Semantic gymnastics. The fact is there is nothing in windows equivalent to a symbolic link in Unix. Junction points (correctly termed reparse points) are quite similar to a Unix hard link. Still not the same. Whatever name you want to give it, there is nothing in Windows that will do what a symbolic link does for Unix. Received on Sat Jan 12 2008 - 07:59:05 CST
