Posted by on Jan 3, 2013 in Apple, Facebook Featured Posts | 0 comments

If you use an Apple Macintosh and receive emails from Outlook users or Microsoft Exchange users they may include attachments that are labelled winmail.dat. This file includes the RTF version of the email and any attachments, making it a bit difficult to open and access.

To access these you can do so using Josh Jacobs fantastically free tool called TNEF’s Enough.

Open WINMAIL.DAT by Installing TNEF’s Enough

Download

If your browser hasn’t opened it, you will have a .DMG file to double click to open. The DMG will open to a disk mounted in the Finder.

Copy to Applications directory

Simply drag it to your Applications directory. You might be prompted by your system for an administrator password.

Launch as needed or keep in Dock

Most users just open the app as needed. If winmail.dat files are a chronic problem for you, you can keep the app in your doc and drag winmail.dat files to it.

How To Use TNEF’s Enough to open WINMAIL.DAT Files

Launch

If you keep TNEF’s Enough in the Applications folder, just click to launch. Or store in the Dock if you get frequent winmail.dat files.

Open WINMAIL.DAT File

TNEF’s Enough opens winmail.dat files to show you what’s inside them. Assuming you have the winmail.dat file in an email, here are a couple ways to open it:

  • Save the file out of your email program. Choose Open… from TNEF’s Enough File menu and locate the file.
  • Save the file out of your email program. Drag the file to the TNEF’s Enough icon in the Dock.
  • Simply drag the attachment from your email program to the TNEF’s Enough icon in the Dock.

Export WINMAIL.DAT Files

TNEF’s Enough will then show you a window representing the TNEF file. The content is similar to an email message showing the typical From and Subject fields along with sent date, message body and attached files.

There are several ways to get the files out of the winmail.dat file:

  • Select one or more files and select Export… from the File menu.
  • Choose Export All… from the File menu to get all the files.
  • Select one of more files and drag then to Finder.
