Working drives or keep space usage low

Can I or do I have to set up any working drives for UE5 or the marketplace or the Quixel bridge?
After working a while in UE5, I noticed that my C:drive was much fuller than before.

Are there files stored in the C:\Users.…\AppData.… or being written in there that might cause this? And how can I clean it?

Thank you very much for any intel about this.
Best regards
