Description

BACKGROUND OF THE INVENTION

The present invention relates to a file management system and a hierarchical structure display method of file in a computer system, and especially, to a file management system, an electronic filing system, and a hierarchical structure display method of the file in a computer which manages a file by a hierarchical management system applied to these systems.

Generally, in the computer system such as personal computers, the file system, which is installed in the operating system, manages a produced file by a hierarchical structure. This manages by hierarchically providing a plurality of folders as a storage position of the files following the root directory, and storing the produced file in some folder.

On the other hand, the electronic filing system is used to record and manage a large amount of document, which lies scattered in the office, as electronic information. This electronic filing system stores and manages in a state of which the file is classified and arranged by reading the document recorded on paper as image data with a scanner etc., and storing it in the storage position where it is hierarchically installed as a file.

The cabinet (or, called as a library and a locker, etc.), the folder (or, called as a binder), and the document, etc. are used as a storage position of the file in this electronic filing system.

In the computer system such as personal computers, since there is no function to visually display the hierarchical structure of the file when the produced file is retrieved, it can not visually understand and confirm how many layers and which folders the retrieved file is stored, furthermore, where the file is located in the hierarchy of the system in which the folder storing the file is hierarchically managed, and, how the hierarchical structure of an upper folder of the folder is constructed.

Similarly, since the function to visually display the hierarchical structure of the storage position of the retrieved file in the electronic filing system is not installed, it is difficult to understand intuitively which document is stored in which folder of which cabinet is the retrieved file.

BRIEF SUMMARY OF THE INVENTION

An object of the present invention is to provide a file management system, an electronic filing system, a hierarchical structure display method of the file, and computer readable recording medium recording program in which function thereof is executable in the computer system which can visually and comprehensibly present the position where the file is stored for the user, when file, which is hierarchically stored, recorded and managed, is retrieved.

A file management system in a computer having a file system, which manages by a hierarchical management system, comprises: file retrieval condition specifying means to specify file retrieval condition; file retrieval means to retrieve files based on a specified retrieval condition specified by the file retrieval condition specifying means; retrieval result display means to display a retrieval result of files by the file retrieval means; file selection means to select one file among files displayed by the retrieval result display means; and display means to display path information by which the storage position of the file selected by this file selection means is shown by the tree form.

The position where the selected file is stored can be visually and comprehensibly presented for the user by the file system as a result of the retrieval of the file.

Moreover, an the electronic filing system, which manages files by a hierarchical management system, comprising: a database to manage storage position information which indicates the storage position of the file and retrieval information to retrieve the file; file retrieval condition specifying means to specify file retrieval condition; file retrieval means to retrieve files based on a specified retrieval condition; retrieval means to retrieve files which coincide with a retrieval condition specified by the file retrieval condition specifying means; retrieval result display means to display files retrieved by the retrieval means; file selection means to select one file among files displayed by the retrieval result display means; and display means to display a path information which indicates a storage position of the selected file by a tree form based on the storage position information on the file selected by the file selection means.

DETAILED DESCRIPTION OF THE INVENTION

Hereafter, the embodiment of the present invention referring to the drawing will be explained.

The configuration of the electronic filing system according to the first embodiment of the present invention is shown in FIG. 1 . This electronic filing system 11 manages document information in which the figure, the image, and the text, etc. are converted in electronic form, by a hierarchical management system of cabinet-folder-document-page-revision page, and is achieved as executable software in a usual computer system.

The computer system in which electronic filing system 11 is executed, is constructed by the computer main body 1 , the display monitor 2 , input device 3 such as the keyboard and the mouse, and scanners 4 , etc. as shown in FIG. 1 . The computer main body 1 is constructed by CPU and the hard disk drive as main memory and the secondary memory etc., and software, which constructs electronic filing system 11 is loaded on main memory as an application program, and executed by CPU.

Electronic filing system 11 of this embodiment is constructed by database 111 , real file group 112 , registration module 113 , retrieval module 114 , display module 115 , input module 116 , scanner input section 117 , and file input section 118 , etc. as shown in FIG. 1 .

Database 111 stores the hierarchical structure management information to manage the document information by a hierarchical management system of cabinet-folder-document-page-revision page. This database 111 is constructed on the storage medium such as hard disk drives installed for example in the computer main body 1 . Real file group 112 is a set of the real data registered to this electronic filing system 11 . Real data is constructed by the image data file obtained by reading with scanner 4 . Each file in real file group 112 is respectively managed by the unit of page. The page mentioned here is one file, and for example, one file among a plurality of drawing files (for example, file of the “****.tif” form) which is read with the scanner and one document file among a plurality of document files (for example, file of the “****.txt” form) are expressed as a page, respectively.

Registration module 113 is used to register real data to electronic filing system 11 , and registers the image data file obtained by being read from scanner 4 to real file group 112 . When real data is registered, registration module 113 registers the management information to database 111 so that the registered individual file is managed as a page. Reading the image data from scanner 4 is performed through scanner input section 117 .

