App Profile: Winmaildat Opener

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.
