How to change my Documents folder sefault location path

The My Documents folder is a special folder that is attached to each
user account as the default save location for many types of file. Normally
this is located in "C:\Users\\Documents", but you may wish to
change this path to another directory or drive.
Changing and moving “Documents”(Win 7), “Documents” (Vista) or
“My Documents” (XP) to another folder on different hard drive or partition has advantage of keeping the system partition clean and reduce the risk of
running out of disk space. Beside, by placing and storing all personal or
business documents, ideas, notes, files in My Documents folder that is on
another separate drive or partition, users no need to worry about copy and
backup the data if there is a need to format and reinstall the Windows,
which may cause lost of all date stored in the My Documents in default
location.
