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)?

    If you can see it in the installed programs list (Programs and Features) you can try uninstalling it there. If not, then you can safely delete the folder.

You can use the Steam browser protocol to uninstall it:

Deletes the specified apps' cache files.

Generally you can find the ID you need by looking at the URL of its Steam store page — for example, http://store.steampowered.com/app/42700/.

Call of Duty: Black Ops' ID is 42700, so the link would be steam://uninstall/42700. Enter that into your browser's address bar or the Windows Run dialog (Win+R).

You can also pass it directly to the Steam executable as an argument:

Steam.exe "steam://uninstall/<id>"

In this case, it left behind a few files (~10 MB for me). Those can safely be deleted.

  • folder: steamapps\common\call of duty black ops
  • file: steamapps\call of duty black ops mp binaries.ncf

The multiplayer component actually has a separate ID (42710); uninstalling that ID did nothing for me, but you may want to try anyway, just to be sure.

    Nice, that worked. Where do I see the id for a specific app?

    @JuanManuel On its Steam store page, generally. It's in the URL. (Example: http://store.steampowered.com/app/42700)
