DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a file management apparatus and a program for managing a copy file copied to a plurality of external devices connected via a communication network and an original file identical to the copy file. About.

[0002]

2. Description of the Related Art Conventionally, Microsoft's Wi
There is a function known as briefcase in the windows OS. The briefcase function has a function of keeping both the original file and the copy file updated. For example, when data is exchanged between two personal computers A and B, first, the original file on the hard disk (HDD) of the personal computer A is copied into a briefcase, and the briefcase is copied to a floppy disk (FD). Or other portable storage media (usually,
Open the briefcase of the FD with the personal computer B, edit the copy file in the FD, instruct the update, update the briefcase contents, and return the briefcase to the personal computer A. When the update instruction is issued, the original file on the HDD of the personal computer A is updated. If the file of the personal computer A has been updated by that time, the copy file in the briefcase is updated. This function is available for LAN (local area net
Work can be similarly applied to files in briefcases in a shared folder on a local information communication network.

[0003] A LAN is a network system that allows computers installed in relatively small areas such as offices and buildings to exchange data and share peripheral devices such as printers. Among them, there are various standards for each connection method, wiring type, and communication procedure, and currently, the standard that complies with Ethernet is the most representative. This means that multiple PCs with LAN boards are connected with a twisted pair cable around a hub, and files can be exchanged between PCs.
A typical usage is to use data in the hard disk of one personal computer. Such L
In AN, a personal computer that discloses a hard disk to everyone is called a “server” or a “host”.

[0004] A WAN (wide area network) is a network that connects LANs at distant places. The WAN uses a general telephone line, ISDN, a dedicated line, a communication satellite, or the like as a connection line.
And there is the Internet as a network that these have spread worldwide and have become huge.

[0005] On the Internet, FTP (file tra
nsfer protocol: a protocol for exchanging files between computers connected to the Internet)
There is a standard called "ano" that allows anyone to log in
There are a lot of nylon FTP servers. These F
Various free software and data for personal computers and UNIX (registered trademark) are registered in the TP server.

An HTML (hypertext markup language) capable of handling documents including images, sounds, videos, and the like for describing Web pages on the Internet.
e) FTP is also used as a standard when files and image files are registered in a Web server.

[0007] However, downloading a file using FTP can be used only with a Web browser, but when uploading a file to a server, such as updating a Web page, additional FTP software is required. In this case, the user manually starts the FTP software, accesses the FTP folder on the Web, and uploads a file or the like.

[0008]

By the way, as described above, the function of the conventional briefcase is to keep the information of the file copied to a portable recording medium such as a shared folder or FD of another host on the LAN always up-to-date. However, this function alone has a problem that information cannot be updated for a shared folder on a LAN that requires a password, a read-only disk device that is not writable, and the like.

[0009] Further, conventional FTP software cannot automatically update information of local files and files on the Web, and unless the user manually starts the FTP software to upload information as described above. Therefore, there is also a problem that file information differs between file information in the FTP folder on the Web and file information of the local host.

[0010] This causes a problem that it is troublesome and inconvenient to provide the contents of the home page with constantly updated contents. An object of the present invention is to provide a file for automatically updating the file information for all of the original file and the copied file when any of the file information of the original file and the copied file is changed in view of the above conventional situation. It is to provide a management device and its program.

[0011]

A file management apparatus according to the first aspect of the present invention stores a created file and a file copied from the file to an external apparatus connected via a communication network. A first storage for storing a created file in a predetermined folder and storing path information of the external device for storing the file in association with a file name of the file. Means, and first monitoring means for monitoring whether the file in the predetermined folder has been updated,
When the update of the file is detected by the first monitoring means, the first monitor corresponds to the file name of the file.
Second updating means for updating the file of the external device relating to the path information stored in the storage means of
Second storage means for storing the created file in the predetermined folder and storing path information of the predetermined folder in association with the file name of the file;
Second monitoring means for monitoring whether or not the file copied to the external device has been updated; and when the second monitoring means detects the update of the file, the second monitoring means corresponds to the file name of the file. A second updating of the file in the predetermined folder related to the stored path information;
And updating means.

The first storage means stores the authentication information for accessing the external device in association with the path information of the external device, for example, as set forth in claim 2, and said first update means Is configured to perform an access authentication process based on the authentication information stored in association with the path information when updating the file of the external device related to the path information.

