Great App

Does exactly what it says!

Note: to add double-click support,
1) find a winMail.dat file in the Finder,
2) Get Info (Cmd-I)
3) In Open With, select TNEF’s Enough (or Other>Applications>Utilities>TNEF’s Enough
4) Hit Change All

Now any .DAT file you double-click (even in Mail) should launch the program to save your files.
