Windows 10: My C: drive is suddenly almost full and I don't know how this happened

I was notified today that my C: drive only had about 3GB of space left! After doing a lot of cleanup using Microsoft's disk cleanup I was able to clear to 9GB of space, but I still don't know how I've apparently used up over 150GB when all I've downloaded were Steam and two games the sims and planet zoo - shouldn't be more than 20GB each? I downloaded treesize to see if there are any large files I can delete, but I don't really know which files are okay to delete. What should I do?

Windows 7 Snipping Tool / (Screen Shots-Capture)

1. In the Control Panel > Folder Options > View Tab first check ( tick ) the Show hidden files, folders and Drives and then Apply.
2. Now navigate to C:\ Program Data \ Microsoft \ Windows \ Start Menu \ Program.
   
3. Inside this Program folder , you will find the 'Accessories' folder.
4. Drag and drop the Accessories Folder on your Start Menu or All programs.

Did this work ?

If all works again i suggest to go back to Step 1 and re-select Don`t show hidden files. folders and Drives then Apply. so you don`t accidentally delete some of these.

 

Unallocated Space to C Drive
