[CURRENT ISSUE] Sims 4 already running

@Nyythajointt  The second and third screenshots show the free and total space for your C drive, called Windows (C🙂 in Windows parlance, which we already knew.  The first shows the size of the Windows folder, which is about right and much smaller than the size of all the files on C.  So the question is what else is taking up that space.

In your first screenshot, click on each of the other folders in turn and find out how large they are.  I mean Program Files, Program Files (x86), etc.  For any folder less than 5 GB in size, ignore it.  For anything larger, open it and repeat the process.  For example, if you click Program Files (x86) and it's 20 GB, open it and click each folder inside, maybe Origin Games and Chrome and some other stuff.

The first screenshot you posted has the info I'm asking about—size and size on disk—so you could just write that out instead of posting a bunch of screenshots if it's easier for you.  Or just post the screenshots.  It doesn't matter to me as long as I get that info.

Please don't compress the data on C, at least not yet.  This can cause certain applications to not work correctly.
