As such, the control unit 12 enters an end button for ending a specific function while performing a specific function (voice call, menu setting, etc.) of the mobile communication terminal, or waits after a predetermined time without any key button manipulation. The screen can be displayed.

When a search word for a file search is input to the input window 16 on the idle screen, the controller 12 makes a file search request to the sharing server 41 (steps S11 'to S16').

The sharing server 41 which has received the file search request from the second mobile communication terminal 10_2 searches for the file list stored in the internal database (step S17 ').

At this time, if the information about the file name is not stored separately in the database or the like, search the directory (or folder) by using the file system, check whether there is a file corresponding to the requested search word, and check the file list in real time. You can also write

In this case, when searching for a file name corresponding to the requested search word, the sharing server 41 may find only a file list having the same name as the requested search word, or having a name including the requested search word, depending on the setting. You can also find a list of all your files.

If there is no file list corresponding to the search term requested from the second mobile communication terminal 10_2 as a result of the search (step S18), the sharing server 41 transmits a message that there is no search result (step S19).

Subsequently, the sharing server 41 periodically searches the file list to find a file list corresponding to the search term requested from the second mobile communication terminal 10_2 (step S21). This is because a file having a name corresponding to a search word requested from the second mobile communication terminal 10_2 may be newly uploaded from the first mobile communication terminal 10_1.

Alternatively, the sharing server 41 may set the search word requested from the second mobile communication terminal 10_2 and determine whether the file corresponds to the set search word every time the file is uploaded from the first mobile communication terminal 10_1. have.
