Description

  The present invention relates to a file sharing apparatus for sharing a file via a network among a plurality of users having different attributes.

In general, a plurality of users share and use a file stored in a server installed in a data center or the like via a network.
For example, as shown in the following non-patent documents, sharing settings are made on a folder to be shared (also referred to as a “directory”) in a file area assigned to each user on the server, and browsing and editing by a sharing partner can be performed. There are ways to make it possible.

[TIPS] Setting of access right in Windows file server (https://cloud-news.sakura.ad.jp/2016/05/24/filesserver-windows-server-on-sakulude-2/) 01) Setting of WebDAV (file sharing system) (https://www.rapidsite.jp/support/guide_migration/reference/webdav/e_11370.html)

However, the above sharing method has at least one of the problems described below.
(1) The sharing target cannot be set flexibly.
Each user has different types of folder division criteria (management policies) for storing files (for each project, for each customer, for each time, for each urgency, etc.), and the priority of the criteria also differs.
Therefore, in the method 1, when there is a folder or a file that is not desired to be shared downstream of the folder in which the file to be shared exists, sharing in folder units may not be possible.
In this case, the user must manage the files in the original folder and the shared folder separately by creating a separate shared folder and copying the shared folder or file to the shared folder. I had to.
(2) The hierarchical structure of the folder is grasped.
Some users have a need not to be aware of the folder hierarchy by the sharing partner.
In this case, in the method of using the real folder assigned to the user as a shared area and providing a shortcut to the shared area to the sharing partner, the path of the shared area is disclosed and the hierarchical structure of the folder becomes clear. The above needs cannot be met.

  Therefore, an object of the present invention is to provide a means in which file management in the shared area is not restricted by the management policy of each user and the need for confidentiality of the hierarchical structure.

The first aspect of the present invention has been made to solve the above problems is a file sharing system for performing file sharing over a network between a plurality of users, the file sharing system, on Linux (registered trademark) Server there, together with the file sharing system is constituted by a WebDAV, comprising at least storage means, said storage means, Ri file area der assigned to each user, with any folder hierarchy corresponding to each user at least it has a user area, in a predetermined folder in the user area of a user, Ri tare symbolic link arranged to the real folder or real files outside the user area, the symbolic link "ln command - s option "allows the real folder or file to be viewed and edited without duplication. Characterized in that to enable.
In the second invention of the present application, in the first invention, an actual folder or file outside the user area is stored in a user area of a user different from the user where the symbolic link is arranged. Features.
Further, according to a third invention of the present application, in the first invention, the storage means further includes a shared area that is a file area managed by an administrator, and an actual folder or file outside the user area is It is stored in the shared area .

According to the present invention, at least one of the effects described below is achieved.
(1) Flexible data sharing is possible without affecting the file management policy of each user.
(2) Since an actual folder or file to be shared is provided to each sharer through a symbolic link, the user's own folder hierarchy is not grasped by the other party.

The image figure which shows the structure of the file sharing apparatus which concerns on this invention. 1 is an image diagram illustrating a configuration of a file sharing apparatus according to Embodiment 1. FIG. FIG. 2 is an image diagram illustrating an example of use of the file sharing apparatus according to the first embodiment. FIG. 6 is an image diagram illustrating a configuration of a file sharing apparatus according to a second embodiment.

  Embodiments of the present invention will be described below with reference to the drawings.

<1> Overall Configuration FIG. 1 shows an outline of a file sharing apparatus according to the present invention.
The file sharing apparatus A is an apparatus for realizing a file sharing service provided by the administrator X, and can share a file with the user terminal B used by each user Y via the network C.
The file sharing apparatus A according to the present embodiment is configured by a part or all of the elements constituting the server composed of a computer, and has at least a storage unit.
The storage unit A1 includes a known storage device or storage medium such as an HDD, SSD, or CD-ROM.

<2> Configuration of Storage Unit FIG. 2 shows the configuration of the storage unit of the file sharing apparatus according to the present invention.
In the storage means A1 of the file sharing apparatus, an administrator X that provides a file sharing service and a plurality of users Y who use the service are in a state in which file areas are allocated in the storage means A1.
In the file area allocated to the administrator X, a shared area X1 for storing an actual folder or an actual file to be shared among the users Y is provided.
Each user Y is provided with a user area Y1 which is a file area allocated individually.
Furthermore, a symbolic link 30 for an actual folder or file in the shared area X1 is arranged under each user area Y1.
Details of each component will be described below.

<3> User Area The user area Y1 is a file area assigned to the user, and is an area where a user can store a folder or file.
The user area Y1 is appropriately generated and designed by the user himself / herself according to the management policy of the user Y, the administrator generates and / or designs the user area according to the user's request, or the administrator generates and designs the user area uniquely. Can be.
In FIG. 1, a real folder (user folder 10) having a hierarchical structure (tree structure) is constructed in the user area, and real files are stored in the user folder 10.

<4> Shared Area The shared area X1 is a file area that can be managed by the administrator, and is an area for storing a real folder or a real file to be shared.
The shared area X1 can be generated and designed by the administrator according to the user's request, or can be generated and designed by the administrator.
In FIG. 2 , a shared folder having the name “c1” is constructed in the shared area X1, and files having the names “d1” and “d2” are stored in the shared folder.

