  The file storage unit 24 is composed of a hard disk device or the like, and stores electronic files (documents, tables, drawings, etc.) managed by the document management server 20 in folders.

The user or the administrator can create a folder in the folder, and can classify the file to be registered, for example, by use. As shown in FIG. 4A, in this embodiment, “general folder”, “group folder”, and “personal folder” can be created.

  The general folder can be accessed by all users who use the document management system 100, and all users who use the system can operate files in the general folder. Therefore, all users who use this system can share files in the general folder.

  The group folder can be accessed by a specific plurality of users using the document management system 100, and the specific plurality of users using the system can operate files in the group folder. Therefore, a plurality of specific users who use this system can share files in the group folder.

  The group folder is created by the system administrator at the start of system operation. At the same time or later, the system administrator sets the users who can use the group folder, and then the users who can use the group folder can freely create and delete folders and files in the group folder. Can do.

  The personal folder is a folder that only the user himself can access. This folder is automatically created in the file storage unit 24 when logging in using the information terminal 10 for the first time. A personal folder may be created in advance in the initial state. However, in this embodiment, a personal folder is created when logging into the document management server 20 for the first time.

  The document management server 20 restricts users of electronic files and electronic folders based on an ACL (Access Control List). Here, the ACL includes information such as the file ID of the electronic file (or the folder ID of the folder) and the content of access restriction as shown in FIG. 4B, for example.

  In the present embodiment, in the initial state, the right to access a general folder or an electronic file in the general folder is given to all users who use the system. Further, the access right of the personal folder or the electronic file in the personal folder is given only to the user corresponding to the personal folder. Further, the access right of the electronic file in the group folder or the group folder is given to the user registered in the group corresponding to the group folder.

The authentication information is information for identifying the user and includes a user ID, a password, and the like.

  Next, operations according to the embodiment of the present invention will be described with reference to FIGS.

  First, an information terminal file display process performed by the information terminal 10 will be described. The information terminal 10 performs user authentication and establishes a connection with the document management server 20. Then, the information terminal 10 requests and receives information about the folder from the document management server 20. Then, the information terminal 10 displays information about the folder.

  Hereinafter, the flowchart of the information terminal file display process shown in FIG. 5 will be described.

  First, when the CPU 11 accepts an input to connect to the document management server 20 from the user via the operation unit 15, the CPU 11 displays a login screen 300 as shown in FIG. 6 and accepts a login name and a password (steps). S101).

  When the user inputs a login name in the login name input field 301 and a password in the password input field 302 via the operation unit 15, the CPU 11 connects to the document management server 20 (step S102), and the input login name and password are input. Are transmitted to the document management server 20.

  When receiving the login name and password, the CPU 21 of the document management server 20 performs user authentication by determining whether or not the login name and password stored in the management information storage unit 26 match (step S103).

  The CPU 21 of the document management server 20 transmits information on the folder stored in the file storage unit 24 to the information terminal 10. The information terminal 10 receives the information regarding the folder transmitted by the document management server 20 (step S104).

  The CPU 11 of the information terminal 10 displays information about the received folder (step S105).

  In this way, the information terminal 10 authenticates the user, receives information about the folder from the document management server 20, and displays it.

  Next, the document management server file movement process performed by the document management server 20 will be described.

  For example, if an electronic file created by a user in a general folder is moved to a group folder or personal folder that the user cannot access, the user cannot use the created electronic file, which is inconvenient.

  Therefore, in the document management server file movement process of this embodiment, it is prohibited to move an electronic file from a general folder to a group folder, from a general folder to a personal folder, or from a group folder to a personal folder.

  In brief, the document management server 20 receives a file movement request from the information terminal 10, and when the movement is to a folder where movement is not prohibited, the document management server 20 permits the movement of the file and prohibits the movement. In the case of moving to a designated folder, file movement is prohibited.

  Hereinafter, a flowchart of the document management server file movement process shown in FIG. 7 will be described.

  When the CPU 21 receives a file move request from the information terminal 10, the requested file move is performed from a general folder to a group folder, from a general folder to a personal folder, or from a group folder to a personal folder. It is discriminate | determined whether it is (step S201).

  When it is determined that the requested movement of the electronic file is not movement from the general folder to the group folder, movement from the general folder to the personal folder, or movement from the group folder to the personal folder (step S201; No), the CPU 21 Executes movement of the requested file (step S202).

  CPU21 transmits the information regarding the updated folder to the information terminal 10 (step S203).

  When it is determined that the requested movement of the electronic file is movement from a general folder to a group folder, movement from a general folder to a personal folder, or movement from a group folder to a personal folder (step S201; Yes). The CPU 21 does not move the requested file, but transmits a notification to that effect (step S204). The information terminal 10 receives the notification from the document management server 20 and displays a pop-up 400 as shown in FIG.

  In this way, it is possible to prevent inadvertent movement of electronic files between folders by prohibiting movement from a general folder to a group folder, movement from a general folder to a personal folder, or movement from a group folder to a personal folder. It is possible to limit, and no inconvenience is given to the user.

  In addition, this invention is not limited to the said embodiment, A various deformation | transformation and application are possible.

  In the above embodiment, the document management server 20 determines whether or not the file can be moved. However, the information terminal 10 may determine whether or not the file can be moved.

  Information terminal file transfer processing performed by the information terminal 10 in that case will be described. When the CPU 11 of the information terminal 10 receives an input of file movement from the user via the operation unit 15, if the movement is to a folder that is not prohibited, the CPU 11 permits the movement of the file and moves to the prohibited folder. In the case of moving, file movement is prohibited.

  Hereinafter, the flowchart of the information terminal file movement process shown in FIG. 9 will be described.

  When the CPU 11 of the information terminal 10 receives an input of file movement from the user via the operation unit 15, the requested file movement is the movement from the general folder to the group folder, the movement from the general folder to the personal folder, or It is determined whether or not the movement is from a group folder to a personal folder (step S301).

  When it is determined that the movement is from the general folder to the group folder, the movement from the general folder to the personal folder, or the movement from the group folder to the personal folder (step S301; Yes), the CPU 11 as shown in FIG. A pop-up 400 is displayed (step S305).

  When it is determined that the movement is not from a general folder to a group folder, from a general folder to a personal folder, or from a group folder to a personal folder (step S301; No), the CPU 11 transmits a file movement request. (Step S302).

  Next, the CPU 11 receives information regarding the updated folder (step S303).

  The CPU 11 updates the display to the updated folder (step S304).

  In this way, if the information terminal 10 determines whether or not the folder can be moved, the processing relating to the file movement can be speeded up.
