Moving cubase content to other drive.. How ?


I am running short on system diskspace.(windows 7)
So i want to move the content of Halion Sonic and Halion 5 to another internal drive.
How to do that the right way ?
I am a windows noob (just coming from mac) so i dont know where that content is located now on my system drive.
Would be nice to have an explanation in detail.

Many thx !
