Hard Disk (C:/) Takes Up Too Much Space

Hey Guys,

So I have a 200 GB Hard Drive on my computer. A couple of days ago I got a notification mentioning there was not ten GB of space left. I was surprised, but I assumed I just had more on it than I thought. However, since then I have re-installed Windows for my own reasons and was surprised to find despite removing all documents and applications in the re-installation, I only had 90 GB free. This leaves 110 taken up by an unknown cause. I could not find many large files in file explorer when I searched for large files (file:gigantic). I'm sure this is not normal, and I would greatly appreciate help.

Thanks,
JTechnology

Download: TreeSize Portable Free and run. It should give you some idea.

Thanks! I found I have 83GB on Windows.old and 14GB on Windows. Is Windows.old a remnant of my old windows? Can I delete it without issues? Thankyou for your help

So I permanently deleted the Windows.old folder as it was to big to go in the recycle bin, where it would have used storage anyway. Thankyou for all your help-SOLVED!
