This is not a directory, but under this registry keys there are several named entries (so called "values") which contain the directory names used by Explorer for different purposes. If you want, you can change them.
Just run REGEDIT.EXT and navigate to this key using the menu on left. In right pane, click on each value and manually change it. Be extra careful! This is Explorer! Don't screw up your critical data!
This won't touch original directories and its content. Now, do you need to move the content of these directories as well? You can do it, possibly using administrator account. Again, be careful. In the transition, just in case, I would not use Explorer. Use something like Total Commander, highly recommended (I pay just $46 per user for license with unlimited life-time support of this shareware, but unlimited trial period is also available. It also has an ability to "peck down" (this is how we call it) the full file or directory name into command line using Ctrl+Shift+Enter, which is pretty important because this way you will not do a dangerous name misspell.)
You can also write some code which will do this migration programmatically, using my solution for your previous question, see
Moving A File From One Directory[

Be careful. Just in case, make sure to reboot your system after this daring activity. :-)
May I know the ultimate goal of this weird alteration? :-)
