If the same file as the copy target file exists in the selected folder of the HDD 151, the main control unit 160, as shown in FIG. 10, selects whether to copy the file or not to copy the file before the skip processing. The processing 750 is displayed so as to overlap the predetermined portion of the HDD play list screen 600. The main controller 160 determines whether to copy a file in response to a user's file copy selection signal.

When the file copying operation is completed (S1120), the main controller 160 terminates the file copying operation. If the file copying operation is not completed, the main control unit 160 switches to step S1090 to continue the file copying operation.

Meanwhile, if each selection signal is not received in steps S1020, S1040 and S1080, the idle state is maintained as in steps S1025, S1045 and S1085, respectively.

While the above has been shown and described with respect to preferred embodiments of the present invention, the present invention is not limited to the specific embodiments described above, it is usually in the technical field to which the invention belongs without departing from the spirit of the invention claimed in the claims. Various modifications can be made by those skilled in the art, and these modifications should not be individually understood from the technical spirit or the prospect of the present invention.

According to the video and audio recording / reproducing apparatus and the file copying method according to the present invention, when copying video and audio files recorded on an optical recording medium such as a CD or DVD to an HDD, a file having the same name as the copy target file selected on the HDD If present, automatic skip processing is possible. Also, before auto skip processing, a message to select whether or not to copy the file can be displayed to reconfirm whether or not the file is copied. This enables automatic skip processing for the same file at the time of file copying, thereby reducing the time required for copying.