Next, the program according to the third aspect of the present invention realizes, by a computer, a process for managing a created file and a file copied from the file to an external device connected via a communication network. A first storage function of storing the created file in a predetermined folder and storing path information of the external device that stores the file in association with the file name of the file; A first monitoring function for monitoring whether or not the file in the predetermined folder has been updated; and, when an update of the file is detected by the first monitoring function, the first monitoring function corresponds to a file name of the file. A second update function for updating the file of the external device relating to the path information stored in the first storage function; A second storage function of storing a file in the predetermined folder and storing path information of the predetermined folder in association with a file name of the file; and determining whether the file copied to the external device has been updated. A second monitoring function for monitoring whether the file is updated by the second monitoring function, and when the update of the file is detected by the second monitoring function, the predetermined folder related to the path information stored corresponding to the file name of the file. And a second update function for updating the file is realized by the computer.

The program has a function of storing authentication information for accessing the external device in association with the path information of the external device, and a program related to the path information. When the file of the external device is updated, a function of performing an access authentication process based on the authentication information stored in association with the path information is further realized by the computer.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram illustrating a configuration of a local host as a file management device and an entire system involving the local host according to an embodiment. As shown in FIG. 1, the local host 1 is connected to the LAN 2. Another host 3 as an external device is also connected to the LAN 2. LAN2
Is connected to a WAN 4, and a host 5 as an external device is also connected to the WAN 4.

The local host 1 has a plurality of “virtual WWs” of the present invention created by a user interface.
b cache folder 6 ”(hereinafter simply referred to as virtual folder 6).
Is provided). The WAN host 5 is provided with a plurality of FTP folders 7.

The user creates an arbitrary file 8 in the virtual folder 6 of the local host 1 and stores the file 8 in an arbitrary FTP folder 7 of the host 5 on the WAN 4.
Alternatively, the data can be copied to, for example, the HDD of another host 3 on the LAN 2 or to the FD 9 which is a portable recording medium.

Thereafter, the WAN copied from "file 8" (original file) on the virtual folder 6
"File 8" in FTP folder 7 of host 5 on 4
(Copy file), “file 8” (copy file) of other host 3 on LAN 2 and “file 8” of FD 9
(Copy files) can always hold the same file contents. For example, when the content of “File 8” on the LAN 2 is updated, the file “File 8” in the FTP folder 7 on the WAN 4 and the file “File 8” in the FD 9 are saved through the virtual folder 6. Updated automatically. The same applies to a shared folder requiring user authentication. Hereinafter, this will be described in detail.

FIG. 2 shows the configuration of FIG. 1 in a hierarchical structure of connections from a different viewpoint. In FIG. 2, the LAN
A plurality of hosts 3 (3-1, 3-2) as a host L1,
Host L2 is shown, and host 5 of WAN 4 is shown as host W1. A plurality of virtual folders 6 (6-1, 6-2) of the local host 1 are indicated by a virtual folder A and a virtual folder B, and a plurality of files 8 (8-1 to 8-5)
Are represented by file a, file b,..., File e, respectively. In the following description, description will be made using the names of the virtual folder A, virtual folder B, host L1, host L2, host W1, and files a to e.

As shown in FIG. 1, in the present system, first, virtual folders are created on the local host 1 as shown in the figure as a virtual folder A, a virtual folder B,. Next, in these arbitrary virtual folders A or B,
Arbitrary files are file a, file b,.
・ Created like file e. Then, arbitrary files a, b,... Or e of the files a to e in the virtual folder A or B are copied to an external device such as the host L1, L2, W1, or FD. Then, after this, the update of the file in the virtual folder (original file) and the file in the external device (copied file) are monitored,
When the original file is updated, the copy files in all the external devices are updated in accordance with the update. On the other hand, when any of the copy files in the external device is updated, the original file is updated, and the copy files of other external devices are updated.

FIG. 3A is a flowchart of a process for creating a virtual folder on the local host 1.
(b) is a diagram showing a virtual folder table set in the memory device of the local host 1 by the processing.
First, the user starts the virtual folder creation / management module of the present invention mounted on the local host 1. Then, although not particularly shown, the virtual folder creation processing is started by pressing (clicking, the same applies hereinafter) the virtual folder creation button displayed on the startup screen (step S1).

First, an arbitrary path position of a virtual folder to be created is designated (step S2). In this process, one of the hierarchically structured folders on the HDD is designated,
By calling the new folder creation module,
The path position is determined. Next, a virtual folder name is input (step S3). In this process, although not specifically shown, a new virtual folder name is input to a folder / icon name input window displayed on the hierarchy in which the path position is determined. As a result, a new virtual folder is set at the path position (step S4).