<5> Symbolic Link The symbolic link 30 is a link means for virtually displaying a folder or a file under the user area Y1 and in the shared area X1.
The symbolic link 30 is also referred to as a soft link in a broad sense, in order to leave the files and folders handled on the computer disk in their original locations but to place them in a different location or to give them an alias. Therefore, the symbolic link 30 has no entity unlike the copy, and the operation on the file opened by the symbolic link 30 is also reflected in the actual file.

In FIG. 1, the symbolic link 30 of the shared folder 20 named “c1” in the shared area is arranged under “¥ a1 ¥ b1” of the user folder 10 for one user Y (left side) and the other user In Y (right side), the user folder 10 is arranged under “¥ b1 ¥ a1”.
As a result, the shared folder 20 having the name “c1” constructed in the shared area X1 and the files 21 “d1” and “d2” stored therein are connected to the virtual folder 40 and the virtual file via the symbolic link 30. 41, each user Y can view and edit.

<5.1> Symbolic Link Method In the present invention, in the Linux (registered trademark) server, when the file sharing method is WebDAV and the “ln command -s option” is used as the command of the symbolic link method, the administrator The symbolic link 30 of the shared area X1 generated in the X file area could be set under the user area Y1 of each user Y.
On the other hand, the file sharing method is set to Windows file sharing in the Windows (registered trademark) server and the “mklink command / D option” is used for the symbolic link method command, or the file sharing method is set to SMB file sharing in the Linux server. When the “ln command -s option” is used as a command of the symbolic link method, the symbolic link 30 of the shared area X1 generated in the file area of the administrator X is set under the user area Y1 of each user Y. I couldn't.

<6> Main body for generating each area The above-described generation process for each area may be manually executed by the administrator X or each user Y who manages the file sharing apparatus according to the present invention. When specific input information is given to the file sharing apparatus by Y, it may be automatically executed by a program installed in advance in the file sharing apparatus.
In the latter case, the program automatically generates at least three areas (user area generation means, shared area generation means, virtual area generation means) in response to a request from the administrator X or each user Y. ).

<7> Usage example (file sharing between departments)
Hereinafter, with reference to FIG. 3, illustrating more specific use image file sharing device according to the present invention.

<7.1> Folder Configuration on the User Side FIG. 3 shows a file between the two on the company file server assuming that one user is the planning department, the other user is the sales department, and the administrator is the system management department. The image figure at the time of sharing is shown.
In the user folder 10, the planning department has folders for “estimate each part” and “new business” in the upper hierarchy, and “sales department”, “technical department”, “general affairs department”, etc. below the “estimate each part” folder. There is a folder for each department.
In the user folder 10, the sales department provides “project” and “customer information” folders in the upper hierarchy, and “project (confidential level 1)” and “project (confidential level) are located below the“ project ”folder. Level 5) ”and the like are provided for each secret level.
For example, if you want to share “Project (1)” under the “Project (Confidential Level 1)” of the Sales Department with the Planning Department, simply provide the Planning Department with a shortcut for “Project (1)”. In the method, the planning department knows that the shared path is “\ project \ project (confidentiality level 1) \ project (1)”, and the planning department user conceals the sales department from the folder name. It can be estimated that folders are divided for each level and that other secret level project folders are stored directly under “¥ project”.

<7.2> Generation of Shared Area and Virtual Area Therefore, the administrator belonging to the system management section can use the file area allocated to the system management section in response to a request for sharing between the departments as described above. A shared folder 20 composed of an actual folder of “Project (1)” is created in a certain shared area.
Next, the administrator generates a symbolic link 30 of the shared folder 20, and arranges the symbolic link 30 in a predetermined hierarchy of the user folder 10 in each user area Y1 for the sales department and the planning department. A folder 40 is constructed.
In the planning department, the virtual folder 40 composed of the symbolic links 30 is arranged in “¥ each part approximate ¥ sales department”.
On the other hand, the sales department places the virtual folder 40 composed of the symbolic link 30 in “¥ project ¥ project (secret level 1)”.
The initial arrangement of the virtual area can be configured to be arranged at a specific position in the folder hierarchy of each department by the system management unit (administrator side).
Even if the user (sharer side) subsequently changes the location of the symbolic link, the symbolic link 30 is not interrupted.

<7.3> Summary According to the above configuration, from any department, the hierarchy is advanced to "Project (1)" divided into folders according to the management policy of the own department, and the file is changed in that folder. -Since it can be modified, there is no need to manage folders and files to be shared twice.
In addition, the data management policy of the own department is not grasped by the sharing partner.

FIG. 4 is an image diagram illustrating the configuration of the file sharing apparatus according to the second embodiment.
In the first embodiment, the actual folder or file to be shared is stored in the shared area X1, but in this embodiment, the symbolic link 30 related to the actual folder or file in the user area Y1 of the user Y is stored. Are arranged in the user area Y1 of the other user Y ′ who is the sharing partner.
In this case, first, one user Y passes the basic information including the real folder or file path (\ a1 \ b1 \ c1) to be shared stored in the user area Y1 to the administrator side.
On the administrator side, a symbolic link 30 is generated from the basic information 31 by a program manually installed by the administrator X or pre-installed in the file sharing apparatus A, and the user area Y1 assigned to the sharing partner user Y ′. Place in.
In FIG. 4, symbolic link generation and placement work is automated by a program executed by the control means A <b> 2 including a CPU or the like provided in the file sharing apparatus.

  According to the present embodiment, an actual folder or file in the user area Y1 of the user Y can be viewed and edited in the user area Y1 of the other user Y '.
