What Are NTFS Symbolic Links, Hard Links, And Junction Points?

"NTFS 連接點" ( NTFS junction point ) 是 NTFS 檔案系統提供的一種能力，可以讓某一個 實體目錄 (Target) 直接 Link (連結) 到另一個 對應的目錄 (Junction Directory)，這與建立「捷徑 (ShortCut)」是個截然不同的概念。

Junction points are NTFS reparse points and operate similarly to symbolic links in Unix or Linux, but are only defined for directories, and may only be absolute paths on local file systems (as opposed to remote file systems being accessed).

A junction, also called an NTFS junction point, is a feature of the NTFS file system. It is pointer to a directory on the local volume, similar to a symlink. It can be accessed through the Windows GUI in addition to the Windows command line.

junction.exe 工具只是在 NTFS 磁碟機中建立和刪除 junction 目錄，自身並不會駐留記憶體佔用系統資源，執行完畢會立即退出。 junction 目錄是 NTFS 檔案系統的一個特性，所以 junction 目錄並不是 Sysinternals “發明”的，而是微軟。
