About your journey....wow - what a waste of time. You could of asked about the .xnb format here, as its what all content is compiled to, sound, images, etc for Xna projects(like you stated). Xna itself, ofc, can open its own file and save, with 1 line of code, to either jpg or png. There was no point in decompressing the .xnb, as you can see. However, the pkg, yes (as far as i know, which is nothing about them). Im not trying to troll, but all those hours of hard work could've been minutes if you asked a few questions here -.0
