I have a Kocaso MX780 Android 4.4.4. I have a 16GB sd card installed. I have ES File Explorer app installed I want to move photos from the Gallery to the SD card. If possible, I would like to set up subfolders on the card, such as "Disney_2016", "Sally's_wedding", etc., and move the photos to the appropriate folder. How do I move the files? I would like future photos to go automatically to the sd card. What camera apps allow me to do this? Finally, is there anywhere downloadable, written documentation for this and stuff like this? Thank you all in advance.
