Win8 appears disk space and file size does not match how to solve?

Solution:
First, you need to open the display hidden files and system files;
Second, the disk contains a folder similar to "System Volume Information", even if we open the display hidden, view the volume The capacity will not be calculated. If you don't believe it, you can right click on the System Volume Information folder to view the properties. The general volume is 0 bytes, because these folders are not only hidden, but also protected by NTFS permissions. Directly select all content view properties, and see the size of the file does not contain such folders;
Note: System Volume Information folder is the folder where the system restore point is stored for system protection.
