<Operation of file exchange system>
The operation of transmitting a file from one of the mobile devices 3-1 and 3-2 in FIG. 1 to the other will be described with reference to FIG. 7. In FIG. 7, the side that transmits the file is the mobile device on the transmitting side, and the side that receives the file is the mobile device on the receiving side. It is needless to say that the mobile devices 3-1 and 3-2 have the same configuration, and both can be the transmission-side mobile device and the reception-side mobile device. Further, as a premise of this operation, it is assumed that an application for receiving an online storage service is installed in at least the mobile device on the transmission side, and a storage area is allocated to the online storage area of the file management server 2. ..

First, when the user activates an application for receiving the online storage service from the operation unit 32 of the transmitting side mobile device, the transmitting side mobile device transmits a connection request signal to the file management server 2 (step S1). Here, when the application is activated, the login screen is displayed on the display unit 33, and the connection request signal is transmitted in response to the user inputting the ID and the password.

The file management server 2 starts the flow in response to the reception of the connection request signal, and from the folder information table (FIG. 4) stored in the online storage area of the user of the transmitting mobile device, the folder ID of the folder information, The folder name and the folder URL are read out and transmitted to the transmitting side mobile device (step S21). When the number of folders is large, the file information table (FIG. 5) is referred to based on the folder URL, and the files are transmitted in order from the folder in which the file with the newest file update date and time is stored.

The transmitting mobile device receives the folder information, holds it in the RAM in the control unit 38, and displays the folder name on the display unit 33 (step S2). If there are multiple folders, they are displayed as a list of folder names. When the user uses the operation unit 32 to specify (select) a desired folder name from among the one or more folder names displayed on the display unit 33 (step S3), the transmitting-side mobile device displays the file A file information request signal for requesting file information of a file in the folder specified by the specified folder name is transmitted to the management server 2 (step S4). This file information request signal includes the folder URL of the folder specified by the specified folder name.

The file management server 2 receives the file information request signal (step S22), and based on the folder URL included in the signal, the file information stored in the file information management table (FIG. 5) on the online storage. Is read and transmitted to the mobile device on the transmitting side (step S23).

The transmitting mobile device receives the file information, saves it in the dedicated storage area of the storage unit 34, and displays the file name and update date and time, which are bibliographic items, on the display unit 33 (step S5). Next, it is determined whether or not the thumbnail of each file is stored in the dedicated storage area of the storage unit 34 (step S6), and if stored (S6: YES), the thumbnail is displayed on the display unit 33 ( Step S9). At this time, the display unit 33 displays the text indicating the bibliographic items of each file and the thumbnail of each file side by side.

On the other hand, if not stored (S6: NO), a thumbnail request signal is transmitted to the file management server 2 (step S7). This thumbnail request signal includes the thumbnail URL. The file management server 2 receives the thumbnail request signal (step S24), reads the thumbnail on the online storage based on the thumbnail URL included in the signal, and transmits the thumbnail to the transmitting mobile device (step S25). The transmitting mobile device receives the thumbnail transmitted from the file management server 2, stores the thumbnail in the dedicated storage area of the storage unit 34 (step S8), and then displays the thumbnail on the display unit 33 (step S9).

Here, the determination in S6, that is, whether or not the thumbnail of the file is stored in the storage unit 34 is performed as follows. When the thumbnail and the file have been downloaded from the online storage in the past, the control unit 38 stores the necessary information in the file management table shown in FIG. 6, so the control unit 38 determines by referring to the management table.

An example of the screen displayed on the display unit 33 in step S9 is shown in FIG. As shown in the figure, in the image display area 102 in the screen 101, thumbnails of three files and texts 104 of bibliographic items of the respective files are displayed side by side. That is, a list of thumbnails and a list of bibliographic items of the file are displayed. Below the image display area 102, a “view” button 105 and an “exchange” button 106 are displayed. Although not shown, a cursor movement button for designating (selecting) a file is also displayed by placing the cursor on the thumbnail 103 and the text 104 of the bibliographic item.

Next, when the user specifies (selects) a file by moving the cursor to a desired thumbnail using the operation unit 32 and presses the “View” button 105 or the “Exchange” button 106 (step S10), the control unit 38 refers to the file management table (FIG. 6) and determines whether the specified file is stored in the dedicated storage area of the storage unit 34 (step S11). If the result of determination is that the file is stored (S11: YES), the file is displayed on the display unit 33 (step S14).

On the other hand, as a result of the determination, when the file is not stored (S11: NO), a file request signal is transmitted to the file management server 2 (step S12). The file request signal includes the file URL. The file management server 2 receives the file request signal (step S26), reads the file on the online storage based on the file URL included in the signal, and transmits the file to the transmission-side mobile device (step S27). The mobile device on the transmission side receives the file transmitted from the file management server 2, stores it in the dedicated storage area of the storage unit 34 (step S13), and then displays it on the display unit 33 (step S14).

If the instruction in step S10 is "view", the process ends here. On the other hand, in the case of “exchange”, after establishing communication with the receiving-side mobile device (step S15), the file is transmitted to the receiving-side mobile device (step S16).

After establishing communication with the transmitting mobile device (step S31), the receiving mobile device receives the file transmitted from the transmitting mobile device, saves the file in the dedicated storage area of the storage unit 34, and displays the file on the display unit. It is displayed on 33 (step S32).

As described above, according to the file exchange system of the present embodiment, the thumbnails and bibliographic items designated by the user are selected from the list of thumbnails and bibliographic items displayed on the display unit 33 of the transmitting mobile device. It is determined whether or not the file is stored in the dedicated storage area of the storage unit 34 in the device, and if it is stored, it is read from the storage unit 34, transmitted to the receiving side mobile device, and not stored. Is downloaded from the file management server 2 and transmitted to the receiving mobile device, the transmitting mobile device user needs to know whether the file to be transmitted is in the transmitting mobile device or on the file managing server 2. It is possible to send a file by a common operation regardless of where the file exists.

The following modifications (1) to (8) are possible with respect to the embodiment of the present invention.
(1) In S10, the order of the file designation and the instruction of "view" or "exchange" is reversed.
(2) When the "view" is instructed in S10 and the file displayed on the display unit 33 is exchanged in S14, "exchange" is instructed.
(3) When establishing communication in S15, a mobile device existing within a communicable range is searched for, and communication is established with the discovered mobile device.
(4) When establishing the communication in S15, the address book previously stored in the storage section 34 is displayed on the display section 33, and the communication is established for the mobile device having the address selected by the user from the address book. ..
(5) The mobile device on the transmission side establishes communication with the mobile device on the reception side at an arbitrary timing from after S1 to before S14.
(6) After S32, the receiving mobile device uploads the received file to the file management server 2. A thumbnail of the received file may be created and stored in the storage unit 34. The file management server 2 creates a thumbnail of the file uploaded by the receiving-side mobile device, stores the thumbnail in the storage unit 24, and transmits the thumbnail to the receiving-side mobile device. When the mobile device on the reception side creates a thumbnail of the file received from the mobile device on the transmission side and stores the thumbnail in the storage unit 34, the mobile device on the reception side rewrites the thumbnail with a more precise thumbnail received from the file management server 2.
(7) The determination results of S6 and S11 are displayed on the display unit 33.
