Build nk2 Outlook from Contacts Address Book

Question

Clearing the nk2 cache is straightforward. However, I was wondering if anyone had had any success building a nk2 file with the contacts in the Contacts list. My original idea was to clear out the contacts that were not in my Address Book, so delete the nk2 file and then rebuild one from the Address book, or delete from the nk2 those that are not in my Address Book.

Essentially, does anyone know how to, in script or a nk2 editor, read the contents of the Address Book?

Thanks in advance.
