Mklink create Symbolic links (win7 introduced); A shortcut-like arrow appears on the Created symbolic link file
The Mklink command under Win7 can create different forms of file or directory links by specifying parameters, broken down into hard links, symbolic links (symbolic link), and directory joins (Junction) of three. The
(1) Symbolic link (symbolic Link)
establishes a soft link equivalent to creating a file (or directory), which is used to point to other files (or directories), and the shortcut to win is somewhat similar.
Deleting this link has no effect on the original file (or directory), and when you delete the original file (or directory), opening the link will prompt "location not available."
(2) directory join (Junction)
functions essentially like symbolic links. The difference is that the directory join automatically references the absolute path of the original directory when it is established, and the symbolic link allows a reference to the relative path.
(3) Hard link
Mklink [[/d] | [H] | [/j]] Link Target
/d Creates a directory symbolic link. Mo considers file symbolic links.
/h creates a hard link instead of a symbolic link. The
/j creates a directory join. The
link specifies the new symbolic link name. The
Target Specifies the path (relative or absolute) referenced by the new link.
