Hello,
I transferred the files from the Mini 3 Pro to my Android tablet using quick transfer, I can see them in the gallery of the DJI Fly app, and now I would like to copy the files on my external hard drive and on Google Photos.

But where the heck are the damn files, I can't find them in any folders of my tablet?!!

Hi there. Thank you for reaching out and we're sorry for the trouble that this has caused. The QuickTransfer feature allows you to download photos and videos directly to the mobile device, you may also upload them through social media platforms. If you want to copy the original files to your hard drive, kindly please remove the SD card and connect to perform the transfer via PC or Mac. You may also refer to the tutorial below about the QuickTransfer. Have a wonderful day ahead!
