Get into detail best solutions


Please Download WinDirStat  to view disk usage and statics and Unlocker if you are not able to delete a file or folder.


Here is the screenshot of my C drive on WinDirStat.

windirstat2 As you can see my Users folders is consuming much of the space as i have many downloaded files.

On Windows 7 or 8 windows file size of 10 Gb is normal,check the size of your program files if you have any unwanted applications installed see it on programs and features and remove it.

If you expand +Files folder you can see pagefile.sys (virtual memory) file which is around 2 Gb or it can be more do not delete the file instead we will move it to some other drive .


Moving the Pagefile.sys


To Move pagefile.sys to other drive open Control Panel\All Control Panel Items\System then click on advance system settings click on advance tab then under performance click on settings on performance options click advance tab under virtual memory option, click on change.

If you cannot find type just this command on Run press window key and R on input paste %windir%\system32\SystemPropertiesPerformance.exe

move page fileOn the Virtual memory uncheck automatically manage paging file size for all drives then on the drive letters select any other drive where you want to move the pagefile.sys check system managed size [recommended] or custom size and click set in our case its D:  and now select the drive from where you are moving the page file in our case its C: where we do not want any page file to stay check no paging file and click on set, this time click OK and then restart your computer.

The pagefile will now move to D drive and we get 2 Gb more free space after the restart is done.


Manage windows.edb and search search.edb Files


Another reason your C drive is getting full is because the size of Windows.edb or Search.edb file to view the files is increasing drastically on Run type

C:\ProgramData\Microsoft\Search\Data\Applications\Windows hit enter click continue to open the folder, if you find the size of the files windows.edb or search.edb is unusually large you can delete the file to delete windows.edb or search.edb open command and type Net stop wsearch then delete windows.edb or search.edb now again start the service Net start wsearch.

Now press window key In the search box type indexing options on windows 8 simply type Indexing Options and click on it, click Advanced then click Rebuild on the Indexing Settings tab click OK to confirm.


Reduce Space Used for System Restore or Delete old ones


Type %windir%\system32\SystemPropertiesProtection.exe under protection settings select C drive click on configure in this new window under disk space usage decrease the Max usage space used for system protection if required.


On this [Regain disk space] post we have given instructions to remove system restore points and shadow copies, but we see its much easy and safe to with CC cleaner.

Launch CC Cleaner click on Tools tab and find system restore. It will then show you the number of restore available you can select old restore points and remove. Note CC cleaner will always save the latest one for safety.

remove system restore
Hope this article helped you gain ample amount of space on your computer.
