  FIG. 1 is a block diagram illustrating an example of the configuration of a system that manages the use of files. This system includes a configuration in which a file management server 10 and one or more client terminals 20 are connected via a network 30 such as the Internet or a local area network.

  The file management server 10 is a server device that manages files used in the present system. FIG. 2 shows an example of a schematic configuration of the file management server 10. 2, the file management server 10 includes a file DB 100, a user information DB 110, a communication unit 120, a file management unit 130, a user authentication unit 140, an access right management unit 150, a file list generation unit 160, and a file input / output unit. 170.

  The file DB 100 is a database that stores files to be managed by the file management server 10. The file DB 100 of this example stores files in folders (directories) having a hierarchical structure. The file stored in the file DB 100 is an electronic file including information of one or more formats among various formats such as text document data, audio data, still image data, and moving image data. In the following, a case where an electronic document file is registered in the file DB 100 will be described as an example. However, the embodiments described below may be similarly applied to other various files. Hereinafter, an electronic document file is referred to as a document file.

  FIG. 3 shows an example of a document file registered in the file DB 100. FIG. 3 shows an example of information of three document files, and one line in the table of FIG. 3 corresponds to one document file. Each document file is given a document ID which is identification information of the document file. “Storage position” in the table of FIG. 3 indicates the folder in which the document file is stored and the position of the folder in the hierarchical structure. In the example of FIG. 3, the storage locations of the three document files are all “root / folderA”. This means that the document file is stored in the folder “folderA” located under the folder “root”. The “file name” is a name given by the user to each document file. “Access right” represents the name of a user who is permitted to use each document file. “Registration date” represents the date and time when each document file was registered in the file DB 100. The form of the registration date value is not limited to the example of FIG. 3 as long as the information indicates the registration time of each document file. For example, the date and time may include not only the hour and minute but also second information, or the registration time may be represented by only the date without representing the time.

  Note that the table in FIG. 3 merely shows attribute information representing the attributes of the document file registered in the file DB 100. Each document file may have information of an aspect different from the example of FIG. 3 with respect to the attribute information shown in FIG. For example, the access right may be defined by the type of operation (viewing, editing, printing, deleting, etc.) on the document file and the subject (user or group of users) who is permitted or prohibited from that type of operation. Further, the document file may have other attribute information (for example, the creator of the document file) of the items shown in FIG. Note that the file DB 100 does not need to actually store the information table illustrated in FIG.

  Referring to FIG. 2 again, the user information DB 110 is a database that stores information about users who use this system. The user information DB 110 stores, for example, identification information and authentication information of each user.

  The communication unit 120 is an interface for transmitting and receiving information to and from the client terminal 20 connected to the file management server 10 via the network 30. The communication unit 120 passes various requests and information such as document files received from the client terminal 20 to the file management unit 130, the user authentication unit 140, the file list generation unit 160, or the file input / output unit 170, which will be described in detail later. . In addition, the communication unit 120 transmits information passed from each of the file management unit 130, the user authentication unit 140, the file list generation unit 160, and the file input / output unit 170 to the client terminal 20 as the transmission destination. To do. In the processing of each unit described below, information exchanged with the client terminal 20 is transmitted / received via the communication unit 120.

  The file management unit 130 manages files in the file DB 100. For example, the file management unit 130 writes a file to the file DB 100 and reads a file from the file DB 100. For example, when the file management server 10 receives a use request for a document file from the client terminal 20, the file management unit 130 reads out the target document file for the use request from the file DB 100 and sends it to the file input / output unit 170 described later. Then, the document file is transmitted to the requesting client terminal 20 via the communication unit 120. When the file management server 10 receives a new document file (not registered in the file DB 100) or an updated version of the document file registered in the file DB 100 from the client terminal 20, the file management unit 130 The new document file or the updated document file is acquired via 170, and the acquired document file is registered (written) in the file DB 100. When the file management server 10 receives a request for use of a document file from the client terminal 20, the file management unit 130 may request the access right management unit 150 to determine whether or not the document file can be used. The file management unit 130 causes the request source client terminal 20 to use the document file if the access right management unit 150 permits the use, and if the access right management unit 150 does not permit the use, the file management unit 130 uses the request source client terminal 20. Do not use the document file.

