Greg,

There are hard links in Windows also. Here are some references.

Fsutil: hardlink (I think this is native to Windows XP)

There is a tool for scanning for hard links in the Windows Server 2003
Resource Kit Tools. Hlscan.exe: Hard Link Display Tool


I've attached a Perl script that will create hard links.
