Example: Accessing files on the device

This example MIDlet shows you how to use the features of the FileConnection API (FC API) to navigate the device file system and access files. The features are demonstrated in the context of a basic image viewer MIDlet, which implements a file browser for navigating the device file system and selecting images to view on the device screen.
