Description

Hard link support for Windows does not work properly. There is some refactoring needed in the code. Also, the code currently executes the fsutil command to manipulate hard links. fsutil requires admin privileges on recent versions of Windows. The main features needed are the ability to create hard links to a file and count the number of hard links to a file. So we could use mklink to create hard links and write a custom executable to count hard links. Or use a custom executable to do both using Windows API's.
