By default, Apple Address Book exports multiple contacts to a single file (if you drag and drop the contacts). However, by holding the option key while dragging and dropping, individual VCF files for the contacts will be created.
It doesn't work!
Clicked on the exported card, the address book opens on the different person's info. Tried on the different card and the same thing again. I don't need this to open the address book. I really don't know what so good with this.
Maybe the developer should fix it.
