Unzip e-mail attachment "winmail.dat" or "*.dat

Sometimes you receive emails with an attachment in .dat file format. You cannot open this attachment directly, it must be unzipped first. The following procedure is recommended:

• First check if the mail is spam, if it is, ignore it.
• If the mail is wanted, save the attachment on the computer, e.g. in the directory ~/Desktop.
• Open a console (or a terminal). Enter the following commands:cd ~/Desktop tnef -f winmail.dat -C./

This unpacks the file winmail.dat in the directory ~/Desktop. If you have saved the file in a different directory, change the commands accordingly. If this procedure does not lead to success, please contact the admins.
