2 is an exemplary view for explaining a file restoration method of a portable terminal capable of mounting an external memory card according to an embodiment of the present invention.

Referring to FIG. 2, the controller 17 reads the schedule data of a specific file selected by the user from among the files of the external memory card mounted in the terminal, stores the temporary data in the memory (), and selects the copied data. After creating a copy log file for a specific file, update the copy file in real time.

At this time, the controller 17 determines whether a normal situation such as a call incoming, an alarm or a short message is received, and determines whether an abnormal situation such as battery detachment or power off occurs.

As a result, when the normal or abnormal situation occurs, a copy progress rate is displayed as an icon on one side of the display unit 18 while performing a series of operations corresponding to the generated situation as shown in FIG.

When the user inputs a specific key to know the copy progress in more detail, the control unit 17 displays the file name (aa.mp3), the progress rate (62%), and today's date as shown in FIG. 2005.6.10). At this time, the display unit 18 asks whether to continue copying the file (aa.mp3) (Continue / Delete? (Y / N)).

Then, the user selects whether or not to proceed with the copy, and the control unit 17 continuously updates the log file and finishes copying the temporary file according to whether the copy is in progress.

Thereafter, the file name of the temporary file is changed to the file name stored in the log file, and the log file is deleted after storing the file as a normal file in the memory 16.

3 is a flowchart illustrating a file restoration method of a portable terminal capable of mounting an external memory card according to an embodiment of the present invention. The portable terminal starts on the premise that an external memory card is installed.

Referring to FIG. 3, in step 301, the controller 17 determines whether to execute the copy mode in order to copy a specific file stored in an external memory card. Start copying files.

In step 305, the controller 17 generates a copy log file having a file name of the file to be copied and data size information of the file.

In step 307, the controller 17 reads a predetermined amount of data from the original file of the external memory card.

In operation 309, the controller 17 stores a predetermined amount of data read from the external memory card in the memory 16. At this time, the file stored in the memory 16 is a temporary file and has a unique file name using a current date or the like. That is, for example, if the current date is November 3, 2005, the temporary file name is '20051103xxxx.temp'. Here, xxxx is information which may have a unique file name and may be a current time (xx hour xx minutes).

In step 311, the controller 17 determines whether it is the last data of the original file stored in the memory 16 through steps 307 to 309. If it is the last data, the controller 17 proceeds to step 313, and if not the last data, the controller 17 proceeds to step 315. .

In step 313, the controller 17 changes the file name according to the information of the copy log file and stores the temporary file name.

However, in step 315, the controller 17 determines whether a normal situation such as an incoming call, an alarm or a short message is received, or an abnormal situation such as battery detachment or power off occurs.

If a normal situation or abnormal situation occurs as a result of the determination, when the normal situation occurs in step 317, the control unit 17 processes the normal situation (call reception processing, alarm processing, short message receiving processing, etc.), The copy progress rate is displayed as an icon on one side of the display unit 18.

However, if an abnormal situation occurs, in step 319, the control unit 17 detects when the power is turned off and then reboots, and then proceeds to step 321 to determine whether to continue copying the corresponding file interrupted during copying. Ask.

Accordingly, if the user wants to continue copying the corresponding file interrupted during copying, the controller 17 continuously copies the original file interrupted during copying to the last data in step 323, and then proceeds to step 325. Change the file name according to the log file information and save it. Thereafter, the controller 17 deletes the copy log file.

However, if you do not want to continue copying the file that was previously interrupted during copying, the controller 17 deletes the temporary file and copy log file previously interrupted during copying.

On the other hand, if it is determined in step 315 that the normal situation such as call reception, alarm or short message reception or abnormal situation such as battery detachment and power off does not occur, the process returns to step 307.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention.
