I had a new computer built. They were to clone my C drive but encountered and error and simply installed a new Windows for me. I have the old C drive in the new tower. I have installed Thunderbird and the inbox automatically was loaded. Now I need to move my stored local folders and address book. So, I have a copy of the old drive, accessible in the new tower but no longer can launch Thunderbird on the old drive, so need to know how to move my local folders and address book to the new C drive.
