NTFS Junctions

From EggeWiki

NTFS 3.0 Junctions most closely represent **hard links**, and can only be created on directories. Junctions, like hard links, can only referrer to items on the same volume.

Additionally, NTFS allows one to mount other volumes as directories in a file system. This is similar to a symbolic link. The folder will exist if the other volume is not available, but you will receive an error if you attempt to access it in this state.

I haven't found any worthwhile use for junctions. I have used mounting other volumes. I have a USB key which I like to mount at C:\usb. This avoids me having to worry about what random letter it gets assigned to when I plug it into my Windows XP system.
