The NTFS file system defines various ways to redirect files and folders, e.g., to make a file point to another file or its contents. The object being pointed to is called the target. There are three classes of links:
1- Hard links, which have files share the same MFT entry (inode), in the same filesystem.
2- Junction points, which are similar to hard links, but defined for folders. Only accepts local, absolute paths.
3- Symbolic links, which record the path of another file that the links contents should show.
