Abstract:
1. A digital camera that records data of a photographed picture to a removable record medium and reads picture data from the record medium, comprising: a controlling portion; an operation input portion that outputs an operation signal to the controlling portion; a buffer memory that is controlled by the controlling portion and that is read from the record medium; and a single USB controller that is controlled by the controlling portion, wherein the operation input portion selects a first USB interface or a second USB interface and selection information that corresponds to the selected USB interface is stored in the controlling portion, wherein when the controlling portion receives a transfer request from the USB controller, the controlling portion transfers data from the buffer memory to the USB controller through the selected USB interface corresponding to the selection information; and wherein when the second USB interface is selected the controlling portion does not transfer a directory structure of the record medium, wherein the control portion creates an object handle for each file transferred from the recording medium according to a file name of the file and a type of the file, a predetermined number of high order bytes of the object handle indicating types of the file, wherein a relationship among files recorded in separate folders in the record medium is determined independent of a directory structure, and wherein when the relationship among the files is determined, an associated virtual folder is generated for storing related files, an object handle of the associated virtual folder being determined by a combination of object handles of the related files and a hexadecimal notation, the object handle indicating a type of a sub file included in the associated virtual folder.