  The user authentication unit 140 performs user authentication with reference to the user information DB 110. For example, when the file management server 10 acquires authentication information such as user identification information and password from the client terminal 20, the user authentication unit 140 includes a combination of the acquired identification information and authentication information and a combination registered in the user information DB 110. Is matched. The user authentication unit 140 passes the verification result to the access right management unit 150.

  The access right management unit 150 manages the access right of the document file. The access right management unit 150 manages the access right of the document file using the result of user authentication received from the user authentication unit 140. For example, when receiving from the user authentication unit 140 that the user authentication has failed, the access right management unit 150 indicates that the user is not permitted to use all files registered in the file DB 100. To notify. When receiving from the user authentication unit 140 that the user authentication is successful, the access right management unit 150 determines whether or not the document file can be used in response to a request from the file management unit 130. In this case, the access right management unit 150 determines whether or not to allow the user of the requesting client terminal 20 to use the document file according to the access right set in the document file.

  The file list generation unit 160 generates a list of files registered in the file DB 100 in response to a request from the client terminal 20. For example, when the client terminal 20 requests a list of files stored in a specific folder in the file DB 100, the file list generation unit 160 notifies the file management unit 130 to that effect. Upon receiving this notification, the file management unit 130 among the document files stored in the target folder in the file DB 100, the document for which the access right management unit 150 has determined permission to use for the user of the requesting client terminal 20. The file is returned to the file list generation unit 160. The file list generation unit 160 generates a list including at least part of the attribute information (for example, a file name) of the document file received from the file management unit 130 and transmits the list to the requesting client terminal 20.

  The file input / output unit 170 passes the document file received from the client terminal 20 to the file management unit 130, and conversely transmits the document file received from the file management unit 130 to the client terminal 20.

  FIG. 4 is a block diagram illustrating an example of a schematic configuration of the client terminal 20. The client terminal 20 is a terminal device used for a user to operate a document file. 4, the client terminal 20 includes a communication unit 200, a file acquisition unit 210, a link registration processing unit 220, a file list display control unit 230, a link determination unit 240, and a storage unit 250.

  The communication unit 200 is an interface for transmitting and receiving information to and from the file management server 10 connected to the client terminal 20 via the network 30. The communication unit 200 passes the information received from the file management server 10 to the file acquisition unit 210, the link registration processing unit 220, or the file list display control unit 230, which will be described in detail later. In addition, the communication unit 200 sends various requests to the file management server 10 and the file management server 10 from the file acquisition unit 210, the link registration processing unit 220, and the file list display control unit 230 as a transmission destination. The passed information is transmitted to the file management server 10. In the processing of each unit described below, information exchanged with the file management server 10 is transmitted / received via the communication unit 200.

  The file acquisition unit 210 acquires a document file from the file management server 10 and stores the acquired document file in the storage unit 250. In other words, the file acquisition unit 210 performs a process of downloading a document file from the file management server 10. The file acquisition unit 210 receives, for example, a user input indicating a document file to be acquired via an input device (not shown) such as a mouse or a keyboard, and manages transmission of the document file specified by this input. Request to server 10. When the document file transmitted from the file management server 10 is acquired in response to this request, the file acquisition unit 210 causes the storage unit 250 to store the document file.

  The link registration processing unit 220 performs processing for generating information representing the storage position of the document file acquired by the file acquisition unit 210 in the storage unit 250 and registering it in the file management server 10. The link registration processing unit 220 of this example generates a file including information indicating the storage location of the acquired document file, and transmits the generated file to the file management server 10. Hereinafter, the file generated by the link registration processing unit 220 is referred to as a “link file”. The link file is generated corresponding to each document file acquired by the file acquisition unit 210 and registered in the file management server 10.

