A few months ago I deleted a game that was taking up a lot of space on my Mac (all files from the game were removed). It was a game I downloaded through the Steam application, which I have since moved to another disk, so the game should not be taking up any space on my computer any more. However, when I manage my storage with System Information, a file from the game (I think the file was the game contents originally) still shows up as taking 13.9 GB of space on my disk. The "Show in Finder" button doesn't do anything when I click on it and I am unable to delete the file from inside System Information. I can't locate the file anywhere inside Finder so I'm assuming the file no longer exists on my Mac.
This is pretty annoying because it is falsely taking up disk space. Is there a way I can delete this file once and for all?
I am running macOS Mojave 10.14 and I've had this problem since High Sierra.
