The NTFS filesystem of NT4/W2K/WXP/WXP64 supports HardLink functionality, but HardLinks can only be created via the POSIX command ln, which is shipped with the Windows resourcekit. Even if with POSIX commands, HardLinks can only be created via the command prompt, which is a kind of a mess for many files.
The Link Shell Extension implements an extension to the Windows shell explorer, so that HardLinks, Junctions, and SymbolicLinks can be comfortably created via right mouse click on a selection of one or multiple files.
What's New in version 2.9.5.3:
Hardlinks can be enumerated under Vista.
Fixed a handle leak for HKCUSoftwareLinkShellExtension.
Removeable media support didn't work, when remote capabilities were switched off.
