I have a Mavic Air 2.  How do I upload the onboard memory onto my PC?  Thanks!

Connect the drone to the PC via USB cable and turn the drone on.  

Hi there. Thank you for reaching out. DAFlys is correct in his response above. You may use a USB communication cable to connect your unit to your PC and from there you can check the internal storage of the unit. Should you have other inquiries, please don't hesitate to reach us. Have a nice day ahead!
