Don`t use MAC`s, but *.SRT is on PC open with Notepad, Word or any text editor...
Its the same file used to add subtitles on videos/Series....

It contains synchronized flight data which will play as a subtitle over your video during playback if you enable subtitles in your video player, as long as both files are in the same directory. It's a video sidecar file with the flight data. Keep them together. If you don't want it, turn off video captions in the DJI GO app.
