Winmaildat Opener

By Tobias Reinhardt

Open iTunes to buy and download apps.


Winmail.dat Opener is a free app to open those common 'winmail.dat' attachments. This app is free of charge and fully functional, giving you access to the files without any need for further in-app purchases. The optional in-app-purchase will remove ads.

Our app registers as a handler for .dat files. It is launched when you tap to open the "winmail.dat" attachment, enabling you to see a list of its contents. You can then preview, resend or print the contained files or save them to an album.

This app will extract the winmail.dat on your phone or tablet, it does not require an Internet connection for this process. As our app is ad-supported, it has to ask for permission to access the Internet, despite the fact that the actual extraction process does not require an Internet connection.

Kindly note that not every file ending with .dat is a winmail.dat file. So, before submitting a one star review stating that our service didn’t work, please ensure that your file is indeed a winmail.dat file and not one of a hundred different file types with a .dat extension.

Does exactly what it says!

Very easy to use and no bait and switch. Just download, open your email, tap the win.dat file, and choose this app to open. After it opens thru this app it gives you an option to save etc. Very happy I can now see my photos I sent from my desktop!

Life saver on .dat

Thank you guys for this it's awesome and very helpful

Well done! Works great.

I received the notorious winmail.dat attachment. I though by 2016 this wouldn't be a concern but, alas, Outlook is still the obnoxious and self-centered mail client it's always been.

I found this app through a search in the App Store and am pleased to see it does exactly what I needed. I appreciate the option to share the contents of winmail.dat while selectively removing the content I don't want. For example, I received a set of photos and extracted to forward only those without forwarding the mail attachment.
