Fast and Easy - After getting a .dat file in the mail. I couldn’t figure out how to open it. I searched, and searched, and searched and couldn’t figure it out until I purchased and downloaded this app. It automatically installed and I double clicked on the .dat file and BOOM! it was opened. Thanks.

Garbage - Does not work. I opened a winmail.dat file from within Mail; it does nothing. I saved the winmail.dat to the desktop and try to open it from this app; it does nothing. Absolutely nothing - no error dialog, no window opens, nothing. Garbage.
