Installing Gears of War

I just finished downloading gears of war, and extracted all the rars to get 81 files.
rzr-gowa.sfv
rzr-gowa.txt
rzr-gowa.001-rzr.gowa.079
how do I install?
Answer #1
You need to extract the .iso from the ‘rzr-gowa.001’. Right click on it and select: Extract to rzr-gowa.001
This will extract the .iso(or indeed other image file type)into a folder. Do that and report back with what you have.
Answer #2
What program do i use to extract rzr-gowa.001?
Edit: Nvm, i got it. Just had to update winRAR. Thanks man, peace out.
Answer #3
The .001 extension usually indicates HJSplit. Google will turn it up its freeware.
Maybe give us a screenshot of the containing folder?
