Where to find space for 1st hardrive?

Caracarn

Greetings. I have installed Alpha2 on my 2nd harddrive but now I understand it stills saves many files on 1st harddrive (C) and I had many random crashes lately. Now I discovered that C drive is full hence probably causes these crashes.
Where do you find I asumme crash reports that takes up space?
I have located on C drive local app and got to the point of choosing Launcher folder or Webview2 folder. The launcher one got a crash report folder but not many files there that takes up any space.
I hope any cunning one can help me on this

Update. I think I found it under AOC folder
