In the world of technology, many users are facing the issue of duplicate vCard files. I suggest you try MacSonik vCard Duplicate Remover through which you can remove duplicate contacts, multiple files and folders. By the Duplicate Removal Parameters you can remove duplicates of VCF files based on parameters like First Name, Last Name, Mobile Number, and Email Address. The software comes with a Free Trial Version before purchasing the premium license. Its demo version can remove duplicate contacts from 10 VCF files and save only 25 original contacts per VCF.