The virtual folder creation / management module stores the path information and the virtual folder name in the virtual folder table in association with each other (step S5). Thus, a virtual folder table 10 as shown in FIG. 3B is created on the memory of the local host 1. As shown in FIG. 2B, the virtual folder table 10 has row areas 11 (11-1, 11-2,...) Corresponding to the number of virtual folders.
.), And each line area 11 includes a virtual folder path information area 12-1 and a virtual folder name area 12-2. The virtual folders A and B shown in FIG. 2 are already registered in the virtual folder name area 12-2 shown in FIG.
Also, arbitrary files are created in these virtual folders.

FIG. 4 is a flowchart for explaining a file copy (copy) process performed after the above process. FIGS. 5A and 5B show an authentication table and a copy destination table created in accordance with the above-described file copy process. First, as shown in FIG. 4, when a file to be copied is designated by the user to copy the file, the file to be copied is detected (step S11).

Subsequently, it is determined whether or not the file designated as the file to be copied exists in any of the virtual folders (step S12). If the file designated as the file to be copied exists in any of the virtual folders (Y in S12), in that case, the input of the designation of the copy destination is waited, and the designation of the copy destination is input (step S13). ), And obtains the path information of the designated copy destination (step S14). This path information is, for example, “{host L1}...” If it is a copy destination in the same LAN, and a URL address of the HTTP protocol if it is a WAN or a copy destination on the Internet via the WAN. And so on.

Subsequently, it is determined whether or not authentication is required to access the above-mentioned copy destination address (step S1).
5) If authentication is necessary, a dialog to that effect is displayed to wait for the input of the copy destination authentication information, and the input of the authentication information is obtained (step S16). The obtained authentication information is registered in the authentication table 13 shown in FIG. 5A (step S17).

[0027] As shown in FIG.
Is the row area 14 (14-1, 1) corresponding to the number of copy destinations.
4-2,...), And each line area 14 includes a copy destination path information area 15-1, a user name area 15-2 which is one of authentication information, and another one of the authentication information. It consists of a certain password area 15-3. This authentication table 13
The path information of the copy destination and the authentication information for the copy destination are stored in association with each other.

Next, as shown in FIG. 4, the name of the virtual folder from which the file is copied, the name of the file to be copied, and the path information of the copy destination are stored in the copy destination table shown in FIG. 16 (step S1)
8). Then, the file specified in step S11 is copied to the copy destination specified in step S13 (step S19).

Then, it is determined whether or not a copy destination is specified in addition to the above (step S20). If the copy destination is specified (Y in S20), steps S13 to S20 are repeated. Thereby, as shown in FIG. 5B, a row record area 17 is formed in the copy destination table 16 for each virtual folder name. In the example shown in FIG. 7B, a line record area 17-1 corresponding to the virtual folder A and a line record area 17-2 corresponding to the virtual folder B are formed.

Each row record 17 includes a first hierarchical area 18-1 in which the virtual folder name is stored and a second hierarchical area 18- in which the name of the file to be copied is stored.
2 and the third hierarchy area 18 where the copy destination path information is stored
-3 are hierarchized into three layers of data area. As shown in FIG. 2, the files a, b, and c of the virtual folder A are such that the files a, b, and c are copied to the LAN host L1, and the files a and c are further copied to the WAN host W1.
1, but files d and e are not copied anywhere.

Therefore, in the copy destination table 16 shown in FIG. 5B, the second hierarchical area 18-2 of the row record area 17-1 corresponding to the virtual folder A contains the files a and b.
The row region is divided into three in correspondence with (a) and (c). Further, the row record areas 19 (19-1, 19-2, 19) of the files a, b, and c in the third hierarchical area 18-3 of the row record area 17-1 corresponding to the virtual folder A
In (-3), the line area is further divided by the number of copied external devices.

However, there is no data in the row record area 17-2 corresponding to the virtual folder B, so the second layer area 18-2 and the third layer area 18-3 of the row record area 17-2 are divided. Absent. In this way, the name of the virtual folder from which the file is copied, the name of the file to be copied, and the path information of the copy destination are stored (registered) in the copy destination table 16 in association with each other.

Incidentally, in FIG. 4, the designation of copying is all completed,
If no other copy destination is specified (N in S20), the process ends. Also, the above-described step S12
If the file to be copied is not a file in the virtual folder (N in S12), the process waits for a copy destination designation input (step S21), and based on the designation input, the copy destination designation is set to the designated copy destination. A normal copy process for copying the file is performed (step S22), and the process ends.

