A junction is a link.
So a folder can be pointed to a different path.
Where this helps would be programs that try to access the old paths say to the profile paths.
So a program tries to go to C:\Documents and Settings. On XP this is fine but In Vista and 7 it is in a new area. So by having a junction (Windows has this one by default) and point it to the new path the old program will still work fine

C:\\Documents and Settings
Type is JUNCTION
Final Destination:
C:\Users
The file you attached shows all normal junction points.
It didnt list the ... folder on the C: drive.
Some installed program has to of created it. Windows doesn't create that one by default.
