When cleaning up vCard files, one of the biggest concerns is accidentally merging contacts that are not actually duplicates. This usually happens when the comparison is based on limited information, like just the name. A safer approach is to use a tool like SysInfo vCard Duplicate Remover, which allows you to define multiple matching criteria such as email addresses, phone numbers, and full names. By doing this, the tool can accurately detect real duplicates and remove them without touching unique contacts. This method ensures your contact list stays both clean and reliable.
