I don't seem to have storage on my PC. Can't find whats taking it up

[JC_9988]

My PC is supposed to have 1TB of space of which I seem to be taking 870GB surprisingly. When I try to check out what it might be that is taking up all that storage, the PC doesn't seem to find it. I've tried deleting and deleting but still can't find what are the files taking all that space. I've tried scanning my pc and apparently there are no signs of viruses or malware. I use my pc to play video games using the steam(I think steam might be the problem its just a wild guess which I don't know how to check out) launcher mostly. My hard drive is starting to fail at this point, its messing up the booting of the computer. 

PS: My Hard Drive previously had some sort of fail where it all had to be recovered and copied and start from scratch again but it left this folder with everything file and app I had but too my knowledge I deleted it all, at least, I think.

Please empty Recyle Bin first and use File Explorer to see which files or folders are the culprits then delete them if you don't need them.
