Unknown file on C drive

Try using SpaceSniffer, looks like TreeSize can't even see it. You'll most likely need to open it as admin.

Could you clear your System Restore Points, please?

I did and it cleared about 1.9gigs, and those are stored in sys info folder right?

I had checked that before posting the thread

Hmm...

Is this a cloned system or did you install W10 from scratch?

I installed it from scratch( maybe 6 months back), when I changed to a new SSD

I just noticed that all 4 utilities are reporting completely disparate numbers for disk usage. WinDir says 90.8, TreeSize says 86/79, Disks says 83.2 and SS says 81.8.
