A image archiving apparatus is connected to a digital still camera and acquires the serial ID and product ID of the camera. The image archiving apparatus reads image files from the camera. If a camera folder corresponding to the connected camera has been generated, the read image files are stored in this folder. If the folder has not been generated, a new folder is generated and the read image files are stored in the generated folder. Image files are organized and stored in a folder that corresponds to the model of the camera that applies the image files to the image archiving apparatus.
