Next, the information regarding a terminal is information which shows the transmission destination of the joint edit file mentioned above. That is, in the file collaborative editing system 100 shown in FIG. 1, the first to third terminal devices 11 to 13 participating in the collaborative editing are managed. Specifically, it may be any information that can identify the terminal device, such as the terminal IDs of the first to third terminal devices 11 to 13, or the communication address (IP address, telephone number, etc.) used for network connection. Should be held.

  Next, details of each process in the file collaborative editing system 100 configured as described above will be described below. FIG. 6 is a flowchart showing a flow of processing in the first terminal apparatus 11 shown in FIG.

  In step S601, the first file operation unit 102 detects a display setting request based on display setting information selected by the user for the electronic file. Here, the user sets one of “normal display”, “non-display”, and “confidential display” for the electronic file held in the first file storage unit 108 from the first input unit 101. To do. FIG. 7 is a diagram showing a setting screen for display setting information of an electronic file. In FIG. 7, content data 202 of an electronic file to be set is displayed on the setting screen. The user selects one of “normal display”, “non-display”, and “confidential display” display setting information for the electronic file to be set.

  In step S <b> 602, the first file operation unit 102 determines whether the display setting request is “non-display”. If the display setting request is “non-display” (Yes in step S602), the first file operation unit 102 issues an instruction to set the display setting information of the electronic file to be set to “non-display” to the first file. This is performed in the management unit 103. The first file management unit 103 writes “non-display” in the display setting information of the setting target electronic file stored in the first file storage unit 108 (step S603). If the display setting request is not “non-display” (No in step S602), the process proceeds to step S604.

  In step S604, the first file operation unit 102 determines whether or not the display setting request is “confidential display”. If the display setting request is not “confidential display” (No in step S604), the first file operation unit 102 instructs the first file management to set the display setting information of the electronic file to be set to “normal display”. Part 103. The first file management unit 103 writes “normal display” in the display setting information of the setting target electronic file stored in the first file storage unit 108 (step S607). When the display setting request is “confidential display” (Yes in step S604), the first file operation unit 102 issues an instruction to set the display setting information of the electronic file to be set to “confidential display” to the first file. This is performed in the management unit 103. The first file management unit 103 writes “confidential display” in the display setting information of the setting target electronic file stored in the first file storage unit 108 (step S605), and transitions to the process of step S606. .

  In step S <b> 606, the first file management unit 103 instructs the pseudo display file generation unit 105 to generate a pseudo display file for an electronic file whose display setting information is “confidential display”.

  In this way, display setting information of “normal display”, “non-display”, or “confidential display” is set for the electronic file stored in the first file storage unit 108 of the first terminal device 11. The For the electronic file whose display setting information is set to “confidential display”, the pseudo display file generation unit 105 generates a pseudo display file.

  Note that the first file operation unit 102 does not use the display setting selected by the user operating the first input unit 101 as it is, but instead uses the display setting for the electronic file according to conditions set in advance by the user. May be performed.

  Next, details of the generation of the pseudo display file described in step S606 of FIG. 6 will be described. FIG. 8 is a flowchart showing the flow of processing in generating a pseudo display file.

  In step S <b> 801, the pseudo display file generation unit 105 receives a pseudo display file generation request from the first file management unit 103.

  In step S802, the pseudo display file generation unit 105 refers to the content type of the electronic file for which the pseudo display file is to be generated, and determines the type of content data of the electronic file. Here, FIG. 9 is a diagram illustrating a configuration of the electronic file 201 that is a generation target of the pseudo display file. As shown in FIG. 9, the configuration of the electronic file 201 includes layout information, display setting information, a content type, and content data.

  The layout information is the display position of the content data 202 on the screen displayed on the first file display unit 104 and the second file display unit 112. The content data 202 of the electronic file 201 can be expressed as coordinate values (10, 10), for example, with the upper left of the screen 203 being (0, 0) and the lower right being (100, 100). The content type is a data format of content data such as an image, a moving image, and a document. The content data 202 of the electronic file 201 shown in FIG. 9 shows an example that is an image. Further, the electronic file may include information regarding the owner of the file.

  The information storage format of the electronic file 201 is, for example, a format in which an XML (extensible Markup Language) file and content data are combined, a format in which each information is described in the header portion of the content data, or the like.

  In step S <b> 803, the pseudo display file generation unit 105 determines an attribute necessary for editing from the content data of the electronic file 201. FIG. 10 is an extracted attribute table showing attributes necessary for editing corresponding to the content type. Here, since the content data of the electronic file 201 is an image, the pseudo display file generation unit 105 determines the attributes required for editing to be the height and width of the image based on the extraction attribute table shown in FIG. .

  In step S804, the pseudo display file generation unit 105 creates a pseudo display file that inherits attributes necessary for editing the content data of the electronic file 201. FIG. 11 is a diagram showing the configuration of the pseudo display file 301. As shown in FIG. 11, the configuration of the pseudo display file 301 includes layout information, display setting information, content type, content data, source electronic file information, and editing operation history. Here, the display setting information of the pseudo display file 301 is set to “pseudo display” indicating the pseudo display file.

  Since the content data 202 in the electronic file 201 is confidential, the actual data itself of the content data 202 is not retained in the pseudo display file 301. For example, the content data 202 is blank or “confidential content” indicating that it is a pseudo display file. Is replaced with the content data 302 including the character string. Therefore, the content data 302 is also displayed on the screen 303. The generation source electronic file information is link information of the electronic file 201 that is the generation source of the pseudo display file 301. The description of the link information is, for example, a URI (Uniform Resource Identifier) format.

  The editing operation history is an editing operation history for the content data 302 of the pseudo display file 301 in the file editing apparatus 10. In the pseudo display file 301, the editing operation history stores an editing operation on the content data 302 of the pseudo display file 301 and the time when the editing operation was performed. The information stored in the editing operation history is not limited to these, and for example, the editing operation and various information accompanying the editing operation such as the name of the user who performed the editing operation can also be stored.

  In step S <b> 805, the pseudo display file generation unit 105 writes the generation source electronic file information in the pseudo display file 301 as link information to the electronic file 201.

  In step S <b> 806, the pseudo display file generation unit 105 writes “pseudo display” in the display setting of the pseudo display file 301.
