My C Drive in windows 7 is nearly full but is not real

I installed my Windows 7 in 3-4 months ago and it ran very well until yesterday. My C drive is about 40Gb. The combined total of all the visible folders in the root directory of my C drive is 16Gb (including the Windows folder), but my system tells me that I have only 1.13Gb of free space. I haven't installed any Programs and Updates. What can I do?

Solution 1:

Run chkdsk /f. If the problem still occurs, you might want to use a utility like TreeSize to see if there are any hidden files taking up space. Although it's also possible that your HDD could be dying...

Solution 2:

IT is because of your PageFile . page file is not visible until you disable the "Hide protected operating system files" on folder option. after that you can see what is the exact cause of Low Disk Space. it is good to run a Clean Disk but it is not a solution. in such these cases you should handle PageFile your self by going to Control Panel > System > Advance > Performance Options > Advance > here change the size of virtual memory. do not allow windows manage it.

and choosing a size for your page file that can suit your HDD capacity.

I hope this will work. let us know about the result.
