Frustration, not sarcasm . New computer is in the top 20 new thread questions
The first thing I do with new SW is read the FAQ
The Second thing is explore all menus and read the tooltips (and hope I remember the high points)
If you copy the Library folders over INTACT, they are good
If you copy the configuration folder INTACT,all your plugins will be there and user settings

repeat for each

You can keep your libraries anyplace (local drive) that you have FULL rights.
The default place is for a simple install
