} the folder tree structure diagram of the car B is a sharing destination folder in which the folder F ₁₁₁ in the folder tree structure diagram of the car A is a sharing source folder. Now, again, the sharing destination folder F having the same folder name as the sharing source folder F ₁₁₁
Consider a case where ₃₁₁ is created at a predetermined position in the folder tree structure diagram of the car C. In this case, the operator may drag and drop either the sharing source folder _F111 or the sharing destination folder _F211 to a predetermined position where the sharing destination folder _F311 is to be created, while performing a specific key operation.
When the sharing operation is performed by dragging and dropping the sharing source folder _F111 , the central processing unit 13 performs the same processing as the processing described above. On the other hand, the share destination folder F
_When the sharing operation is performed by dragging and dropping the ₂₁₁ , the central processing unit 13 creates the folder data of the sharing destination folder F ₃₁₁ when creating the folder data of the sharing destination folder F _311.
In the item “D”, the folder I described in the “share source folder ID” of the folder data of the share destination folder F ₂₁₁
D is described.

When the sharing source folder is deleted, not all the sharing destination folders are deleted together, but the sharing destination folder survives as it is. In this case, when the operator presses a button for deleting the sharing source folder with the mouse, the central processing unit 13 firstly sets the item of “Number of shares” in the folder data of the sharing source folder to be deleted. Is described, that is, whether the folder is a sharing source folder or not.
If it is determined that the number is described in the “number of shares”, based on the folder data of each folder stored in the storage unit 15, the item of the “share source folder ID” is Find out all the sharing destination folders in which the ID is described. Next, the central processing unit 13 newly selects a predetermined one of the found sharing destination folders as a sharing source folder. After that, I in the item of “shared folder ID” of the folder data of the new shared folder
Erase D. In the “folder name” item of the folder data of the new sharing source folder, the folder name of the sharing source folder to be deleted is described, and in the “share number” item, the sharing source folder to be deleted is described. Enter the number obtained by subtracting 1 from the number described in “Number of shares” in the folder data of the folder. Finally, the central processing unit 13
Deletes the folder data and history data of the sharing source folder to be deleted, and rewrites the “parent folder ID” item of the history data for the folder immediately after being included in the sharing source folder to be deleted.

Further, when the folder name is corrected for either the sharing source folder or the sharing destination folder, all the folder names of the sharing source folder and the sharing destination folder are corrected. When the operator corrects the folder name of the sharing source folder, the central processing unit 13 writes the corrected folder name in the “folder name” of the folder data for the sharing source folder. On the other hand, when the operator corrects the folder name of the share destination folder, the central processing unit 13
Finds the folder data of the sharing source folder based on the “sharing source folder ID” of the folder data of the sharing destination folder. Then, the corrected folder name is described in the “folder name” of the folder data of the found sharing source folder.

It should be noted that the present invention is not limited to the above embodiment, and various modifications can be made within the scope of the invention. For example, in the above-described embodiment, a case is described in which hierarchical data having the ID of the folder and the ID of the folder immediately before the folder are used, but the hierarchical data includes the ID of the folder and the ID of the folder immediately after being included in the folder
May be used.

Also, in the above embodiment, the case where a folder is shared between a plurality of folder tree structure diagrams has been described. However, in the present invention, a folder is shared between different branches of the same folder tree structure diagram. Also applicable to cases. Further, in the above embodiment, each of the sharing source folder and the sharing destination folder may be displayed in different colors on the screen of the CRT display device.

The program for executing the operation described in the above embodiment is a floppy disk, a CD, or the like.
-The whole or a part thereof is recorded or stored in a portable medium such as a ROM or a storage device such as a hard disk. The program is read by the computer, and all or part of the operation is executed.

[0031]

As described above, according to the present invention, since the folder data is also created for the sharing destination folder, the sharing destination folder can have ID information different from that of the sharing source folder. Therefore, since the sharing destination folder can have its own history data, the folder can be shared among a plurality of folder hierarchy diagrams. In addition, since the folders on the folder hierarchical structure diagram are shared using folder data and hierarchical data,
Data capacity can be saved as compared with a case where a folder on the folder hierarchical structure diagram is copied. In addition, the folder data of the sharing destination folder includes the I of the sharing source folder.
D information is included, and the folder name of the sharing destination folder is displayed on the screen with reference to the folder name of the sharing source folder. Therefore, when correcting the folder names of the sharing source folder and the sharing destination folder, the sharing source folder is changed. Only the correction needs to be performed, and the correction operation can be performed efficiently.
