The TNEF File Viewer is an application for TNEF mail attachments.

## Introduction

The TNEF File Viewer allows to handle easily mail attachments using the TNEF format. Those attachments are usually found in mails coming from Microsoft® mail servers and embed the mail properties as well as the actual attachments.

An attachment in TNEF format is most often named `winmail.dat` or `win.dat`.

This utility program allows to perform various operations on those attachments:

- View/open attachments with associated applications.

- Extract actual attachments

- View message properties (TNEF/MAPI)

- View/extract message formatted text (in RTF format)

KMail automatically shows the content of a TNEF attachment. You can open or save the attachments using the actions in the context menu.
