Here, a process for transmitting a file having the file structure shown in FIG. 6, that is, a transmission file containing a document file, a table file, and a graph file, from workstation 1 to workstation 5 will be described.

At the sending workstation 1, as shown in FIG.
00), the CP023 loads the file corresponding to the specified file name from the disk device 15 into the real memory 18, acquires file information regarding the file including the file name and file structure (step 1
01), calculate the file size of the corresponding file based on the obtained file information (step 102)
.

Having calculated the file size, the CPU 23 calls the destination based on the telephone number indicating the destination set in step 100 above (step 103), and then, before sending the file itself, sends a message including the file size. After transmitting the file information (step 104), transmission of the file itself is started (step 105).

The above file information and file body are stored in the real memory 18
, communication control unit 21, communication boat 22, RS232C
The signal is transmitted to a telephone line 4 via a cable 2 and a modem 3, and then input to a workstation 5 on the receiving side via a modem 7 and an RS232C cable 6.

Note that sending file information including the file size before sending the file itself is to inform the receiving side of the file size and to send the entire file before receiving all the files to be received. This is to make it possible to calculate the file size.

By the way, if the user issues a transmission status display instruction by selecting a menu or the like during file transmission (step 106), the CPU 23 obtains the current transmission information (step 107) and displays the instruction. Calculating the amount of files to be sent at the time (step 108)
, the calculation result is sent to the display control unit 17, and the transmission status as shown in FIG. 7 is displayed on the display device 17 (step 109).

Note that, as shown in FIG. 7, the transmission information includes the file name, the total number of items, the name of the file being transmitted, and the amount of transmission.

On the other hand, in the workstation 5 on the receiving side, as shown in FIG. (Step 2o1), after receiving the file information,
The reception of the file body is started (step 202).

The received file information and file body are stored in the real memory 18 via the communication boat 22 and the communication control unit 21.

By the way, if the user issues a reception status display instruction through menu selection or the like while receiving a file (step 203), the CPU 23 acquires the current reception information (step 2o4) and displays the instruction. Calculating the amount of files received at the time (step 205)
, the calculation result is sent to the display control unit 17, and the reception status as shown in FIG. 8 is displayed on the display device 17 (step 206).

Note that, as shown in FIG. 8, the reception information includes the file name, the total number of items, the name of the file being received, and the amount of received traffic.

Next, the file transfer processing operation when transmitting a file to a specific party when the transmitted file requires security protection will be explained based on the flowcharts of FIGS. 9 and 10.

Here, it is assumed that a file is transmitted from workstation 1 on the sending side to workstation 5 on the receiving side.

At the workstation 1 on the sending side, as shown in FIG. 9, when the user specifies the destination user name, file name, and telephone number indicating the destination, and issues a file transmission instruction (step 300), the CPU 23 loads the file corresponding to the specified file name from the disk device 15 into the real memory 18, then calls the other party based on the telephone number indicating the specified sending party (step 301), and further, Send file transmission information including the destination user name and file name (step 302)
.

After completing step 302, the CP023 acquires transmission permission information from the receiving side that has received the file transmission information (step 303), and determines whether or not this transmission permission information indicates transmission permission (step 303). 304), if the result of this judgment is that transmission is permitted, the file body is transmitted (step 305); on the other hand, if transmission is not permitted, an error message to that effect is output (step 306). .

By the way, during the file transmission in step 3051, it is possible to display the file transmission status to a specific destination user by performing the same process as the file transmission process shown in FIG. 4 above. Can be done. Therefore,
The user can confirm what kind of file has been sent to a specific destination user and how long the file has been sent.

On the other hand, in the workstation 5 on the receiving side, as shown in FIG. received (step 401), and then checks the destination user name included in the file information (step 402).
, 111 determines whether or not the downstream user name is a user registered in the workstation 5 (step 403), and if the result of this determination is that the user is not registered, transmission is prohibited as transmission permission information. The sender is notified (step 404), and if the user is registered, the sender is notified (step 404).
3. After notifying the sender ffll1 of transmission permission as permission information (step 405), the file body is received from the sending side that has received the transmission permission information indicating transmission permission (step 406).

For example, as shown in FIG. 11, when the sender requests the destination user X to send a file, the receiver's workstation sends the user A1B. If C is registered as a user and user X is unregistered,
The receiving side notifies the sending side that transmission is not possible as transmission permission information.

Furthermore, as shown in Fig. 12, when the sending side makes a file transmission request to the subordinate user X, if users X, Y, and Z are registered on the receiving side's workstation, then The receiving side notifies the transmitting side that transmission 1i'1 is possible as transmission 6'r possible information.

Note that in step 406 above, the file can be received by not only the destination user designated by the sender and registered as a user, but also all users registered in the workstation 2. be.

Now, after completing step 404 or step 406, the CPU 23 determines whether or not the other user has been authenticated when the user issues an instruction to obtain the received file (step 407). ++Decline (step 408), and if the password etc. match and the user is authenticated, the file can be obtained (step 40).
9) On the other hand, if the user is not authenticated, an error message indicating this is output (step 410).

Note that if you are not a registered user, you will not be able to retrieve the file, and even if you are registered, you will not be able to retrieve the file if the user is not authenticated. . Therefore, only a specific destination user designated by the sending side can receive the file and can further acquire the file.

For example, as shown in FIG. 12, each registered user XSYSZ can receive a file from the sender, and only authenticated user X can obtain the received file and open the file. can do. However, since user YSZ was not authenticated, he cannot obtain the received file.

By the way, while the file is being received in step 406, the registered user can display the file reception status by performing the same process as the file reception process shown in FIG. can do.

Therefore, a specific destination user can confirm what kind of file is currently being received and how much of the file has been received.

In the above embodiment, a telephone line is used as the communication line, but the present invention is not limited to this and can be applied to any communication line. For example, it may be a local area network such as Ethernet.

According to the above embodiment, sending (or receiving) a file
When an instruction is given to display the transmittal letter B (or receipt!!3) of the file, the current transmitting status (or receiving status) of the file can be displayed on the display means.

〔Effect of the invention〕

As explained above, according to the present invention, when an instruction is given to display the file processing status during file transmission/reception, the current file processing status is recognized and the recognition result is displayed on the display means. Therefore, you can check the file sending/receiving status while the file is being sent/received.
