Removing Arma 2 OA Files UNDETECED

I've found a way of playing Dayz without the files in common folder. For example i can see through barracks, walk through houses, rocks and zombies can't see me neither can i see them when playing on any Dayz Server.
I've used this method for like 3 weeks and nothing happened yet so I guess its safe.
I know my english is shit but if you guys want i could post a tutorial on how to do this!
Byee

zombies cant see me? oh yeah make a tutorial man!

Please do! This is some crazy shit!

Tell us how to do this.

3 weeks have passed he must have died
