to create anntfs junction

Question

How can I create ntfs junction poin in windows xp

Answer 1

Is your definition of junction point a directory that is hardlinked to another one?

if so it is simple

mklink /J

After this there is no distinction between the directories. They have the same MFT_REF ( from http://en.wikipedia.org/wiki/NTFS_symbolic_link )

fsutil can also be helpful to query reparsepoints and make hardlinks.

If you wanted to know how to programmatically do this, you can us NTFS storage driver IOCTL calls on the volume handle. But it would be easier to just call mklink.

Be advised that you have to have write and modify priviledges for the target directory.
