File System - ( Symbolic | ln | Soft) link - File Alias - Symlink - Junction - Reparse Points


A soft link, symlink or a symbolic link is a file that redirects (link) to another file.

It's the alias functionality of a file system.

Unlike a hard link, a symbolic link can link to any file on any computer.

Operating System
