From Hermann Schinagl:
Link Shell Extension provides for the creation of hardlinks, junctions, volume mount points, Vista's symbolic links, and a folder cloning process that utilities Hardlinks or Symbolic Links. Link Shell Extension, as its name implies is implemented as a Shell extension and is accessed from Windows Explorer, or similar file or folder managers. The extension allows the user to select one or many files or folders, then using the mouse, complete the creation of the required links such as hardlinks, junctions or Symbolic Links or in the case of folders to create clones consisting of hard or symbolic links.
I had tried previously to use Windows CMD box to create hardlinks, but never got them to work as I wished. This tool, (LSE), did the trick for me without struggle. After installation, works via a simple GUI Right-click process. Env: Windows XP SP3
Have not been able to get the Hardlink arrow overlay to show up on the Hardlink icon. But this could be just me... I will work with it some more. However, my issue with the icon overlay in no way counts against the basic product function.
Highly recommended for the technical and sort-of tech user (the only folks likely to want to be setting up Hardlinks in the first place). Give it a try.