  FIG. 5 schematically shows an example of the structure of the link file. FIG. 5 illustrates a case where the file illustrated in FIG. 3 is registered in the file DB 100 of the file management server 10 and the file acquisition unit 210 of the client terminal 20 acquires the document file with the document ID “Doc1”. It is an example of the link file produced | generated. The link file 40 in the example of FIG. The file content 400 includes values of items of an original document, a registration date of the original document, a download file name, a download destination, and a deletion flag. The original document is a value that identifies the document file acquired from the file management server 10. The value of “original document” includes the name “Server A” of the file management server 10 and the document ID “Doc1” of the document file. The value of “original document registration date” represents the registration date (in the file management server 10) of the document file acquired from the file management server 10. In the example of FIG. 5, the registration date “2008/05/20 18:08” of the document file with the document ID “Doc1” in the table of the example of FIG. 3 is the value of “original document registration date”. The “download file name” is a name given in the client terminal 20 to the document file acquired from the file management server 10 and stored in the storage unit 250. The download file name may be the same as or different from the file name of the original document registered in the file DB 100 of the file management server 10. In the example of FIG. 5, the download file name is the same as the file name of the original document “Doc1” illustrated in FIG. The “download destination” represents the storage position of the acquired document file in the storage unit 250. The “download destination” in the example of FIG. 5 indicates that the acquired document file is stored at the storage location represented by “C: \ Users \ Tanaka \ Desktop” in the storage unit 250. The download destination may be regarded as information indicating a link to the acquired document file, that is, reference information. The “deletion flag” is a flag indicating whether or not the client terminal 20 has accepted a user input instructing deletion of the acquired document file. When the link file is generated, a value “False” indicating that an input for instructing deletion is not accepted is set as an initial value of the deletion flag. The deletion flag in the example of FIG. 5 is also set to “False”. When an input for instructing deletion of the document file is received, the value of the deletion flag of the link file corresponding to the document file is set to “True”.

  As described above, when the file acquisition unit 210 generates a link file like the example of FIG. 5 corresponding to the downloaded document, the link registration processing unit 220 transmits the generated link file to the file management server 10 together with the registration request. . When receiving the link file and the registration request from the client terminal 20, the file management server 10 registers the received link file in the file DB 100. In this example, in the file management server 10, the link file is stored in the file DB 100 in the same storage location as the “original document” of the link file.

  FIG. 6 shows an example of link file attribute information managed by the file management server 10 when the link file 40 of the example of FIG. 5 is registered in the file DB 100 of the file management server 10. FIG. 6 also shows attribute information of the three document files “Doc1,” “Doc2,” and “Doc3” illustrated in FIG. In the example table of FIG. 6, the row of the document ID “Doc4” represents the attribute information of the link file 40 of FIG. The document ID “Doc4” of the link file 40 is identification information given to the link file 40 by the file management unit 130 of the file management server 10 that acquired the link file 40. The storage location “root / folderA” of the document ID “Doc4” represents the location where the entity including the file content 400 of the link file 40 is stored in the file DB 100. As described above, the link file 40 is stored in the same storage location as the original document “Doc1”. The file name “08 patent target (final version) .txt.lnk” of the document ID “Doc4” is the download file name “08 patent target (final version) .txt” included in the file content 400 of the link file 40. It consists of a character string and a character string “.lnk” indicating that it is a link file. As described above, when registering the link file in the file DB 100, the file management unit 130 registers information for distinguishing the link file from the normal document file in association with the link file. In the example of FIG. 6, the access right value of the link file 40 is set so that only the user of the client terminal 20 who downloaded the original document of the link file 40 is allowed to access the link file 40. In this example, the user of the client terminal 20 who downloaded the original document “Doc1” of the link file 40 is “Tanaka”. Therefore, the access right value of the document ID “Doc4” includes only “Tanaka”, and does not include “Yamada” and “Suzuki” who have the access right of the original document “Doc1”. The registration date value of the document ID “Doc4” represents the date and time when the link file 40 was registered in the file DB 100.

  Returning to the description of FIG. 4, the file list display control unit 230 performs a process of acquiring the file list generated by the file list generation unit 160 of the file management server 10 and displaying the file list on a display device (not shown). The file list display control unit 230 receives, for example, an input from a user instructing to display a list of files included in a specific folder in the file DB 100 of the file management server 10 via an input device (not shown). And the file list request are transmitted to the file management server 10. Upon receiving the file list transmitted from the file management server 10 in response to this request, the file list display control unit 230 determines whether or not a link file is included in the received file list. Display information indicating the content of the screen to be displayed on the display device is generated according to the determination result. When the received file list includes a link file, the file list display control unit 230 in this example displays display information that excludes the document file (original document) corresponding to the link file from the list. Generate. For example, when the information of the table in the example of FIG. 6 is received as a list of files included in the folder “folderA” in the file DB 100 of the file management server 10, the file list display control unit 230 reads the document that is a link file. Control is performed so as not to display the information of the document file “Doc1” by generating display information that does not include the information of the original document file “Doc1” of the file of ID “Doc4”. As a result, for example, as shown in FIG. 7, the display device of the client terminal 20 includes a file with a document ID “Doc4” that is a link file, and document files “Doc2” and “Doc3” that do not correspond to the link file. And a list not including the document file “Doc1” corresponding to the link file is displayed.

