ExBox for

From ExBox:

ExBox is a PalmOS application that enables a infrared (IR)-capable PalmOS device (see compatible device lists below) to exchange arbitrary files between Palm PDA and other IR-capable devices.

ExBox allows you to register arbitray file extensions with PalmOS (V3.0+) running on your Palm PDA. When a file is beamed from another IR-capable device (most laptop computers, Windows CE PDA, Desktop computer with a IR adaptor/dongle, etc) and received by the Palm PDA, it will notify ExBox. ExBox then stores the file and keeps the information in its databse. You may later beam the file to another IR-capable computer, or to another Palm PDA with or without ExBox.
