- Simply choose where to put the content

1 - Why doesn’t this app work for me?
Make sure it is a winmail.dat file that you are trying to open with this app!

a) Files such as just a .dat (not winmail.dat) are special data files (hence the name!), and only the software which created them can open them. They can’t be opened using this app.
b) A .wmv file is NOT a winmail.dat file, even though it looks similar! It’s a ‘Windows Media Video’ file which can’t be opened with this app.
c) An ‘Untitled Attachment’ or a ‘MIME’ file or an ‘.eml’ file is NOT a winmail.dat file, and this app should not be used to open this type of file.

2 - How do I open / view / edit the files which are contained inside my winmail.dat file?
This app will ONLY open the winmail.dat attachment, but for files contained inside you will need their own apps.
The Winmail File Viewer app is a simple app to open winmail.dat (TNEF encoded) files, so please don’t expect it to do anything more.

Was good

When I first downloaded this app, I loved it. Then, it stopped working correctly, so I updated it. It still didn’t work. I decided to give it another shot today, and it told me that I had to pay for any more use. I found a different way to open my file and will most likely delete this app.

Same here. Works sometimes but not other times. Not reliable. Always goes to wanting money.
