Hello, I am Vaibhav Verma, and I work as a software engineer at Sysinfo. The Sysinfo vCard Duplicate Remover tool quickly and accurately removes duplicate contacts from multiple vCard files or folders, using criteria like names, phone numbers, and email addresses to ensure precision. With a 100% success rate, you can trust that your contacts will be dedicated with ease. Plus, the tool supports all versions of VCF files, including vCard 2.1, 3.0, and 4.0. The tool ensures your data is safe and intact. It's also compatible with a range of Windows operating systems, from Windows 7 to Windows 11, so you can use it with confidence.
