What is a .NNT file?

The .NNT file extension is associated with a type of file known as a Eudora Address Book File. This kind of file is specifically created and utilized by Eudora, which is a program designed to manage emails. Inside a .NNT file, you can find a list of contacts. This list includes details such as the contact's full name, any nicknames they might go by, and their email addresses. These files are essential for keeping track of all the people you may need to send emails to or receive emails from while using Eudora.

To open a .NNT file, you would need to use the Eudora email client software, which is developed by QUALCOMM. This software knows how to read the .NNT file and display the contact information stored inside it in a way that's easy to understand and use.

It's important to note that .NNT files are usually found in a specific folder on your computer named "EUDORA," and they often come along with another type of file known as .TOC files, which also play a role in how Eudora functions.

However, it's worth mentioning that Eudora, the email client capable of opening .NNT files, is no longer being actively developed. This means that there are no new updates or versions of Eudora being released, which could potentially affect its compatibility with newer operating systems or technologies in the future. Despite this, if you have Eudora installed on your computer, you should still be able to open and use .NNT files without any issues.
