Unity taking space randomly

so i started downloading unity in unity hub and allocated a new destination on my d drive since i have alot of space on that drive but in the end unity still taking space in my c drive and every steps failed i downloaded it two times with just the editor and it still did not work but its taking space on c drive i have around 12 gb and i lose 8 gb out of nowhere and i cant find it and now i have only 900 mb left on c drive

its starting to annoy me that unity just took away 8gb and did't even let me find it so i can uninstall the old folders i really need help to find this folders

 

i use this free tool to check what is using up the space,