  Referring to FIG. 4 again, the link determination unit 240 receives the request from the file list display control unit 230, determines whether there is a link file in the file list acquired from the file management server 10, and the determination result. Is returned to the file list display control unit 230. In this example, the link determination unit 240 checks the file name of each file included in the file list, and if there is a file name including the character string “.lnk” indicating that it is a link file, It is determined that there is a link file.

  The storage unit 250 is a storage device that stores information processed by the client terminal 20. For example, the storage unit 250 stores a document file acquired by the file acquisition unit 210 from the file management server 10. Similar to the file DB 100 of the file management server 10, the storage unit 250 may store files in a folder having a hierarchical structure.

  Hereinafter, an example of a procedure of processing performed by the client terminal 20 will be described with reference to flowcharts illustrated in FIGS. 8 and 9. In the following, the authentication information of the user of the client terminal 20 is transmitted to the file management server 10 before the processing of the procedure of FIG. 8 or FIG. 9 is started, and is performed by the user authentication unit 140 of the file management server 10. Assume that user authentication is successful.

  FIG. 8 is a flowchart illustrating an example of a procedure of processing performed when the client terminal 20 downloads a file from the file management server 10. The file acquisition unit 210 of the client terminal 20 starts the processing of the procedure in the example of FIG. 8 when receiving an input from a user who designates a document file to be downloaded. For example, when a list of files registered in the file DB 100 of the file management server 10 is displayed on a display device (not shown) of the client terminal 20, an input for instructing a document file to be downloaded is performed by a user using a mouse or the like. This is done by instructing the file to be downloaded using the input device.

  When the procedure of the example of FIG. 8 is started, the file acquisition unit 210 determines whether or not the file to be downloaded (hereinafter simply referred to as “target file”) is a link file (step S10). The file acquisition unit 210 of this example performs the determination in step S10 by confirming whether or not the character string “.lnk” representing the link file is included in the file name of the target file. If the character string “.lnk” is included in the file name, it is determined to be a link file, and if it is not included, it is determined not to be a link file.

  If the target file is not a link file (NO in step S10), a link file corresponding to the target file is generated by the link registration processing unit 220 (step S12). In step S12, first, the file acquisition unit 210 determines the download destination of the target file, that is, the storage location of the target file in the storage unit 250. The download destination may be determined by receiving user input, or a download destination set in advance as a default download destination may be used. The link registration processing unit 220 generates a link file including information indicating the download destination determined by the file acquisition unit 210 and information specifying the target file.

  When the link file is generated, the link registration processing unit 220 uploads the generated link file to the file management server 10 (step S14). That is, the generated link file and a registration request for the link file are transmitted to the file management server 10. Upon receiving the link file and registration request, the file management unit 130 of the file management server 10 registers the link file in the file DB 100. At this time, the file management unit 130 assigns a file name including the character string “.lnk” to the link file, as described above with reference to FIG. A value is set to permit access to the user of the client terminal 20 that has requested registration of the link file. Further, the file management unit 130 registers information indicating the time when the link file is registered in the file DB 100 in the file DB 100 in association with the link file.

  When the link file is uploaded, the file acquisition unit 210 downloads the target file from the file management server 10 (step S16). That is, the file management server 10 is requested to transmit the target file, and the target file transmitted from the file management server 10 in response to this request is acquired and stored in the storage unit 250. In step S16, the target file is stored in the storage position indicated by the download destination included in the corresponding link file.

  After step S16, the file acquisition unit 210 returns the download destination file as a result (step S18). For example, the target file stored in the storage unit 250 is opened in step S16, and the contents are displayed on the display device. After step S18, the process ends.