Retrieval module 114 retrieves the page, the document, and the folder which coincide with the retrieval condition input by the user by using retrieval information stored in database 111 . Text information etc. to retrieve the page, that is, real data in all sentences in addition to title information as the key word added to the page, the document, and the folder respectively as tag are used as retrieval information. Information of the retrieval result is passed to display module 115 , and is displayed on the screen if necessary.

Display module 115 is used to display the file operation screen of this electronic filing system on the monitor 2 , and has tree display function to visually display hierarchical management system by tree form such as cabinet-folder-document-page-revision page. This tree display is performed according to the hierarchical structure management information of database 111 , and can visually display not only the hierarchy to the cabinet-folder-document but also relationship to the page which exists in the document and page in the document by the tree form. Moreover, the relationship of the page and the revision page can be displayed by the tree form about the page where the revision page exists. In addition, the tree display to visually display the hierarchical structure of the storage position on the page is performed about the page retrieved by retrieval module 114 .

Input module 116 is used to accept various operation instructions from the user, and various operation instructions such as registration, retrieval, and display, etc. are sent to the corresponding module.

HIERARCHICAL MANAGEMENT STRUCTURE OF ELECTRONIC FILING SYSTEM

An example of the hierarchical structure used with this electronic filing system 11 is shown in FIG. 2 . Document information is managed by the hierarchical structure of cabinet-folder-document-page-revision page in this electronic filing system 11 as mentioned above. “Page” corresponds to the file which is real data, and each file, which exists in real file group 112 , is managed as a page.

The storage position to store the page is “Document”. Therefore, storage position “Document” becomes one document information which is constructed from an individual page which exists there, that is, becomes a document which should be referred to the unit if it is seen from the user.

In FIG. 2 , three documents of “Document A”, “Document B”, and “Document C” are produced as page storage position. “Document A” is constructed from three pages of page 1 to page 3, “Document B” is constructed from two pages of page 1 and page 2, and “Document C” is constructed from three pages of page 1 to page 3.

“Folder” is a storage position to classify and store a lot of “Document”, and it may be called as “Binder”. In this example, “Document C” is classified in “Folder B” and “Document A” and “Document B” are stored in “Folder A”, respectively, among three documents of “Document A”, “Document B”, and “Document C”. Storage position of these folders is “Cabinet” (or, called as a library and a locker, etc.). In this example, two cabinets of “Cabinet A” and “Cabinet B” are prepared in the root directory of electronic filing system 11 , and “Folder A” and “Folder B” are stored in “Cabinet A”.

The hierarchical structure management information to manage such management system exists in database 111 , and real data corresponding to each page exists in real file group 112 .

Since “Document” is a set of one or more pages, an appropriate name (document name) to each “Document” is added.

HIERARCHICAL STRUCTURE SEEN FROM FILE SYSTEM

The actual directory configuration managed on the file system of the operating system is shown in FIG. 3 . “Installation Dir” is a directory in which the software of electronic filing system 11 is installed, and this corresponds to the root directory of FIG. 2 . The directory of “Cabinet” exists in the lower level of “Installation Dir”, the directory of “Folder” exists in the lower level than that, and, in addition, the directory of “Document” exists in the further lower level. In directory “Document”, page directory, which corresponds to the number of pages which constructs the “Document”, exists. Three page directories of “Page 1 Dir”, “Page 2 Dir”, and “Page 3 Dir” are produced in directory “Document” when the document is constructed three pages from page 1 to 3 as shown in the figure.

The file of real data corresponding to the page is stored in each page directory. Only one file is stored in the page directory in which the page where the revision page does not exist. On the other hand, a file corresponding to each revision page and the file corresponding to the page of the latest version are stored in the page directory about the page where the revision page exists. In FIG. 3 , “Page 1 Dir” is page directory including the revision page.

Moreover, the database file group is installed in directory “DB” installed in “Cabinet” directory, and corresponds to the hierarchical structure management information managed by database 111 .

EXAMPLE OF HIERARCHICAL MANAGEMENT STRUCTURE OF ELECTRONIC FILING SYSTEM

A specific use example of a hierarchical management system of cabinet-folder-document-page-revision page is shown in FIG. 4 . Here, the cabinet “Patent information” is prepared, and “Electricity” folder and “Software” folder are prepared as a folder for the document classification management. The document “A001 patent document” and “A002 patent document” is prepared in the “Electricity” folder, and files of the product catalog which publishes relating product information, the Unexamined Japanese patent application, and the Japanese Patent, etc. is registered in each document as a page. The latest version becomes a basic page when the revision version is produced by the file update etc. of the product catalog, and the old edition is managed as a revision version concerning the basic page.

Thus, since the management of the page is performed by “Document” which is the storage position of the page corresponding to real data, the registration of the page which is real data is always performed to “Document” in this electronic filing system.

If a computer readable storage medium, to which the computer program, which includes the processing procedure of electronic filing system 11 of this embodiment is recorded, is prepared, since all of electronic filing system 11 of this embodiment is achieved with software, the effect same as this embodiment can be achieved only by the introducing the computer program into a usual computer through the storage medium.

SECOND EMBODIMENT

Next, the second embodiment of present invention will be explained. The second embodiment retrieves the file to which the file system manages in the computer system, and is concerning the file management system which displays the hierarchical structure by which the storage position of the selected file is shown by the tree form from among the retrieved files.

