Saving CFS 2
After I build a new basic theater or campaign installation of CFS 2 (MTO, ETO, Nomonhan, SCW etc.) on my computer, I zip it up and then save it to an external solid state hard drive. That way it should not only last a long time, but when I want to rebuild or replace that theater, I can just unzip and place the archived basic theater (with all the proper planes and scenery) straight into my computer and be flying over Malta or Kursk within just minutes.
With external hard drives now measured in the terabytes, you can save a lot of various files, missions and installations, not to mention photos and other documents for use later.
