How are the contacts stored @SailfishOS

Hi,

I have a problem with my contacts in my Jolla phone. I imported everything twice and have now over 400 contacts which I want to clear at once. Because there is no possibility in the gui to do so it would be cool if any one can say where they are stored and if they can manipulated at cli.

There might be more contact.db* files in that dir. I guess it's best to clear all three of them. I did, no ill effects noted.
To be safe, rename them, so you can restore them later if needed.
