About .nnt Files
NNT files are plain text files used by the Eudora Address Book system. They carry the MIME type text/plain, which means their content is stored as simple text.
Their primary role is to maintain contact details for the Eudora email client. These files can be opened by basic text editors as well as Eudora itself.
- Purpose: Store and manage email contacts.
- Format: Plain text for easy reading and editing.
- Software: Openable with Eudora, Notepad, Notepad++, and similar applications.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
What is an .nnt file used for?
An .nnt file is a data file associated with the legacy email client Eudora, specifically used to store address book information. These files save contact details in a simple plain text format, making them readable by humans and compatible with various text editing tools.
How do I open an .nnt file on my computer?
Because .nnt files are plain text, you can open them with any standard text editor such as Microsoft Notepad, Apple TextEdit, or Notepad++. Simply right-click the file, select Open with, and choose your preferred text editor to view the contact data.
Can I import .nnt files into modern email clients like Outlook?
Modern clients like Microsoft Outlook or Mozilla Thunderbird usually do not support .nnt files natively. To move your contacts, you typically need to open the .nnt file in a text editor and manually convert the data into a CSV file, or use a third-party Eudora conversion tool.
What is the MIME type of an .nnt file?
The .nnt extension is associated with the MIME type text/plain. This standard classification ensures that operating systems treat the file as generic text. For more details on how text types are handled, you can visit mime-type.com.
Is it safe to edit an .nnt file manually?
Yes, you can edit these files using a text editor, but you must maintain the specific formatting structure if you intend to use the file with Eudora again. Altering the layout of the text might corrupt the address book entry within the Eudora application.
Why does my .nnt file look like a text document?
Since the underlying format is plain text, your operating system may assign a default text icon to the file. This behavior is dictated by the file's association with the text/plain MIME type configuration.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
