I encountered a similar issue when trying to locate and download the cached files from the DJI RC2 controller.
I first tried to access the cashed files with my MacBook Pro M2 2023 running OS Ventura 13.3. However, the RC2 controller was not being recognized, and Android File Transfer failed to detect the controller.
Here's a solution that worked for me: (Using a windows 11 PC or laptop)
1. Turn on the RC2 controller.
2. Connect the RC2 to a Windows PC (I was using Windows 11) using a USB-C to USB-C cable.
3. The RC2 controller should appear in the Explorer window as "DJI RC 2."
4. Click on "DJI RC 2" and navigate to the following path:
This PC\DJI RC 2\Internal shared storage\Android\data\dji.go.v5\files\MediaCaches
You should now see your cached files and be able to copy them to another location on your PC. This method allowed me to successfully transfer files from the RC2 controller to my Windows PC.
Bonus: The files for the favorites album are here:
Click on "DJI RC 2" and navigate to the following path:
This PC\DJI RC 2\Internal shared storage\DCIM\DJI Album
Nice to have this as a backup plan just in case you lose your drone but need to recover some of the footage, even if its super low resolution.
*** NOTE: The above procedure only works if you have enabled "Cache When Reorcding" on the drone.
To check and or set this:
1. Turn on the RC2 controller
2. Turn on the drone (
Air 3 in this example)and connect to the controller
3. press the three dots in the upper right to get to the settings menu
4. go to the camera settings
5. scroll down to find " Cache When Recording". This had to be enabled or there are no cache files for you to view on the controller.
