And I would like to download COD Bo4 on my C: program, but not enough memory on it. What can I delete?

I have on my C: actually almost nothing more that I can delete. I have only Fortnite on it, the rest are things from my AMD but I would rather not delete them because I just do not know what that is. And the rest is Windows Photo Viewer and stuff like that. Do you still have tips?

Yes. Buy a hdd.

Purchase larger / second plate.

Then you should reorganize you the plate, otherwise sooner or later your Windows, that needs space, for example. For updates. Greeting