FIG. 10 is a block diagram which explains the function configuration of the file management system in the computer system according to the second embodiment.

In FIG. 10 , input device 408 , the keyboard, and the mouse, etc., and display monitor 407 are connected with the computer main bodies 401 such as PC servers and personal computers. For example, the magnetic disk unit (not shown in the figure) is included to the computer main body 401 as a recording device which records the file.

The reference numeral 404 indicates an operating system with the window display function as a GUI(graphical user interface). File system 405 is installed to manage the record and the reproduction of the file To kernel 404 of this operating system 402 for the magnetic disk unit (not show in the figure) of this computer system. File management table 406 , which records the position etc. where the file is recorded, is installed in this file system 405 to manage the file at file recording device of magnetic disk unit etc. This file management table 406 is called the file allocation table and mastering file table, etc. in general, the structure is known in general already widely, and a detailed explanation is omitted. File system 405 hierarchically manages the files by using file management table 406 .

The reference numeral 403 indicates a file management application program from which the operation is started by the user, and, in general, it is called the file manager and the explorer. The retrieval function of the file is installed in this file management application program 403 . This file retrieval function presents the position (path information) where the file, which the user is looking for by specifying the file name and the date which the file is recorded and the text, etc. included in the file for a retrieval condition, is recorded.

The state that this file management application program 403 is started, and the screen of the file retrieval function is displayed in display monitor 407 is shown in FIG. 12 . This screen is constructed by retrieval information input area 411 , retrieval result list display area 412 , and tree display area 410 . The area where the file name which is the retrieval condition is input, the area where the text is input, the button which specifies the retrieval starting, and the button, which specifies the cancel of the retrieval, are displayed in retrieval information input area 411 . Retrieval result list display area 412 is an area where the hit file, as a result of the retrieval, is having a look displayed, and the one to display the update date of the sequence number, the file name, the size of the file, the file type, and the file of the hit file. Path information, which shows the record position in the file recording device of the file, is hierarchically displayed about the file selected with the mouse among hit files that the list display is done in retrieval result list display area 412 , in tree display area 410 .

The file, which the user is looking for, is retrieved as follows by the use of the file retrieval function of file management application program 403 , path information on the file is explained, and the operation explanation when the tree is displayed (hierarchical structure display) will be explained by using the flowchart of FIG. 11 .

First, the user starts file management application program 403 with an input device (step S 501 ). When this program starts, the screen shown in FIG. 12 is displayed in display monitor 407 .

Next, the retrieval condition of the file recording device is input to the area of the input of retrieval information on the display screen. The state that “*.TXT” is specified for a file name and “DEEF” is specified for text information is shown in FIG. 12 as a retrieval condition. When the retrieval condition is input like this, the retrieval of the file is executed by selecting the retrieval starting button the with mouse (step S 502 ).

File management application program 403 passes the specified retrieval condition to file system 405 and requests the retrieval of the file when the retrieval of this file is directed. File system 405 passes information on the file which coincides with the retrieval condition (path information etc. on the file name and the file) referring to file management table 406 based on the condition specified from file management application program 403 to file management application program 403 . File management application program 403 displays file information which is retrieval result received from file system 405 to retrieval result list display area 412 . FIG. 12 shows the case where a part of the retrieval result is displayed in retrieval result list display area 412 as this retrieval result. To display other retrieval results, the display becomes possible by clicking the arrow button shown at the right of retrieval result list display area 412 with the mouse and making the screen scrolled (step S 503 ).

Next, the desired file is selected with the mouse from among the retrieval result of the display in retrieval result list display area 412 . In FIG. 12 , the state that the file of file name “XYZ.TXT” of sequence number 5 is selected is shown in the figure (step S 504 ).

When the file is selected like this, file management application program 403 displays path information which indicates the position where the selected file is stored in the tree (hierarchical structure display). The position where the file of this selected file name “XYZ.TXT” is stored is displayed in tree form in tree display area 410 of FIG. 12 . That is, the file of selected file name “XYZ.TXT” to be recorded in the folder of the name called as BBB which is installed in the folder of the name called as AAA installed under C drive and to be managed is shown in the figure. When path information, which displays in tree form, is shown in the text, it becomes “C:\AAA\BBB\XYZ.TXT”. (On the computer which uses the operating system of an English display, the sign: back-slash “\” is used instead of sign “¥”)

As mentioned above, the user comes to be able to visually confirm path information which shows the position where the necessary file is stored from among the files managed by the hierarchical structure by displaying the hierarchical structure of the file selected from the result of doing the file retrieval in tree form. The storage position can be recognized intuitively and more in detail compared with displaying path information in the text according to the present invention. The present invention has a larger effect to recognize the storage position, especially, when the target file is stored in the folder allocated at a hierarchical deep position of lower level of the hierarchical structure.

In the hierarchical structure display method according to the second embodiment, it is also possible to store and distribute a computer program in which the procedure therefor is included to a computer readable storage medium.

Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the present invention in its broader aspects is not limited to the specific details, representative devices, and illustrated examples shown and described herein. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
