I have a 60GB SSD showing as 55GB in properties, installed with Windows 7 as c: drive.

I selected everything in C drive and went to properties and it says 37GB but when I right click on the C drive and go to properties it shows 48GB used.

I am trying to understand where the extra 11 GB is.

I have changed the page file settings, and changed it to use 512mb, putting the main page file on an HDD disk but this made no difference after a reboot.

I have also made sure the recycle bin is empty.

Can anyone suggest what might be consuming the missing space?

It's likely shadow copies and system restore points. –  Rob Nov 10 '11 at 4:31
    
Can I move those to another disk? –  Ryan Nov 10 '11 at 4:45
    
I'm not sure. I've been using linux for a while now, and haven't run into space issues in a long time. –  Rob Nov 10 '11 at 4:53
    
No worries, thanks for replying though. Always wanted to learn and test out linux dont know where to start. Oh well, will save that for another thread :) –  Ryan Nov 10 '11 at 5:00
    
The easiest way to use a virtual machine. VirtualBox is free and easy to set up, and a great place to start trying new things. –  Rob Nov 10 '11 at 12:12

How much ram do you have?

Windows 7 creates a hibernation file on c:\ . For example, my hibernate is 3G and the pagefile is 4G.

There are a few other hidden windows files/folders that will not show up when you select all in c:

A tool like http://www.piriform.com/ccleaner will help you clean up worthless files off your windows drive.

16 gigs... I wanted to mention that in the OP, but was not sure if it was related as 11 gigs are missing but ram is 16 –  Ryan Nov 10 '11 at 4:45
    
I am using linux to see the hibernate file, but if you go in explorer, file / folder settings and uncheck/check view all files, including hidden and system files, you will probably see the hibernation file in c:\ –  Martin Samson Nov 10 '11 at 4:47
    
Can I move that to another disk thus freeing up space to install some virtual machines? –  Ryan Nov 10 '11 at 4:53

To completely turn off hibernation and clear the file, open an elevated prompt and type: powercfg -h off –  Martin Samson Nov 10 '11 at 4:56
    
Can you tell me a little more about what the effects of that are? I mean if I am running something (like rendering) and dont touch the pc for 2hrs does it just shut off because it cant hibernate or...? –  Ryan Nov 10 '11 at 4:59
