Several import options are available for new users who downloaded the address book software for the first time. Contact data can be imported from various popular software programs such as Mozilla Thunderbird, Microsoft Outlook, Windows Vista but also file formats such as vcards, ldif or xml.

The address book software will automatically recognize possible duplicate contact information and display a dialog to the user that proposes a few ways how to deal with the data including options to skip or edit.

Important features offered by Open Contacts include:

  • Unlimited data fields to store any contact info. Along with predefined fields, you may add unlimited data fields grouped by section.

  • Comprehensive Categories. You may click on a category to view contacts of the category, or right click to list contacts of subcategories recursively.
