  Next, a data processing operation in the mobile terminal device 100 according to an embodiment of the present invention will be described with reference to the flowchart in FIG. FIG. 5 shows a flowchart of a data processing program executed in the control unit 20.

  As a premise, the folder configuration of the storage unit 13 of the mobile terminal device 100 and the folder configuration of the storage device 113 of another device (PC 151) to be connected are as shown in FIG. It is assumed that the music data file shown in FIG. 6 is stored in each folder. More specifically, the storage unit 13 is provided with the transmission folder 131, the deletion folder 132, and the reception folder 133 as described above. The storage device 113 of the PC 151 includes the transmission folder 141, the ripping folder 142, and the like. A reception folder 143 is provided.

  Furthermore, a music data file to be transmitted is stored in the transmission folder 131 of the storage unit 13 of the portable terminal device 100, and a music data file to be deleted is stored in the deletion folder 132 by a user operation. It shall be. Furthermore, it is assumed that the music data file to be transferred to the mobile terminal device 100 by the user is already stored in the transmission folder 141 of the storage device 113 of the PC 151. Further, music data files having the same file name are assumed to be the same music data file.

  As shown in FIG. 5, first, in step 201, the process waits until the connection between the mobile terminal device 100 and the PC 151 is established. These connections are connected by the USB cable 110, and data communication is possible. When the connection with the PC 151 is established, this determination is affirmed and the routine proceeds to step 203. In step 203, the control unit 20 determines whether or not a music data file is stored in the deletion folder 132 of the storage unit 13. If this determination is affirmed, the process proceeds to step 205, and if not, the process proceeds to step 209. As shown in FIG. 6, since File_004, File_007, and File_008 are stored in the deletion folder 132, the determination is affirmed and the process proceeds to Step 205.

  In step 205, the control unit 20 determines whether the same file as the music data file stored in the deletion folder 132 exists in the storage device 113 of another device. More specifically, the control unit 20 refers to the music data file stored in the storage device 113 via the communication unit 12 and determines whether or not the same file is stored. If this determination is affirmed, the process proceeds to step 207, and if not, the process proceeds to step 209.

  For example, as illustrated in FIG. 7A, File_004, File_007, and File_008 are stored in the deletion folder 132 of the storage unit 13, and File_004 and File_007 are stored in the ripping folder 142 of the storage device 113 of the PC 151. Assume that it is stored. In this case, since File_004 and File_007 exist as the same music data file in the storage device 113, the determination in step 205 is affirmed and the process proceeds to step 207.

  In step 207, the control unit 20 deletes the music data file in the deletion folder 132. As a result, for example, as shown in FIG. 7B, the music data files, File_004 and File_007 stored in the deletion folder 132 of the storage unit 13 are deleted. File_008 remains without being deleted because there is no corresponding file. After step 207 is completed, the process proceeds to step 209.

  In step 209, which is executed after the determination is denied in step 203, after the determination is denied in step 205, or after step 207 is executed, the control unit 20 stores the music data file in the transmission folder 131. It is determined whether or not. If this determination is affirmed, the process proceeds to step 211, and if not, the process proceeds to step 213. For example, as shown in FIG. 8A, if the music data files File_001, File_002, and File_003 are stored in the transmission folder 131 of the storage unit 13, the determination is affirmed and the process proceeds to step 211.

  In step 211, the control unit 20 transmits the music data file in the transmission folder 131 to the PC 151 via the communication unit 12. Thereby, for example, as shown in FIG. 8B, the music data files File_001, File_002, and File_003 stored in the transmission folder 131 of the storage unit 13 are transferred to the storage device 113 of the PC 151 and the reception folder 143 thereof. Stored in After step 211, the process proceeds to step 213.

  In step 213 which is executed after step 211 is executed after the determination in step 209 is denied, the control unit 20 determines whether or not the music data file is stored in the transmission folder 141 of the storage device 113 of the PC 151. judge. If this determination is affirmed, the process proceeds to step 215. If the determination is negative, the process ends. For example, as shown in FIG. 9A, when the music data files File_009, File_010, and File_011 are stored in the transmission folder 141 of the storage device 113 of the PC 151, the determination is affirmed and the process proceeds to step 215. .

  In step 215, the control unit 20 transmits a file transfer request to the PC 151 via the communication unit 12. In response to this request, the PC 151 transmits the music data file in the transmission folder 141 to the mobile terminal device 100. The control unit 20 stores the music data file received via the communication unit 12 in the reception folder 133. For example, as shown in FIG. 9B, the music data files File_009, File_010, and File_011 stored in the transmission folder 141 of the storage device 113 of the PC 151 are stored in the reception folder 133 of the storage unit 13. After step 215 ends, the process ends.

  As described above in detail, according to the present embodiment, each of a plurality of music data files can be stored in the storage unit 13 in a folder associated with data processing such as transmission, deletion, and reception. ing. The user can store individual music data files in any folder when he / she thinks.

  When the communication unit 12 establishes a communication connection with another device, the control unit 20 executes data processing associated with each folder. In this way, the user selects a song that he or she wants to add or delete when he / she can take time, and then, when the user is in communication connection with the PC 151 or the like, Data processing related to the music data file can be performed collectively. That is, the user can specify data processing to be performed on the music data file at any time for the music data file, and the data processing can be performed in a batch with the data processing enabled. Can be done. This makes it easy to replace music data files, which has been very troublesome in the past, reducing the burden of operation and reducing the burden on the user when managing and editing data files. Can be reduced.
