During the initial game installation (version 1.0), the game folder contains files named Data 1-6.orc.
Each patch adds similar files to the folder: Data 7-13 (patches 1.1-1.5.1).
I'm going to venture a guess that if you copy these files to a removable storage device and then put them in the folder of a newly installed game (version 1.0), it will be beneficial.