  The example of the processing procedure when the target file is not a link file (NO in step S10) has been described above. Hereinafter, an example of a processing procedure when the target file is a link file (YES in step S10) will be described.

  When the target file is a link file, the process proceeds from step S10 to step S20, and the file acquisition unit 210 determines whether a document file corresponding to the link file is registered in the storage unit 250 (step S20). For example, the determination is made by acquiring the link file as the target file from the file management server 10 and storing the “original” in the acquired link file at the storage location of the storage unit 250 indicated by the “download destination” in the acquired link file. This is done by checking whether the document represented by “document” is stored.

  If there is no document file corresponding to the storage unit 250 (NO in step S20), the link registration processing unit 220 updates the link file on the file management server 10 (step S22). In step S22, for example, the link registration processing unit 220 determines the storage position of the corresponding document file in the storage unit 250, and rewrites the determined storage position as the download destination of the target link file to the file management server 10. To request. Upon receiving this request, the file management server 10 rewrites the download destination of the target link file in accordance with this request. At this time, the file management server 10 may further rewrite the registration date of the target link file to the current date and time. After step S22, the file acquisition unit 210 of the client terminal 20 downloads the document file corresponding to the link file to be processed (step S16), returns the download destination file as a result (step S18), and the process ends. .

  If there is a document file corresponding to the storage unit 250 (YES in step S20), the file acquisition unit 210 is a document file corresponding to the link file and registered in the file DB 100 of the file management server 10. It is determined whether the file is newer than the document file stored in the storage unit 250 (step S24). In this example, the determination in step S24 is performed by comparing the registration date of the document file in the file DB 100 of the file management server 10 with the registration date of the document file in the storage unit 250.

  If the registration date in the file DB 100 of the file management server 10 is newer (YES in step S24), the file acquisition unit 210 downloads the document file from the file management server 10 (step S16). In this example, the old document file registered in the storage unit 250 is overwritten with the document file downloaded at this time.

  If the registration date in the file DB 100 of the file management server 10 is earlier (NO in step S24), the file acquisition unit 210 has not registered in the storage unit 250 in step S18 without performing the download process in step S16. A new document file (that is, a document file stored in the download destination included in the link file that is the target file) is returned as a result, and the process ends.

  FIG. 9 is a flowchart illustrating an example of a procedure of processing performed when a list of files registered in the file management server 10 is displayed on the client terminal 20. When the file list display control unit 230 of the client terminal 20 receives a user input instructing to specify a folder in the file DB 100 of the file management server 10 and display a list of files, the file list display control unit 230 receives the file management server 10. Request a list of files contained in the identified folder. When the client terminal 20 receives a list of files transmitted from the file management server 10 in response to this request, the file list display control unit 230 starts processing of the procedure of the example of FIG.

  Referring to FIG. 9, first, the file list display control unit 230 acquires a list of files transmitted from the file management server 10 (step S30). The list of files acquired in step S30 includes only files that are given access rights to the user of the client terminal 20 among the files included in the specified folder in the file DB 100. In this example, it is assumed that the file list acquired in step S30 is a list indicating the document ID, file name, access right, and registration date of each file (see FIG. 7).

  Next, the link determination unit 240 determines whether or not a link file is included in the acquired file list (step S32). The link determination unit 240 of this example determines that a link file is included in the file list if the file name includes the character string “.lnk” in the file list.

  If a link file exists in the file list (YES in step S32), the processes of steps S34 to S40 described below are performed for each link file in the file list. For example, if a file list including information of files with document IDs “Doc1” to “Doc4” shown in FIG. 6 is a display target, “Doc4” that is a link file is a processing target of steps S34 to S40.

  In step S34, the file list display control unit 230 determines whether a document file corresponding to the link file to be processed exists in the file list. For example, the file list display control unit 230 acquires the link file to be processed from the file management server 10 and searches the file list for the “original document” included in the acquired link file by performing a search in step S34. Judgment is made.

  If the corresponding document file does not exist (NO in step S34), the processing in step S34 and subsequent steps is performed on the unprocessed link file in the file list as the next processing target without performing the processing in step S36 and subsequent processing.

  If the corresponding document file exists in the file list (YES in step S34), the file list display control unit 230 deletes the corresponding document file information from the file list (step S36). In the case of the above example with reference to FIG. 6, the information of the document file “Doc1” corresponding to the link file “Doc4” is deleted from the file list.

