How to include .hex file on arduino?

I had include Little Duck.hex file in arduino.

#include "Little Duck.hex"

But it error

MultiWiiV1_7.cpp:3:27: error: Little Duck.hex: No such file or directory
I want to know how to include .hex file for arduino?

What do you wanna do? Including a .hex file does not make sense as the compiler does not know what to do with such a file. Usually .hex files are compiled binaries ready for being transferred to the MCU.
