Almost 90% of the winmail.dat files I receive in emails contain pictures. Finding an app which would enable me to open this type of file and view the pictures contained within, thrilled me!
Sadly, however, this app does NOT allow the user to be able to do this. The picture(s) comes through as an "untitled attachment" file, and according to the creator of this apps description, we are told that these types of files would not be able to be viewed. It is my own fault for buying this app without fully understanding its capabilities - but I did not know that a picture in a winmail.dat file would be called an "untitled attachment".
Further searching in the App Store, I found a more expensive app called "winmail.dat - Letter Opener". I bought that one and it worked great - allowing me to be able to view pictures, amongst other types of file types as well.
My intention of this review is to NOT belittle the creator of this app (Winmail File Viewer), as it does work with other types of files. Its just to point out to those looking for the ability to view pictures embedded in the dreaded winmail.dat file, that this app is NOT for you. Thank you.