  Next, it is determined whether or not the value of the deletion flag of the link file to be processed is “True” (step S38). If it is “True”, the information of the link file to be processed is deleted from the file list. (Step S40).

  If the value of the deletion flag of the link file to be processed is “False” (NO in step S38), the processing of step S40 is not performed, and the unprocessed link file in the file list is set as the next processing target in step S34. The following processing is performed.

  After performing the processing of step S34 to step S40 described above for each of all the link files in the file list, the file list display control unit 230 displays the resulting file list on the display device. (Step S42). For example, the file list display control unit 230 generates display information that includes information in the file list obtained as a result and defines a display mode of the information, and displays the generated display information for the display device. By outputting, the display process of step S42 is performed. In the case of the above example referring to FIG. 6, the file list of the example of FIG. 7 is displayed on the display device of the client terminal 20 as a result of deleting the information of the document file “Doc1” corresponding to the link file “Doc4”. .

  If the link list is not included in the file list acquired in step S30 (NO in step S32), the file list display control unit 230 does not perform the processing in steps S34 to S40, but in step S30. In step S42, the acquired file list is displayed on the display device.

  After step S42, the process of the procedure in the example of FIG. 9 ends.

  According to the processing of the procedure in the example of FIG. 9, a file list including link file information corresponding to the document file is displayed in place of the downloaded document file on the client terminal 20. When the user inputs an instruction to select a file to be downloaded from the file list displayed by the process of the example of FIG. 9, the process of the process of the example of FIG. 8 described above is executed.

  In the processing of the procedure of the example of FIG. 9, a link file in which the value of the deletion flag is set to “True”, that is, a link file for which the user has issued a deletion instruction for the corresponding document file is displayed as a file. Not included in the list. Therefore, even if a link file whose delete flag value is “True” and a corresponding document file are registered on the file management server 10, the existence of these files is recognized by the user who instructed the display of the file list. Not.

  In the example of the present embodiment, in the file management server 10, the access right is given only to the user who downloaded the corresponding document file for the link file. For this reason, the file list to be processed in the procedure of the example of FIG. 9 includes the link file registered in the file management server 10 as a result of the download of the document file by another user instructed to display the file list. It will never be.

  In the client terminal 20, after a document file is downloaded from the file management server 10, the downloaded document file may be deleted or updated.

  For example, when the client terminal 20 accepts an input from a user who designates a deletion by specifying a link file in the file list displayed as a result of the processing of the procedure in the example of FIG. When receiving the input of the user instructing to delete the stored downloaded document file, the link registration processing unit 220 sets the value of the corresponding link file deletion flag to “True” to the file management server 10. To set to. Upon receiving this request, the file management unit 130 of the file management server 10 sets the value of the deletion flag to “True” in the link file registered in the file DB 100. The document file corresponding to the link file is deleted from the storage unit 250 of the client terminal 20. However, the document file registered in the file DB 100 of the file management server 10 does not have to be deleted. Even if the document file remains in the file DB 100 of the file management server 10 by the process of the above-described example of FIG. 9, it is not displayed on the client terminal 20 of the user who issued the deletion instruction.

  When the document file itself registered in the file DB 100 of the file management server 10 is deleted by an instruction from a user or administrator, the link file corresponding to the deleted document file is deleted from the file DB 100.

  There are cases where the user edits the downloaded document file stored in the storage unit 250 of the client terminal 20 and instructs the file management server 10 to upload the edited document file as an updated version. At this time, the client terminal 20 transmits and registers (uploads) the updated document file in the storage unit 250 to the file management server 10. When the updated document file is uploaded, the document file before update is overwritten with the updated document file transmitted from the client terminal 20 in the file DB 100 of the file management server 10. When the updated document file is uploaded, the contents of the link file that has been given the access right to the user who instructed uploading among the link files corresponding to the document file are updated according to the updated document file. Also good. For example, in the file content of the link file, change the download file name in the same way as the file name of the updated document file, or rewrite the registration date value of the original document to the date and time when the updated document file was uploaded Or

