A Link can be so called Hard Link linking one file to a target file, or a 
Soft Link linking a folder to a target folder. Soft Links are also called Symbolic Links. 
Third link type is Junction, basically a hard link but as hard links can only link files 
we need to use junctions to link folders.

    mklink /J "BTSync\Documents" "Documents"
    mklink /J "BTSync\Downloads" "Downloads"
