Free space on C:

Sat Mar 30, 2013 10:01 pm

In windows 7, when I right-click/properties my C: drive, it shows used space: 90.8 GB. However, when I select all folders/files on the C: drive (all hidden files are included) at the root directory and then right-click/properties, the size reads as: 77.8 GB. What's the reason for the delta? Is there a way to reclaim this space?

I have a Intel 520 120GB SSD ( ... 6820167093).

There can be several potential reasons for the discrepancy including hidden folders & folders where your user account doesn't have permission to do the file size calculations under explorer. This blog has some more information on a similar situation.

Pagefile and hibernate, most likely.

DancinJack is right. If you never use hibernation, you can disable it by running Command Prompt as administrator, then type this in

powercfg -h off

You could save about 3-4GB there. You can also download this nifty free software called Treesize to know exactly where hdd space is being taken up.
