1.Click Start - Run.
2.Type "regedit".
3.Go to
HKEY_CURRENT USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer.
4.On the right window of registry editor, right-click the empty space.
5.Choose New - DWORD Value.
6.Type the value name "NoLowDiskSpace" and press Enter.
7.Right-click the new key you've made and choose Modify.
8.On the Value Data type the number "1".
9.Press OK.
10.Restart your computer.
