You can delete address books that you no longer need or require, which is a good habit to get into as it keeps your address book lists free of clutter.
Deleting an address book also deletes the contacts in it but it doesn't remove those contacts from the 'All contacts' address book.
Steps to delete an address book
- Select Contacts from the navigation bar to display your address books.
- Use the checkboxes to the left of each address book to select ones you want to delete.
- Click on Delete, positioned next to 'More actions'.
You're then prompted to confirm this action.
Confirm by clicking on Delete.
