Just key in it on the command line to see the options:
Creates a symbolic link.
Default is a file
symbolic link.
/H Creates a hard link instead of a symbolic link.
/J Creates a Directory Junction.
Link specifies the new symbolic link name.
Target specifies the path (relative or absolute) that the new link
refers to.
Understanding the Options.
MKLINK link target
Using the command without any extra options creates a soft link to a file.
/D creates a symbolic link, or a soft link.
/H creates a hard link, which points directly to the file.
/J creates a “Directory Junction”
A Directory Junction is actually just a hard link to a directory.
This is a feature that existed prior to Vista as well.
This is troublesome if you expect to use this feature on a web server or a file server.
Deleting Symlinks
To delete a symlink, you’re able to just delete the link.
Just confirm you don’t delete the original file.
