Extraction Evoland 2

Hello. I am a newcomer in the world of ripping and I'd really like to be able to retrieve and view textures and model Evoland 2. But can not find the way to open the file res.pak. Given the size of the file, I'm almost certain that this is the one that contains all the resources.
If someone just put me on the path I shall be delighted.

Sorry for my english, i'm french.

Good day to you.
Thank you.
