I played the free weekend for Call of Duty Black Ops and I decided not to buy it.
However, now I have a folder taking up 8 GB of my SSD space in
C:\Program Files (x86)\Steam\steamapps\common\call of duty black ops.
The game is not listed on my game list in steam (where I could right-click and select "delete local content")
Is it safe to delete that folder directly? Is there another folder I could delete to recover more space? Is there a way to do it from Steam (this would be preferred)?
