You can change the information in the area and click "Move..." then "Apply", system will them create a folder in the area, move the data to the new area and reset the registry to point to the new default location. Once done you can simply click the "OK" box. Optionally after making the edits you can simply click "OK" and this window will disappear and the requested action will occur in the background. Your choice, I like confirmation so will usually monitor a process this important.
