For many of you, I'm sure you've encountered the same frustration I did when working on custom rulesets; that is having to change the .pak file to a .zip, edit the files and the change it back. That gets really trying, really fast. Fortunately, in Windows, that's easy to fix. Friendly warning before you try this, editing registry files can TOTALLY fubar your system if you don't know what you're doing. Make sure, for example, that you don't have other programs that use the file extension .pak.

Anyway, it's a simple registry hack. You just need to make windows recognize .pak files as compressed folders. All you need to do is run CMD as Administrator (Programs->Accessories, the right click command prompt and select Run as Administrator).