Subsequently, in this example, after the copy information of the file is stored in the virtual folder as described above, the monitoring of the virtual folder is performed at regular intervals. FIG. 6 is a flowchart of a process of monitoring a virtual folder at regular intervals. In the figure, first, a folder in the virtual folder table is designated (step S101). This processing is performed by starting from the virtual folder name area 12-2 of the row area 11 (11-1, 11-2,...) Corresponding to the number of virtual folders in the virtual folder table 10 shown in FIG. This is a process for sequentially extracting folder names. In the example of the virtual folder table 10 shown in FIG. 3B, the first virtual folder name "A" is designated (extracted in the work area).

Subsequently, it is determined whether or not a file exists in the virtual folder (step S102). This process is a normal file search process by a file management module known by the name of a file manager or an explorer, for example. If there is a file in the specified virtual folder (virtual folder A at first) (Y in S102), the file is specified (step S103). In this process, if there are three files a, b, and c in the virtual folder A as shown in FIG. 2, for example, the first file a is specified.

Subsequently, the update date and time added as the current attribute of the specified file a is compared with the update date and time when the file was checked in the previous file monitoring process (step S104), and the previous file monitoring process was performed. It is determined whether or not the file a has been updated after the check in (Step S105). Then, if the file a has been updated after the check in the previous file monitoring process (Y in S105), the path information of the copy destination corresponding to this file is obtained (step S106).

This processing is performed in the copy destination table 16 shown in FIG. 5B, in the row record 17-2 of the virtual folder A in the first hierarchy 18-1 and in the row a of the file a in the second hierarchy 18-2. This is a process of reading the path information of the copy destination stored in the third hierarchy 18-3 of the record 19-1.

Subsequently, it is determined whether or not authentication is required to access the copy destination path obtained by reading (step S107). This processing determines whether or not there is any copy destination path information area 15-1 in the row area 14 of the authentication table 13 shown in FIG. This is the process of determining.

If there is any path information having the same path information as the above path information, it is determined that authentication is required (Y in S107), and the authentication information corresponding to the copy destination path is obtained. (Step S108). This processing is performed in the user name area 15-2 and the password area 1 of the row area 14 where the copy destination path information area 15-1 having the path information coincident with the path information of the authentication table 13 is provided.
This is the process of reading the user name and password from 5-3.

Subsequently, the external host of the copy destination path information is accessed by the obtained user name and password authentication information (step S10).
9). Then, the copy file copied in the accessed external host is updated (step S1).
10). Thus, for example, for file a,
The file a of the LAN host L1 shown in FIG. 2 is updated first.

Subsequently, it is determined whether there is another copy destination for the same file (step S111). If there is another copy destination (Y in S111), the above-mentioned step S10 is performed.
6 to S111 are repeated. As a result, for the file a, the file a of the host W1 of the WAN shown in FIG. 2 is updated next.

If all the copy destinations for the same file have been updated and the determination in step S111 is negative (N in S111), then there is another file in the same virtual folder. It is determined whether or not it is (step S112). If there is another file, the process returns to step S103, and returns to steps S103 to S1 described above.
Repeat step 12.

Accordingly, it is monitored whether or not all the files a, b, and c in the virtual folder A shown in FIG. 2 have been updated. Be updated. In FIG. 6, it is further determined whether or not there is another virtual folder following the above (step S113). If there is another virtual folder, the process returns to step S101 and returns to step S101.
101 to S113 are repeated. As a result, if there is another virtual folder, all the files in the virtual folder are monitored to detect the presence or absence of the update. If the virtual folder is updated, the same file at all the copy destinations is updated.

Also, in the above-described determination in step S105,
If the file has not been updated after the previous check in the file monitoring process (N in S105), the process immediately proceeds to the process in step S112. Step S
If there is no file in the virtual folder (S102: N), the process immediately proceeds to step S113.

The above processing is performed when it is detected that a file in the virtual folder has been updated. However, when the file at the copy destination has been updated, the update is detected and the file in the virtual folder is updated. The same file is updated. Then, based on the file update in the virtual folder, the same file in another external device is updated as described above.

Next, a description will be given of a process of updating the same file in the virtual folder by monitoring the update of such a copy destination file at regular intervals and detecting the update. FIG. 7 is a flowchart of a process of monitoring a file at a copy destination at regular intervals and updating a file in the virtual folder based on detection of the update.

