We all know that by default “My Documents” folder is located at C:\Documents and Settings\X\My Documents, where “X” is the name of the user. If there is not enough space in the system drive then one can move this folder to a different partition.
Firstly create a folder in a different drive.
Next assign proper permission.
Now open My Computer.
Right click on My Documents present on the left side menu and select properties.
Change the target folder path and Apply.
