How can I delete local content from a game not in my list in Steam?

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.

  • Is there any way to start Steam in offline mode without logging in first?
  • How do I find out what version my Skyrim is patched to?
  • Do I need to buy the same steam game twice for two different operating systems?
  • Shortcuts to launch game with different launch options in Steam
  • How can Steam be prevented from downloading a billion copies of DirectX?
  • Will the drop counter reset if I craft a badge?
  • 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)?

    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,

    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.
