Guide on adding a new model, animation, and creature to HoMMV

Hello everyone, and a huge thank you for the guide on transferring models to HMM5, special thanks to zahar0z for the individual consultation and tips.
My first creation, an Orc, I decided to make him instead of the Shamanesses, and I'll replace the old Orcs later.
For now, he's mute; I want to extract his sounds from HMM7, they are archived in upk format. I've tried with various programs, but none of the ones I know can open it... Maybe someone can suggest how to extract the sounds?
I'm a complete beginner in modeling, but thanks to the detailed guide, I managed to create an Orc with perfect animation.
