Open your Address book, click on all in the left hand side (or if you organize by groups you might want to select them one at a time and do this) and go to "File" > "Export Group vCard..." It'll export your addresses in vCard form.
I need the actual file. Because I had a backup of my computer. So the address cards are in some file on the backup. That is what I want to now.
thanks though do you know where the file is
