TNEF's Enough allows Macs to read and extract files from Microsoft TNEF files. The files are usually received via email from Microsoft Exchange and Microsoft Outlook users. Standard e-mail programs will receive the TNEF file as an attachment named "winmail.dat."

The "winmail.dat" file can contain attachments, contact files (.vcf) or calendar files (.ics) as well as a rich text or HTML version of the email body. TNEF's Enough can open the "winmail.dat" file and allow you to extract the attachments.

Portlander freaking out ,

would have paid for this!

Drag and drop - that’s it! Thank you so much, I was ripping my hair out trying to open tax files from our fired accountant - really didn’t want to make that call to get them and now I don’t have to - thank you!!!!!!

Light-Tradet ,

Wow! Thank you!!

This was the first app for this application that said it was free and actually was free! I used it to open a pdf file sent from a windows PC and it worked perfectly. And no hidden charges! Thank you.

Al on the coast ,

Works perfectly

Every so often I get some .dat files from the unfortunate people who have to use PC's.
This app unzips the content and allows you to simply drag the contents wherever you like.
Fantastic - Thanks
