1. Move/Copy file between folder.
for latest Firmware, using ES Explorer
you can do multiple move/copy by choosing cut/copy (choose multiple action first) press and hold you will see option.
change to target directory, you will see the UP arrow almost the button of screen click on it, it will scroll to see what files are waiting actions.
2. Move installed app to SD.
It means you need to move all of you current Library/App area and other workspace to SD.
You can prepare it by using Setting.
Seem to be good for sharing EE with others.
WARNING: it is no return point, you need to factory reset to change back to Internal Storage (and lost everything)
Does it help?
