Winmail Opener Review


Winmail Opener is a small and simple utility that allows you to view and extract contents of TNEF-encoded files (infamous winmail.dat). Winmail Opener can decode and show RTF message text and all embedded attachments, has full drag-and-drop support and supports command line mode for batch decoding. Winmail has a traditional Windows look and feel to it with drop-down menus. It also has full Windows drag-and-drop capabilities so it is easy to move text and attachments from an e-mail to a document or other location. Text is displayed in a center window with a scroll bar with attachments in a sidebar window.
