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.

Hardlink Shell Extension is a free and useful utility that can implement 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.

Hardlink Shell Extension is freeware. However, if you enjoy using Hardlink Shell Extension and would like to help support its development, please consider making a donation.
