Windows8 reports incorrect disk usage on SSD

[SgtSpoon]

I have a very annoying problem ... The windows 8 file explorer displays my C: drive in red, claiming that i only have 1.7Gb free of 119Gb. The disk is a 128Gb samsung SSD (840 or 840 pro, not sure).

However, if i configure file exporer to display hidden files, then do CTRL+A and then ALT+Enter in the root of C:\, the measured size is 42.6Gb :s

I googled around a bit, and tried executing "powercfg -f off" in the command prompt. That frees up 6Gb, but i don not want to disable hibernation, i use it alot.

So, anyone knows where my remaining 76Gb went?

I tried using SpaceSniffer (nice tool), and it shows 68Gb of "unknown" space. This unknown space does not show up in any of my other disks. Should i be thinking in the direction of a root kit? My computer is running fine and dandy, no visible traces of any spyware (i am very vigilant about what gets installed)

Edit: i also tried running this command: "VSSADMIN LIST SHADOWSTORAGE"

Which reports:
Used Shadow Copy Storage space: 0 bytes (0%)
Allocated Shadow Copy Storage space: 0 bytes (0%)
Maximum Shadow Copy Storage space: 1.19 GB (1%)

Edit2: ok, problem solved. I tried another tool called treeview which painted another picture:

Apparently when bringing up the properties of a folder in windows file explorer, folders that are only accessible by an administrator dont add to this total ... that sure sounds logical now but i didnt really think of this. I deleted everything and now have 70Gb of disk space again 🙂

Just wondering how did you get 70Gb of Windows/temp files?

I did find out I had @4.5 Gb of c:NVIDIA\ files
and realized the entire directory can be deleted after installing the drivers

No idea. I'll be keeping an eye on that folder.

Already back at 3.9Gb after one day ... all logfiles named MSI*.LOG (example: MSI1a69b.log)

I think this is the culprit:

Yep, the last link seemed to fix it ... temp folder is still empty.
