Management of files stored on a digital camera includes a user interface for a windowing application for viewing system objects in a first area for displaying a hierarchical tree of system objects, a second area for displaying a thumbnail image corresponding to a system object selected in the first area, a third area adjacent to the second area for displaying a sound icon indicating that a sound file is associated with the displayed thumbnail image, and a fourth area which surrounds the second area and the third area. An item may be dragged to an icon representing a storage device in order to copy the item to the storage device.
