If you're looking for a simple way to remove duplicate contacts from a vCard (VCF) file, there are a few tools out there, but not all of them are easy to use. The OSTtoPSTAPP vCard Duplicate Remover is one choice that performs really effectively. Its especially meant to examine your VCF files and organized any repetitive contacts without compromising your data. I have personally found it really useful, particularly in relation to massive contact lists that grow disorganized over time. I would absolutely advise using this application if you have duplicate contacts and want something that really works without hassle.