  When only the file name of the downloaded document file stored in the storage unit 250 is updated and the content of the document file is not changed, the client terminal 20 does not upload the updated document file to the file management server 10. Alternatively, notification of the updated file name may be performed. In this example, the file management server 10 rewrites the file name of the link file corresponding to the downloaded document file and the download file name included in the link file according to the updated file name. For example, in the client terminal 20, the file name of the document file corresponding to the link file 40 (document ID “Doc4”) illustrated in FIGS. 5 and 6 is changed from “2008 patent target (final version) .txt” to “2008. When it is changed to “Yamada team patent target (final version) .txt”, the file name after the change is notified to the file management server 10. Then, the file management server 10 rewrites the download file name included in the link file “Doc4” to the updated “Yamada team patent target (final version) .txt of 2008” and also changes the file name of the link file to “2008”. "Yamada team patent target (final version) .txt.lnk". At this time, in the file management server 10, the file name of the original document “Doc1” of the link file “Doc4” may be left as the file name before the update. FIG. 10 shows an example of attribute information of a file registered in the folder “folderA” of the file DB 100 of the file management server 10 at this time. In the example table of FIG. 10, the file name of the link file “Doc4” is the file name after the update, and the file name of the original document “Doc1” is the same as the file name before the update.

  After the download file name and the file name of the link file are updated as in the example of FIG. 10, the user having the access right to the link file instructs the client terminal 20 to display the file list, and the procedure of the example of FIG. 9 When the above process is executed, for example, a file list illustrated in FIG. 11 is displayed. Referring to FIG. 11, in the file list displayed on the client terminal 20, the file name of the link file “Doc4” is the updated file name. Also, the information of the original document “Doc1” is not displayed.

  In the example of the embodiment described above, a link file is generated and registered in the file management server 10 for each user who has downloaded a document file. Therefore, the setting of the link file deletion flag value and the update of the link file accompanying the update of the downloaded document file in the client terminal 20 are also performed for each user. Thus, according to the link file registered or updated for each user, a file list is displayed on the client terminal 20 used by each user. On the other hand, even if the link file is registered or updated in the file DB 100 of the file management server 10, the attribute information (such as access right) of the original document file of the link file is not rewritten. Therefore, in the example of the above-described embodiment, the user can download the document file at the client terminal 20 of each user using the link file without rewriting the attribute information of the document file registered in the file DB 100 of the file management server 10. The file list is displayed according to the situation.

  In addition to the examples of the embodiments described above, various modifications can be considered as embodiments of the present invention. For example, in the procedure of the example of FIG. 8 described above, after the link file is generated and uploaded (steps S12 and S14) or the link file is updated (step S22), the target file is downloaded (step S16). However, the link file may be uploaded or updated after the target file is downloaded first. When the target file is downloaded first, if the target file is not a link file (NO in step S10) in the procedure of the example of FIG. 8, the target file is downloaded (step S16), the link file is generated (step S12), Processing is performed in the order of uploading the link file (step S14), and the process proceeds to step S18. If the target file is a link file (YES in step S10) and there is no document file corresponding to the storage unit 250 (NO in step S20), the target file is first downloaded (step S16) and then linked. The file is updated (step S22), and the process proceeds to step S18. If a document file corresponding to the storage unit 250 exists (YES in step S20), the target file is downloaded if the file on the file management server 10 is newer as shown in the procedure illustrated in FIG. If YES in step S24, step S16), otherwise download is not performed (NO in step S24, step S18).

  As another modification of the procedure in the example of FIG. 8, the corresponding document file on the file management server 10 is newer than the document file stored in the storage unit 250 (YES in step S24), and this new document is stored. When the file is downloaded (step S16), the old document file and the new document file may coexist without overwriting the old document file registered in the storage unit 250. In this example, the link registration processing unit 220 of the client terminal 20 may generate a link file corresponding to a new document file and register it in the file management server 10. When the link file corresponding to the new document file is registered in the file management server 10, in the process of displaying the list of files on the file management server 10 on the client terminal 20 (see FIG. 9), the link corresponding to each of the new and old document files. The file is displayed.

