Game mysteriously filling up HDD space?

Hey, everyone. I wonder if anybody else is experiencing this.

Any insights would be greatly appreciated.

I have 2K19 installed in Windows 10 on my D drive, and ever since I started playing, my C drive space keeps filling up, and I don't understand why. Seems to mostly happen after or during gameplay.

Anybody else seeing this issue? Any thoughts?

Further note: Restarting the PC seems to bring a lot of the missing hard drive space back but not all of it. So strange.

Is it around 2Gb ?

Much more space than that. Why?

The game stores a cache of temporary files during gameplay, mostly things like replays.

Thanks for the input!
