Hi Terry
I am Dave, an Independent Advisor, I will help you with this . . .
Open Windows File Explorer
In the right hand pane, right click your Documents folder and choose Properties
Select the Location tab
In the Location box, type D:\Documents then click Apply and OK
When that move completes, do the same for Pictures, Videos and Music
Each time, you must provide a new folder location, for example, Pictures will go to D:\Pictures
If the above does not work for you, please provide a screenshot of any error you encounter . . .
