Managing contacts on Windows can become complicated when they are stored in different formats or applications. Many users keep contacts in Outlook, Excel, CSV files, or vCard files, and organizing them manually is not always easy. Using an Address Book Manager makes things much simpler because it allows you to maintain and manage contacts in a structured way. One tool I tried recently is TrustVare Contacts Manager. It works as a complete contact management solution and supports different contact file formats. It helped me organize my contacts and maintain them without losing any information. There is also a trial version available if you want to test how it works.
