Survivalcraft .PAK ripping

[SniperDude2745]

I just got interested in Survivalcraft and it really cool! I thought I should try ripping models/sounds/etc from the game. So I got the windows version and I needed to get access to the WindowsApps folder inside program files. I did and I found the Survivalcraft folder, inside was mostly just .dll files and .xml files and there was one file that seemed like it might hold the sounds and models and stuff "content.pak" but this wasn't a normal video game .pak file because programs like QuArK and pak explorer wouldn't open it! I haven't tried any other programs yet but this must be a different type of .pak file it must have a different format. I opened it up with a hex editor and the first line on the top right read PAK.N3. The hex of this file was strange because it was made up of actual words. Here is a segment of it 
.Shaders/Opaque.Engine
.Graphics.Shader....Ñ....
Shaders/AlphaTested.
Engine.Graphics.ShaderÙ...Þ....
Shaders/Transparent.
Engine.Graphics.
Shader»...¢....Models
/Human.Engine.
Graphics.Modela"..ê(...


can anyone make me a quickBMS script for it?
I really need help! I'll do anything
