In this example, the case where the removable medium is connected to the image processing apparatus 100 via the USB reader / writer 180 will be described, but the same applies to the case where the removable medium is directly connected to the USB connector 170.

  First, it is determined whether or not the removable medium is connected to the USB connector 170 via the USB reader / writer 180 (step S901). If the removable medium is not connected to the USB connector 170 via the USB reader / writer 180 (step S901), the connection of the removable medium is monitored (step S901).

  When the removable medium is connected to the USB connector 170 via the USB reader / writer 180 (step S901), a predetermined recording position (root) of the removable medium connected to the USB connector 170 via the USB reader / writer 180 is obtained. Information recorded at a recording position immediately below the directory is read (step S902). For example, when the removable medium A (300) is connected to the USB reader / writer 180, the media information file 320 recorded in the removable medium A (300) is read. Then, the content of the read media information file 320 is stored in the storage unit 120.

That is, a file corresponding to the file path of the removable medium connected to the USB reader / writer 180 is read, and it is determined whether or not this file is an icon file (step S903). For example, it is determined whether or not the file corresponding to the read file path is “icon file.jpg”.

  If an icon file exists in the file path described in the read information (step S903), this icon file is read (step S904). For example, the icon file 350 shown in FIG. 4 is read. On the other hand, if no icon file exists in the file path described in the read information (step S903), the default icon image data stored in the storage unit 120 is read (step S904).

  Subsequently, an icon is drawn based on the icon image data recorded in the read icon file (step S906). For example, the icon 356 is drawn based on the icon image data 355 recorded in the icon file 350. If no icon file exists (step S903), a default icon is drawn based on the default icon image data read from the storage unit 120 (step S906).
