Before you begin:
NTFS supports aliases (hard links) for files. Up to 1023 aliases can be created for a file. Each alias, a hard link to the file, is a directory entry. After creating a hard link, you can access the file using not just its name but the alias as well.

DO declare

LOCAL cSource, cLink
cSource = "C:\aa.txt"
cLink = "C:\aa_hl.txt"

IF CreateHardLink(cLink, cSource, 0) = 0
    ? "CreateHardLink failed with error", GetLastError()
    RETURN
ELSE
    = ShellExecute(0, "print", cLink, "", "", 3)
    WAIT WINDOW "Press any key to delete the hard link..."
    = DeleteFile(cLink)
ENDIF

PROCEDURE declare
    DECLARE INTEGER CreateHardLink IN kernel32;
        STRING lpFileName, STRING lpExistingFileName,;
        INTEGER lpSecurityAttributes

    DECLARE INTEGER DeleteFile IN kernel32 STRING lpFileName
    DECLARE INTEGER GetLastError IN kernel32

    DECLARE INTEGER ShellExecute IN shell32;
        INTEGER hwnd, STRING lpOperation,;
        STRING lpFile, STRING lpParameters,;
        STRING lpDirectory, INTEGER nShowCmd

My comment:
Need to check whether short names like MYFILE~1.DOC are created as hard links to files with long names.

Some uses for hard links include:
- Providing different levels of access to a set of files by creating hard links via paths with different Access Control Lists (ACL).
- Organizing files into different directories without having to copy the data.
- Different names for the same file can be used to evoke different behavior for applications (including aliases for an application"s own name).
