Windows show low disk space, win dir stat shows different space

Hello to all.

I have a problem with my windows 7 pro laptop that shows only 7,49/100 GB free memmory. I tried to delete all shadow copies and previous versions. Also did chckdsk /f which give me 0 errors, tried to search in hidden and OS files, but there arent any big files, diskcleanup with system files cleaned about 1 gb.
Then I downloaded winDirStat which shoved me that I only have 43Gb of data on my c: drive. I don't have any ideas what could be done to increase free disk space. Please help

In My Computer, click the Tools menu then on Folder Options then click the View tab and tick "Show hidden files and folders" then untick "Hide protected system files and folders", click Apply and OK.

Then, go into c:\ windows and delete all the files in blue which statr with a $ symbol. They are only folders that once contained Windows Updates you no longer need to keep. Then scroll down to the Software Distribution folder and to Download. Empty that folder.

Look in Control Panel>Power options and make sure Hibernation is turned off then in System, adjust the size of System Restore so it takes up only 4% of the disk space.

Restart the computer and see hwo much space you freed up.

In WinDirStat, under the Options menu, be sure "Show Unknown" is checked.
Then see if you can see the extra space.

This is going to be my last post for the next ten days or so till I log in from Atlanta sometime after 13th April. (Till then I will be on high seas and I can't afford the internet charges on the cruise ship.)

Try deleting the temporary folders and files as detailed below.

Close Internet explorer or any other browser you may be using.

Close all running programs.

To delete your Windows temporary files on Windows Vista, Windows 7, and Windows 8:
  1. Click on Start (For Windows 8, hit shortcut Windows key + R)
  2. Type %temp% in the search box, and then hit the Enter key.
  3. Select all the files/folders.
  4. Press Shift+ Delete key on your keyboard.
  5. When prompted if you are sure, choose Yes.
Some files currently in use may refuse to be deleted. Skip those.

See how much space you have regained.

Bye bye .

That is a limitation in WinDirStat.

If you download and install Treesize Free, it will do a better job of showing what the unknown files are.

But most likely they are Volume Shadow Copy files (System Restore Points) which WinDirStat inexplicably does not know anything about.

To check Go to System Restore (Start > Computer > System Properties > System Protection > Configure) and look to see what it says under Disk Space Usage. If it is approx. the same size as the Unknown space then there you go.
Check the percentage slider. It should be 5% or less than 5GB on most systems.
If it is not, change it. You could also delete all restore points here and start off fresh by creating a new one.

If it is not System Restore than it will take further digging.

As mentioned, WinDirStat is showing incomplete information.
There are a number of folders in Windows, some of which consume considerable disk space, that by default even an elevated admin account does not have access to. WinDirStat runs under the users account and is unable to see the contents of these folders. If it cannot see the contents of these folders it is unable to account for the disk space they consumes. Windows Explorer has the same limitation.

Treesize Free uses a service that runs under a system account that does not have this limitation and can thus provide more accurate information. Note that with a complex file system such as NTFS the determination of a folders disk space is only an approximation. For a number of reasons this is unavoidable.
