You're welcome, and I need more space too. >,<
(I have the full game in a virtual layer, though. That makes it nice and easy to mess with.)

It allows you to make virtual layers that you can active and deactivate. I use it to make "capsules" of games I install so that I can easily move them to other computers. I also use it when I'm not sure about a file that I want to open. (So, if it installs spyware, it's only installed on a virtual layer that I can remove easily.)
That was kind of random, but you may find it useful to install this game on a virtual layer.
