This is the software publisher's description.

Simple utility for personal use designed as an add-on solution for Microsoft Outlook. It allows you to easily import, export, and convert while exporting your Outlook Contacts and Calendar events information from/to vCard (*.vcf), vCalendar (*.vcs) or iCalendar (*.ics) format files.

With vSync convert selected or all of your items to vCard, iCard, iCalendar (iCal), or vCalendar file format. This file is so portable and compressible, that you can easily send the whole folder to anyone (4000 contacts in a zipped Vcard file is less than 100Kb).

Whether you have iPod, cell phone, Palm, use Lotus Notes, - vSync for Outlook is your best friend. You can even sync Calendar and Contacts with your friends and coworkers or between two or more PCs. The vSync add-in for Microsoft Outlook is our vCard Wizard successor. With advanced filters and vCalendar support, this product is a real timesaver.
