Apps and Features taking up 131G but nothing big in there

Hi MRawlins

I am Dave, an Independent Advisor, I will help you with this . . .

Windows File Explorer is not great when it comes to working out where your hard drive space is being used

Click the link below to download a small free utility called Treesize. Using that tool, you will instantly see where this space is being used

To run TreeSize, right click its icon and choose Run as Administrator . . .

Please provide a screenshot of your C drive in that TreeSize utility, so I can see your hard drive and work out where that space is being used and if there is an underlying problem . ..

Found it. 

Neither Steam nor the storage-hog game in question even showed up as occupying space in the Apps and Features window. 

That and an iTunes backup of my phone appear to be the culprits!

Thank you!

Hi M, I am glad you found the culprits, stay safe!
