Solved Main drive mysteriously full

Specs: Windows 7 64 bit, i7 4790 \ 16 Gb's GSKILL 1600 DDR3
I have Win 7 64 bit installed on a 120Gb SSD, plus some apps and programs. I re-installed Windows on the drive about a month ago when I bought a new Mobo and CPU. I can't remember the exact amount on the drive a few days ago, but it's usually around 70 Gb max. Before re-installing windows the drive had about 40Gb free, and that was a years worth of accumulated programs. I have even less installed on it now.

The strange thing is that today I noticed the drive was in the red zone when I saw it in Windows Explorer My Computer. It shows only 10Gb free of a possible 111Gb. This makes no sense to me. I opened the drive in an explorer window, highlighted all files and folders, and right clicked to check properties. It shows only 32 Gb - which is possibly a realistic amount considering the fresh install a month ago. I have two other HDD's which contain media and games - none of my games are installed on the C drive. Here is a screenshot of the contents of the C drive as they appear in the explorer Window.

Like I say, right clicking those files and folders and checking properties shows only 32Gb. I emptied the recycle bin which contained 12Gb of material and that didn't change the available space on the drive. Neither did running disk cleanup.

So I'm totally stumped as to why it's showing full. What else could account for the drive showing so full?

✔ Best Answer
What does Disk Management say about it? Did you partition the entire drive?

Is hibernate enabled?

Do you have a large page file set?

If you don't know how to check these you could probably just Google it and find a good tutorial .

In Disk Management it shows the drive as having a 100Mb NTFS System reserved partition that is Healthy (System,Active,Primary Partition)
a 111.69 NTFS partition that is Healthy (Boot,Page File,Crash Dump,Primary Partition)

I have the power settings on Performance and under Advanced Power Settings I've set the Hard Disk to Never turn off.

As far as page file goes, I have it set to 16Gb (16221 Mb) in VIrtual Memory - recommended shows 24331Mb. That is allowing Windows to "Automatically manage paging file size for all drives"

So I'm thinking this all looks pretty normal unless you have a suggestion about those settings?

EDIT: I also turned hibernation off through a cmd prompt:
powercfg /hibernation off

Reboot and no change to the drive

I found the culprit. System restore was set to use up to 50% of the drive!!!! It was currently using just under 50Gb. I don't know why I didn't think to look there earlier, but at least I've got it now. I'm back to 60Gb free.
Thanks for contributing anyways NT56erbx

Update is available that enables you to delete outdated Windows updates by using a new option in the Disk Cleanup wizard in Windows 7 SP1
