My game is apparently taking 2.5 Terabytes of my hard-drive

My C:/ drive was completely full when i turned on my computer today (0 bytes issue), so i went to delete some stuff
and I saw how much val was taking up
I have absolutely no idea what could be causing this or if the number is even correct
if this is an issue with how the app is registered on windows it should probably get fixed for clarity
other than that
il be reinstalling this game 0_o
