    Every single folder, shown in the screenshot, is 0 bytes. That folder should not be deleted, if you delete it, Windows will stop functioning. – Ramhound Sep 3 '16 at 18:35

I found that a folder called $Extend is 550Gb

$Extend is a system reserved folder used by NTFS v3.0 or later. These files are required by the OS and should not be deleted.

$Extend - A file system directory containing various optional extensions, such as $Quota, $ObjId, $Reparse or $UsnJrnl.

...

v3.0: Released with Windows 2000. Supports disk quotas, Encrypting File System, sparse files, reparse points, update sequence number (USN) journaling, the $Extend folder and its files. Reorganized security descriptors so that multiple files using the same security setting can share the same descriptor. Commonly called NTFS 5.0 after the OS release.
