I haven't searched the previous threads (sorry)

I have about 200 folders of Author names in the format:-
Surname, FirstName or Surname, Initial(s) or Surname, FirstName Initial(s)
Can I rename the above to:-
FirstName Surname or Initial(s) Surname or FirstName Initial(s) Surname
?
In other words - one surname string followed by a comma then FirstName and/or Initials. In all cases I want to lose the comma and put the FirstName and/or Initials in front.
