Emulating Mod Organizer's Virtual File System

[RoboticWater]

Hi, I'm working on making my own mod manager similar to Mod Organizer as part of a computer science independent study. I've figured out how all the GUI bits, but I'm having trouble figuring out how to code Mod Organizer's signature virtual file system. At first I thought of creating symlinks with my code, but this guide put me onto the trail of "hooking," and specifically recommended trying EasyHook. While I think can understand the underlying concept of hooking (essentially intercepting signals from the OS and redirecting them for whatever purpose), I don't really know how to make the hook actually redirect files. After a few hours of digging all I've learned is that documentation and examples of this hooking system are scant.

 

My question is: how might I create this on the fly file system or make Windows "pretend" a directory full of mod files is somewhere else.

 

If anyone knows a good resource for this kind of hooking or has better approach to my problem, I'd appreciate the help.

You could examine the source code of MO on Sourceforge. It doesn't use EasyHook though.

I took a look through it but without proper context it ends up looking like a lot of gibberish. I could likely work my way through it with enough time; however, I'd rather work from the ground up than work backwards from someone else's code if I can.

 

Thanks for the advice though.
