How to put Mission File in Editor?

[Statik (DayZ) 2695]

Hey guys, so I'm trying to put a DayZ mission file in my ArmA 2 mission folder. I have the mission file, and I know where to put it, except it's a .pbo file, and I believe all the missions in my mission folder are .zip (can't remember, but they're a folder, not a .pbo).

How would I go about getting the mission file into my missions folder correctly?

Thanks,
