DFU file from command prom

Hi

I would like to create the DFU file once I compile the whole program, in a way the the file *.dfu is already ready to be updated with the bootloader. 

I already know that there is the program "Dfu file manager", does anyone know how to use it from command prompt in a way that I can do a script file to execute the conversion directly without opening it?

Does anyone can give me an hint?

Thank you in advance
