Windows 10: My drive C only has 2 gb free left when its actually has 30 gb left

So i have an ssd for my drive C system it has 232 size, yesterday i moving file around 10gb+ and have a free 16gb c drive but suddenly i lost almost half of it and it became 8gb, i try system restore hoping maybe its gonna fix it, its just make it worst after the restore its done it became 3gb free. I try folder size to see whats happen and it didnt show any new file that can cause it, the biggest file i found that created on the day it happen only pagefile.sys. since i cant found the problem with folder size i calculate the size manually, after adding all the size of the folder on C drive it

My New Volume D: drive has only 71.3 gb left from 120 gb even though the drive itself has no files.

Hi so yesterday i just downloaded a game to my pc(in another drive) and the space in the drive decreased even more. Before it was 71.3 gb left and now it is 31.1 gb left. Are these 2 things related?
