Does anyone know what address books are supported by the Skype import wizard (Skype --> Contacts --> Import Contacts...) of Skype 2.0 for Windows?

I need a complete list of the address book types that will be searched for on your PC's (Windows only) hard drive. I know Microsoft Outlook is one of them, but what are all the others?

Outlook Express is another one, and the address book of Opera another one (if i remember).
There is a fourth one (perhaps more), but i don't remember which!

In some past versions it were like "separate applications" that you could delete. And there were 4 like this.