  In the example of the above-described embodiment, a “registration date” indicating the registration time of the document file in the file management server 10 is registered in the file DB 100, and the document file on the file management server 10 is used by using this registration date. And the document file stored in the storage unit 250 of the client terminal 20 are determined (step S24 in FIG. 8). In one modification, an “update date” indicating the time when the contents of each document file is changed (that is, updated) is further registered in the file DB 100, and in step S24 of FIG. The new and old document files are determined using this update date. In this modification, information indicating the time when the document file is newly registered in the file management server 10 may be registered in the file DB 100 as the registration date of each document file. In yet another modification, information representing the version (version) of each document file is registered in the file DB 100 instead of the registration date or the update date, or in addition to the registration date or the update date. In step S24, whether the document file is new or old is determined based on the version. That is, the version of the document file registered in the file DB 100 of the file management server 10 and the version of the document file stored in the storage unit 250 of the client terminal 20 are compared to determine in step S24 of FIG. It's okay.

  In the example of the above-described embodiment, when the client terminal 20 receives an instruction to delete the document file corresponding to the link file, the link file on the file management server 10 is not deleted, but the link file is deleted. The value of the delete flag is set to “True”. In the modification, when the client terminal 20 receives an instruction to delete the document file corresponding to the link file, the corresponding document file is deleted from the storage unit 250 of the client terminal 20 and from the file DB 100 of the file management server 10. The link file may be deleted. In this modified example, the link file does not include a deletion flag, and the processing related to the deletion flag (steps S38 and S40) is omitted in the procedure of the example of FIG. In this modification, the document file corresponding to the link file to be deleted and registered in the file DB 100 of the file management server 10 may be deleted together with the link file, or left without being deleted. You may keep it.

  In the example of the above-described embodiment, the link file and the document file are distinguished from each other by making the file name of the link file include the character string “.lnk”. As long as the information that can distinguish the link file and the document file is associated with the link file, the form of this information is not limited to the character string “.lnk” in the file name. For example, the file name of the link file may include another character string “.lnk”. Alternatively, instead of including a character string indicating a link file in the file name, information indicating whether the file is a link file may be included in the attribute information of the file.

  Further, a part of the processing of the procedure of the example of FIG. 9 executed by the client terminal 20 in the example of the above-described embodiment may be executed by the file management server 10. In this example, the file management server 10 includes a link determination unit 240, and the link determination unit 240 and the file list generation unit 160 of the file management server 10 execute the processing of steps S30 to S40 in the procedure of the example of FIG. . For example, when a request for a list of files included in a specific folder in the file DB 100 of the file management server 10 is received from the client terminal 20, the file management server 10 starts processing of the procedure of the example of FIG. The generation unit 160 and the link determination unit 240 execute the processes in steps S30 to S40. A file list generated as a result of executing this processing is transmitted to the client terminal 20 by the file list generation unit 160 via the communication unit 120. The file list display control unit 230 of the client terminal 20 that has received this file list causes the display device to display the received file list.

  In the example of the above-described embodiment and various modifications, if the link file includes the document ID of the document file that has been downloaded to the client terminal 20, the storage location of the downloaded document file in the storage unit 250 is not necessarily limited. (“Download destination” in FIG. 5) may not be included. When the link file does not include the download destination, for example, the client terminal 20 refers to the storage unit 250 using the document ID included in the link file, and selects the document file having the document ID as the document file corresponding to the link file. May be read from the storage unit 250. In this example, the document ID included in the link file serves as reference information for the document file downloaded to the client terminal 20.

  The client terminal 20 exemplified above is typically realized by executing a program describing functions or processing contents of each unit of the client terminal 20 described above on a general-purpose computer. In the computer, for example, as shown in FIG. 12, a CPU (central processing unit) 80, a memory (primary storage) 82, various I / O (input / output) interfaces 84, and the like are connected via a bus 86 as hardware. Circuit configuration. In addition, a hard disk drive (HDD) 88, a disk drive 90 for reading various types of portable non-volatile recording media such as a CD, a DVD, and a flash memory is connected to the bus 86 via, for example, an I / O interface 84. Connected. Such a drive 88 or 90 functions as an external storage device for the memory. A program in which the processing content of the embodiment is described is stored in a fixed storage device such as the HDD 88 via a recording medium such as a CD or DVD or via a network, and is installed in a computer. The program stored in the fixed storage device is read into the memory and executed by the CPU, whereby the processing of the embodiment is realized. The same applies to the file management server.