FIG. 8 is a diagram showing a configuration of a sort table created in the above processing. First, in FIG. 7, the copy destination table 16 is sorted by copy destination to create a sort table 20 shown in FIG. 8 (step S2).
01). As shown in FIG. 8, the sort table 20 includes:
Copy destination path information (here, host L1, host L2,
..)) For each row record area 21 (21-
1, 21-2,...) Are formed.

Each row record area 21 has a two-level data area. The first level area 22-1 of each row record area 21 stores copy destination path information. That is, “host L1” is stored in the first layer area 22-1 of the row record area 21-1, and the row record area 21-2
"Host L2" is stored in the first hierarchical area 22-1, and a row record area 21-3, which is not shown in FIG. −
“1” stores “host W1”.

The second hierarchy area 22-2 of each row record area 21 is divided into row areas for each file name. For example, the second hierarchy area 22-2 of the row record area 21-1 corresponding to "host L1" is the file a, b
And c corresponding to three row areas 23 (23-1, 23-
2, 23-3), and the second layer area 22-2 of the row record area 21-2 corresponding to the "host L2" has two row areas 23 (23-23) corresponding to the files a and c.
4, 23-5).

Each line area 23 is stored in the file name area 2
4 and a folder area 25, and the file name area 24 stores the name of the file copied to the copy destination, that is, any one of "file a", "file b" or "file c". 25 stores the names of virtual folders from which those files are copied.

After creating such a sort table 20, a copy destination is designated in FIG. 7 (step S202). This processing is performed in the first hierarchical area 2 of the row record area 21 in the created sort table 20.
This is a process of sequentially reading out copy destination path information of 2-1.

Then, it is determined whether or not authentication is required to access the external device on the path obtained from the copy destination path information (step S203). This processing determines whether or not there is any copy destination path information area 15-1 in the row area 14 of the authentication table 13 shown in FIG. This is the process of determining.

If there is one having path information that matches the above path information, it is determined that authentication is required (Y in S203), and the user name and password corresponding to the copy destination path are determined. Acquire authentication information (step S
204), and accesses the external device on the path based on the acquired authentication information (step S205).

Then, the name of the file copied to the copy destination path is specified (step S206). In this processing, the file name of the second hierarchy area 22-2 of the row record area 21 corresponding to the path of the accessed external device in the sort table 20 is sequentially specified to the external device host. Thus, the file information of the specified file is transferred from the external device host.

If it is determined in step S203 that the copy destination path does not require authentication (S203).
203 is N), the process immediately proceeds to the process of step S206. Following the above, the update date and time of the specified file is obtained from the transferred file information (step S).
207). Then, the obtained update date and time are compared with the update date and time of the file in the virtual folder corresponding to the specified file (step S208), and whether or not the update date and time of the file of the copy destination path is later (newer). Is determined (step S209).

If the update date and time of the file in the copy destination path is later (Y in S209), the corresponding file in the virtual folder is updated using the specified file in the copy destination path and the corresponding file is updated. The update date and time of the updated file is changed (step S210).

Subsequent to the above processing, it is determined whether or not another file exists in the copy destination path being processed (step S).
211). If it is determined in step S209 that the update date and time of the file in the copy destination path is earlier (older) (N in S209), the process immediately proceeds to step S211.

If there is another file in the copy destination path being processed (Y in S211), the above-mentioned step S20 is executed.
6, the process of steps S206 to S211 is repeated. If there is no other file in the copy destination path being processed (N in S211), in that case, it is next determined whether or not there is another copy destination path (step S21).
2).

If there is another copy destination path (S2
12 is Y), the process returns to step S202, and the processes of steps S202 to S212 are repeated. If there is no other copy destination path (N of S212), the process ends. Thus, when the copy destination file is updated, the update is detected and the same file in the virtual folder is updated. Then, based on the file update in the virtual folder, the same file in another external device is updated as described in FIG. This is repeated at regular intervals, so that both the original file and the copy destination file are always kept at the latest contents.

[0060]

As described above in detail, according to the present invention, the path information of a file copied to an external device such as a host or a portable recording medium on a WAN or a LAN is stored, and the path information of the original file is stored. The update of the copy destination file is monitored, and when an update is detected, the original file or the copy destination file that has not been updated is automatically updated based on the path information. Is always up-to-date.

Since the authentication information of the external device that requires authentication at the time of access is stored in association with the path information of the file copied to the external device, the file copied to the shared folder or the like that requires authentication is stored. Updates can be easily performed by automatic authentication, which is convenient.
