Hard Links in Window are called Junctions and are useful for example to create an Assets link in current folder and link to one in Dropbox.

First change to the directory where the link should be placed:

CD %home%\Documents\Luxology\Content

Then enter this line at the Command Prompt to create the Junction:

mklink /J Assets "%home%\Dropbox\Modo\Assets"

Note the location of your Dropbox and Content folder may vary this is the default location.
