but I note that Windows 7, (and Vista), use Junction Points. these are like shortcuts to proper folders, eg Music, Photos, Documents, etc, but may be called My Music, My Photos, and so on. They are not really folders themselves but just point to the proper ones in Win 7.

They are there because older software still needs to install in the old fashioned, "My Documents" folders in XP etc. They are legacy components.

Junction points don't hold files themselves.

Perhaps this is what you are seeing?
