What is a CONTACTS file

CONTACTS files mostly belong to Contacts App. CONTACTS files store contact information such as names, phone numbers, and addresses. The internal structure varies, so the way the data is packaged influences how you open and view the file.

ZIP Format: One common type uses a ZIP container. These files are compressed archives that typically hold an address book for mobile devices like iOS or Android. They are often used by services like those linked with Google Contacts.

JSON Format: Another type uses JSON, a structured text format. This type holds a phone contacts list and is associated with applications such as Contacts+. More details can be found on the Contacts+ website.

UTF-16 (LE) Format: Some files store contact details as a text file encoded in UTF-16. This format supports international characters and yields an address book file that is editable with text editors.

PNG Format: A smaller group uses the PNG image format to hold digital phone contact lists. These files are used by apps like Samsung Contacts and may display the contact info as an image.

FilExt.com notes: The functionality of a CONTACTS file depends on its internal format. To open these files, use an archive extractor for ZIP, a text editor or JSON viewer for JSON/UTF-16, and an image viewer for PNG. This variation makes CONTACTS files flexible for backup, sharing, and restoring contact data.

How to open a CONTACTS file
