- a removable medium such as a memory card
- the mobile terminal 10 detects that the removable medium 100 has been attached to the main body of the mobile terminal 10 and, after the detection, detects the media access means 11 for accessing data in the removable medium 100, and A directory recorded on the removable medium 100, a directory for acquiring file information, a file information acquiring means 12, a directory for displaying a directory file list based on the directory 'file information, a file list display content creating means 13 Directory information acquired from the removable medium 100.
- there is a directory information matching judgment means for judging whether or not there is a directory name which is acquired in advance and matches the directory name of the list information. 14, list for storing list information And a broadcast holding means 15.
- the media access unit 11 When detecting that the removable medium 100 is attached to the main body of the portable terminal 10, the media access unit 11 reads the data recorded on the removable medium 100.
- file management is performed in a hierarchical structure, so that the removable medium 100 also has files recorded in a hierarchical structure in accordance with the hierarchical structure.
- the directory 'file information acquisition means 12 acquires directory' file information including directory name information recorded on the removable medium 100.
- the directory 'file list display content creating means 13 performs display processing of a directory' file list (so-called directory structure diagram) based on the acquired directory 'file information. At this time, the display content is appropriately changed based on the determination result of the list information match determination unit 14 described later. A method of changing the display content will be described later in detail. Furthermore, this The directory / file list display content creation means 13 detects input from the user interface 18 and determines which directory or file in the displayed list is selected.
- the list information is a table of directory names of specific directories conforming to application standards, and is stored in the list information holding unit 15 in advance. This list information may also store information related to the application corresponding to the specific directory.
- the portable terminal 10 is a specific directory associated with a unique application (or a unique medium, which will be described later) of each directory of data recorded on the attached medium. Whether or not the file is in the directory can be determined based on the determination.
- the list information may be obtained from the attached removable medium 100 and stored in the list information holding unit 15.
- the list information match determination means 14 determines whether or not the directory name of the acquired directory 'file information has a match with the directory name in the list information. It is determined whether or not the application corresponding to the specific directory is installed. If the corresponding application is installed, launch the application and set the contents included in the directory to a state where it can be executed by the corresponding application. On the other hand, when the corresponding application is not installed, the file operation in the directory is restricted according to the setting described later.
- the mobile terminal 10 includes an application 16 (16a, 16b, etc.) corresponding to the content, a display unit 17 for displaying a list of directories and files and various displays, and various types of information from the user to the mobile terminal 10. It has a user interface 18 that accepts input.
- FIG. 2 is a flowchart showing a procedure for processing directory / file information in the portable terminal according to the embodiment of the present invention.
- the directory 'file list display content creating means 13 executes the directory based on the directory' file information obtained from the removable medium 100 attached to the mobile terminal 10 '.
- 'Create a file list and perform list display processing step S11).
- FIG. 3 is a flowchart illustrating an example of a processing procedure for displaying a directory file list.
- the directory / file list display content creation means 13 acquires the directory 'file information from the directory' file information acquisition means 12 (step S30), and stores the directory name in the acquired directory 'file information and the list information holding means.
- the list information match determination means 14 determines whether or not there is a match with the directory name of the list information stored in the list information 15 (step S31). If there is a directory name that matches the list information (that is, a specific directory conforming to the application standard), the list information match determination unit 14 further determines whether or not the corresponding application is installed in the mobile terminal 10.
- the directory name is displayed in a different color (for example, if the corresponding application is mounted on the mobile terminal 10). Perform processing to display the list in red (for example, red that prohibits file operations). For directories and files other than the directory name that matches the list information, the list is displayed as it is (step S32). On the other hand, if the directory names do not match in step S31, the list is displayed as it is (step S33).
- a specific directory in which a file can be operated through an application a specific directory in which an application is not installed and file operation is not permitted, and a file operation can be freely performed. Since other directories that can be used are displayed separately, it is possible to prevent improper file operations that damage the integrity of data in a specific directory. Note that the display difference is not limited to colors, and any display such as font size and highlighted display can be used as long as the directory can be easily distinguished. Also, by displaying the icon of the corresponding application together, the user can easily recognize that the directory is a specific directory.
- FIG. 4 is a flowchart showing another example of a processing procedure for displaying a directory'file list.
- the directory 'file list display content creation means 13 acquires the directory' file information from the directory 'file information acquisition means 12 (step S40), and the directory name in the acquired directory' file information and the list information holding means 15
- the list information match determination unit 14 determines whether or not there is a match with the directory name of the stored list information (step S41). If there is a directory name that matches the list information (that is, a specific directory conforming to the application standard), the list information match determination means 14 It is determined whether or not the corresponding application is installed, and if it is installed, if it is installed, the directory name is deleted from the list, and the corresponding application is installed in the mobile terminal 10. Holds the directory name in a list (step S42), and displays a list of directory 'file information (step S43). On the other hand, if the directory names do not match in step S31, the list is displayed as it is (step S43).
- the directory 'The file list display content creating means 13 determines whether the selected item is a directory or a file (step S13).
- the directory 'file list display content creation means 13 causes the list information match determination means 14 to determine whether or not the selected directory matches a specific directory of the list information (step S14). If the selected directory is a specific directory conforming to the application standard, it is further determined whether or not the application corresponding to the specific directory is installed in the portable terminal 10 (step S15). If the corresponding application is installed, the list information match determination means 14 starts the application 16 (step S16). Since the file can be operated through the corresponding application, for example, even if the content file in the directory is deleted in this state, the application updates the management file, etc. There will be no data inconsistency within. When the processing of the file is completed (step S17), the list information match determination means 14 ends the application (step S18).
- the directory / file list display content creation unit 13 controls the editing of the directory such as deletion of a file. (Step SI 9).
- FIG. 5 is a flowchart illustrating an example of a processing procedure of directory editing control.
- the file list display content creation means 13 displays on the display means 17 that a directory that cannot be edited has been selected (step S50). As a result of this display process, a list of files in the directory in the selected directory is not displayed, so that the user cannot access file operations in the directory, and an improper integrity of data in the specific directory is lost. File operations can be prevented.
- FIG. 6 is a flowchart showing another example of the processing procedure of directory editing control.
- the directory 'file list display content creating means 13 displays on the display means 17 that a directory that cannot be edited has been selected (step S60), and displays a list in the specific directory selected thereon (step S60). S61). However, it is set so that the operation cannot be performed even if the file or directory is selected from the list.
- step S21 directory / file list display content creation means 13 determines whether or not an application corresponding to the extension of the file is installed in mobile terminal 10. (Step S21). If the corresponding application is installed, the application is started (Step S22), the file is processed (Step S23), and the application is terminated (Step S24). On the other hand, when the application is not installed, a message that there is no corresponding application is displayed (step S25), and the process is stopped. Note that the procedure from step S21 to step S25 is the same as the conventional processing procedure for starting an associated appropriate application based on the file extension.
- the list information includes up to the type of media, and it is possible to distinguish whether file operations should be restricted for the directory with the directory name according to the type of media attached to the mobile terminal. It is even more preferable. In this way, for example, a file in a specific directory conforming to a predetermined media-specific application standard can be accessed only through a corresponding application only when recorded on the predetermined medium, or , It is possible to perform a process for restricting access.
- the information device of the present invention permits inappropriate file operations by permitting access to files in a specific directory only when an application corresponding to the specific directory conforming to the application standard is installed. Thus, it is possible to prevent the integrity of data in a specific directory from being impaired, and it is useful as an information device to which a storage medium can be attached and detached.
