Opening .upd file

I have a Casio keyboard which uses .upd file for firmware update and I wanted to extract the tones and rhythms from it so that it can be shared among forum members.

I tried hexadecimal editor but it didn't worked.

Is there any way to open or extract files from it?

Firmware file link File size is around 110 mb

Thank you for your time.
