Which one is correct mv or Path#move?

[Rajendra Gutupalli]

Hi Alan,

I see difference in behavior between command mv and Path.move(). I 
created and moved a hardlink to a assigned drive (using subst command )
for a directory in C:\.
After moving using mv the link count for the file to which hard link is
created is reduced but after moving Path.move I don't see any reduction
in link count.
Please see the following result in command line and using program.

But if I assign a drive for a network folder in C drive using net
command ( net use M \\rajendra\temp : where temp is in C drive)and move
the hard link to this drive I see link count is reduced in both cases
(ie. using mv and Path.move).

<command line>
C:\>touch testfile

C:\>ls -l testfile
-rwxrwxrwa   1 R.+Vittal       None                  0 Jul 31 13:35 testfile

C:\>fsutil hardlink create testfile_hl testfile
Hardlink created for C:\testfile_hl <<===>> C:\testfile

C:\>ls -l testfile
-rwxrwxrwa   2 R.+Vittal       None                  0 Jul 31 13:35
testfile (link count here is 2)

C:\>subst O: C:\TestDir

C:\>mv testfile_hl O:\testfile_hl

C:\>ls -l testfile
-rwxrwxrwx   1 R.+Vittal       None                  0 Jul 31 13:35
testfile (link count here is 1)
</command line>

Executing the following code: (There is no reduction in link count)
<Result>
linkcount1 2
linkcount2 2
BasicFileAttributs are same after moving hardlink
</Result>

<code>
import java.nio.file.*;
import java.nio.file.attribute.*;
import java.io.IOException;

public class MoveHardLink {

    public static void main(String... args) {
        Path path = null;
        Path targetDir = null;
        Path hardLink = null;
        Path target = null;
        try {
            path = Paths.get("c:\\testfile").createFile();
            hardLink = Paths.get("testfile_hl").createLink(path);
            int linkcount1 = Attributes.readBasicFileAttributes(path,
false).linkCount();
            targetDir = Paths.get("O:\\TestDirectory").createDirectory();
            target = targetDir.resolve(Paths.get("testfile_hl"));
            target = hardLink.moveTo(target);
            int linkcount2 = Attributes.readBasicFileAttributes(path,
false).linkCount();
            System.out.println("linkcount1 " + linkcount1);
            System.out.println("linkcount2 " + linkcount2);
            boolean result = (linkcount1 == linkcount2);
            if (result) {
                System.out.println("BasicFileAttributs are same after
moving hardlink");
            } else {
                System.out.println("Basic File Atributes are not same
after moving hardlink");
            }
        } catch (Throwable e) {
            e.printStackTrace();
        } finally {
            try {
                path.delete(true);
                hardLink.delete(false);
                target.delete(true);
                targetDir.delete(true);
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}
</Code>
