IF you either copied or moved it to the MSD card on your device, it would always be there for you to "play with".
You should always move/copy your vids and images from the DJI directory to a folder on the SD card in your device.
Remember, these are "low res" images and vids. The true Hi Res stuff is on the card in the AC. You should always move/copy them to someplace safe, like on your home pc/hard drive.
