Comments on Winmail.dat Opener for Android

★★★★★ Ed Mooy · Sep 21, 2021

Lately, any pictures in the attachment appear for a second, then are replaced with an !

★★★★★ Thiago Cordeiro · Aug 21, 2024

Lifesaver, thanks for this app! Really helpful!!!

★★★★★ Wolfgang Riss · Sep 6, 2025

Works well, so far. The only thing that feels superfluous is having to grant access rights for the same folder every time you save an attachment. As for ads, I'd rather pay for an ad-free premium version.

★★★★★ Mahmoud Saadi · Feb 16, 2022

Deserves 5 stars, Useful easy, works great.

★☆☆☆☆ Frankie Neuhoff · Mar 8, 2021

It didn't work! I still couldn't open the attachment!

★☆☆☆☆ illuzion · Apr 21, 2021

It clearly shows that the file type is .DAT type it still shows, it is not a .DAT type file. **PATHETIC APP**

★☆☆☆☆ Dru Greene · Feb 11, 2025

After I installed this app, I still get the message that there's no app on my phone to open the document I've downloaded
