The "Shader" files contain graphics rendering code, in uncompiled form because that is dependent on the user's graphics card. Only one boot.pack exists at a time it contains data needed during the very first initialization (like the loading screen image). There are several types of pack files (in order of being loaded by the game): They can be opened and browsed by the PackFileManager (see "Other Tools" section below). Pack files reside in the data/ folder of your game installation and establish a virtual file system that is being loaded by the game. These are what's getting updated in patches (apart from the software themselves) and what's being edited when modding.
