Do you sometimes get "Winmail.dat" files containing important documents? Winmail.dat Opener is a free app that allows you to open these files and view, save or share their contents.
This app is free of charge and fully functional, without the need for further in-app purchases.
The app requires only about 3mb space and no unnecessary permissions.
Your files are processed on your phone and not sent to any external servers. This ensures that your information stays private and the app will still work when you are offline.
The app is supported by unobtrusive ads -- no overlays, pop-ups or the like.
