Winmail Opener is a small and simple utility that allows you to view and extract contents of. -encoded messages (infamous winmail.dat). That means if you receive winmail.dat on your e-mail, with Winmail Opener you can view the rich text message contents and attachments embedded into this file. You may receive winmail.dat files from the senders who are using Microsoft Outlook (97, 2000).

For instance, when the computer encounters a DOCX file, it will use Microsoft Word to open the file. DAT files are not as uniform as DOCX files, however; DAT files are data files, and the data can be anything from plain text to pictures.
