I am attempting to access the .DAT files from my Phantom 3 Pro.   I go through the app, enable flight data mode, and plug in the drone to my PC.  But when I explore the SD card, there are no .DAT files.  The only folder stucture is DCIM>100MEDIA>and then I have the video files and .SRT files.  

Am I doing something wrong?  I have a 128GB Lexar High Performance 633x microSDXC UHS-I card in the Phantom.  

You're plugging into the wrong port on the P3.... I bet you one upgrade that you've plugged into the camera...
The correct port to get access to the MC Flight Data is the micro usb port in the center of the P3 ABOVE the camera and BELOW the Gold Label that reads "Processional" that has the little plastic/rubber protector over it...

100% correct, I thought they were identical.  I will retry and update.  Thanks!
