Better choices exist but the differences are minor

Right-click (Open With) is a much needed feature.

Works fine so far

Am now able to open winmail.dat files by clicking Open on the attachment in the email (Outlook 2011 Mac). Drag and drop from the email doesn’t seem to work but DnD from Finder does work. Rating a 5 for now as purchase, installation and use went quickly and without any problems.

version 2.2 works on my MacPro

I am using Winmail DAT Viewer version 2.2 on a MacPro. My office at work continues to send me attachments generated in Outlook which won’t open on my Mac. This program works perfectly for me every time. I don’t understand why some of the other reviewers have a problem. I have a 2008 MacPro running El Capitan, but it also worked for me with the previous OS versions.

Bunch of .dat files, says all contain no data

It says all of them have no message body, and no attachments. File sizes from a couple hundred bytes to severl megabytes. Others have opened these files. Doesnt seem right to pay good money to find out the program wont work.

Works as described

Have some clients who send me photos for bidding purposes, on construction jobs. Just couldn’t open them, until Winmail DAT Viewer came along. Always there, always works. Thanks.

Easy to use

Love this little app that converts win.dat files to something I can open on my Mac. Only problem is that if you save the win.dat file to your hard drive, be sure to change the name of the file so that you don’t copy over previous win.dat files if you save them to the same location.
