VCF files, also known as Virtual Contact Files, store contact information in a plain text format. They are often used to export and import contacts between different applications and devices. VCF files can contain various types of information, such as name, phone number, email address, and more.
To open a VCF file on a computer, you can use any text editor, such as Notepad or TextEdit. However, some email programs and contact management applications can also open and import VCF files.
