Directory Symbolic Link or Junction

[hoak]

Which of these is more appropriate when linking directories locally across different volumes and/or partitions? Both seem to work virtually identically, and from the information I've been able to find the differences are low level and quite technical. So say I have a boot VHD on an NTFS partition (I actually do) and want to use a 'Directory Symbolic Link' or 'Junction' to offer access to an application on the main NTFS partition, again both work, and appear to do so identically, but is one method (mklink /d vs /j) better then the other in this example?
