Therefore, It is to be understood that equivalents and modifications are possible.

FIG. 1 is a diagram illustrating a configuration of a mobile terminal according to an embodiment of the present invention. FIG. 2 is a view illustrating an input unit and a move key of a mobile terminal according to an exemplary embodiment of the present invention. 1 and 2, a mobile terminal 100 according to an exemplary embodiment of the present invention includes an input unit 110, a move key 120, a memory 130, a controller 140, and an output unit 150 .

The input unit 110 is an input device including one or more keys 110.1, ..., 110.N, and each key 110.1, ..., 110.N has a folder to be mapped, A detailed description thereof will be given later with the description of the memory 130. [ The input unit 110 includes a first key 110.1, a second key 110.2, 1, the N-1 key 110.N-1, and the N-th key 110. N, where the first key 110.1 and the second key 110.2 are respectively assigned to the first key 110.1 and the second key 110.2, N-1 key 110.N-1 and N-th key 110.N may be implemented as keys 110.N-1 and 110.N-1, respectively, * Key 110.N, but the present invention is not limited thereto.

Meanwhile, the input unit 110 may further input key identification information and folder identification information. The user can input the key identification information and the folder identification information to store the folder information mapped to the key in the memory 130 or to update the stored folder information.

The move key 120 includes a vertical movement key 120a and a left movement key 120b. The vertical movement key 120a is for moving the cursor on the list of folders or the list of files. The left movement key 120b is for moving a cursor (E.g., the second key 110.2 and the N-th key 110.N) in the state where the first key 110. 1 is input, The function key 120a or the left / right movement key 120b may be reversed in function.

The memory 130 is a storage device in which information about a folder mapped to a key is stored. First, folders are hierarchical in structure, and all folders can have a depth (or level) from 0 to about 3-4. 3 is a diagram showing an example of a hierarchical folder structure and a folder depth. Referring to FIG. 3, it can be seen that the internal memory and the external memory have a depth of 0, and a sub-folder of a camera album, an MP3 music box, a text viewer, a voice memo, have. Other folders have a depth of 2.

FIGS. 4 and 5 are views showing examples of the keys and the folders mapped to the keys. First, referring to FIG. 4, it can be seen that a folder having the same depth (for example, a folder having a depth of 0, a folder having a depth of 1, and the like) is mapped to numeric keys (0 key and 1 key). Specifically, '0 key' is mapped to a folder having a depth of 0, and in a folder shown in FIG. 3, a folder having a depth of 0 is an internal memory and an external memory. The '1' key is mapped to a folder having a depth of 1, that is, a camera album, an MP3 music box, etc. in the case of FIG. Folders with a depth of 2 are mapped to 'Key # 2', folders that have been recently executed are mapped to '* key', and folders that are frequently executed are mapped to '# key'.

Referring to FIG. 5, it can be seen that folders having the same depth but belonging to a specific upper folder are mapped to the numeric keys (key 0, key 1, etc.). Only the folders that belong to the first folder in the top-level folder (for example, internal memory) (such as camera albums, MP3 music boxes, etc.) : External memory) (e.g., MP3) is mapped to the " third key ".

Referring again to FIG. 1, the remaining components will be described.

When receiving an input signal of a specific key from the input unit 110, the control unit 140 displays a list of folders mapped to the key through the output unit 150. For example, when the input signal of 'key 1' is received, the list of folders mapped to key 1 (eg, 1. camera album, 2. MP3 music box, 3. text viewer, 4. voice memo, MP3 ). If the folder mapped to the key is the lowest folder and no other folder with the same depth exists (e.g., MP3 music box, latest music, etc.), it is preferable to display a list of files belonging to the folder because there is one folder .

When the input signal is received from the left / right movement key 120b in this state after the list of folders is displayed, the control unit 140 compares the input key (e.g., 'No. 1 key') with the adjacent key (E.g., a folder with a depth of 0 or a folder with a depth of 2) mapped to a key (e.g., a key or a second key) on the output unit 150.

When key identification information and folder identification information are input from the input unit 110, the control unit 140 stores the key identification information and the folder identification information in the memory 130 as the folder information mapped to the key or updates the existing information.

The output unit 150 is an output device that displays a list of folders under the control of the control unit 140.

6 is a diagram illustrating a procedure of a file search method in a mobile terminal according to an embodiment of the present invention. Referring to FIG. 6, first, the user inputs a file search command to search for a file stored in the mobile terminal, such as selecting a file search menu (step S110). Then, the mobile terminal performs a file search command to display a list of arbitrary folders and / or files (step S120). 7 is an example of a screen displayed after the file search command is executed.

If the user inputs a numeric key including the first key in the state where the file search command is executed (YES in step S130), the list of folders mapped to the key input in step S130 is inquired, A list of folders is displayed (step S135). Here, the list of folders mapped to the numeric keys may be a list of folders corresponding to a certain depth. 8 is an example of a screen displayed when the first key (key # 1) of the input unit is input.

If the user inputs the (N-1) th key ('* key') (Yes in step S140), the list of recently executed folders is displayed in step S145. 9 is an example of a screen displayed when the (N-1) th key (* key) of the input unit is input. If the user inputs an Nth key ('# key') (YES in step S150), a list of frequently executed folders is displayed (step S155). 10 is an example of a screen displayed when the Nth key (# key) of the input unit is input.

If the user inputs the left / right movement key (YES in step S160) while the list of the folders is displayed through step S135, step S145, or step S155, the process proceeds to step S130 (or step S140 and step S150) And displays a list of folders that are mapped to a key (e.g., a first key) and a neighboring key (e.g., an N-th key or a second key). 11 is a diagram conceptually showing a folder to be displayed when a left and right movement key is input. For example, when a list of folders to which a first key is input and is mapped to a first key is displayed and a right direction key is input, a list of folders mapped to the second key is displayed, and when a left direction key is input A list of folders mapped to the N-th key is displayed.

When the up-and-down movement key is input (Yes in step S170) while the list of folders is displayed, the up-and-down movement between the list of folders is performed (step S175). When the user selects one of the folders and repeats this process to finally select the lowest folder, a list of files belonging to the folder is displayed (step S190).

If a numeric key is input while a list of folders is displayed (YES in step S180), one folder is selected from the list of folders and the process is repeated to finally select the lowest folder. A list of files belonging to the folder is displayed (step S190).

Then, if one of the files is selected, the selected file is executed (step S200).

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It will be understood that various modifications and changes may be made without departing from the scope of the appended claims.

According to an aspect of the present invention, in the process of searching a file stored for each folder having a hierarchical structure, since the user can easily move to folders having the same level (depth), the user can easily and quickly Can be found.

According to another aspect of the present invention, since all folders having the same depth can be viewed on one screen, even if the folder (parent folder) to which the folder belongs can be moved quickly between folders having the same depth.

According to another aspect of the present invention, since a user can access a recently executed folder or a frequently executed folder with a single keystroke, a folder or a file frequently accessed by the user can be found very easily and quickly.
