Well on Windows it does move if it is on the same disk and copy if it is on a different disk like from ab internal disk to an external drive. This can be changed by holding down keys during the drag and drop. Ctrl for copy and Alt for move. With all that said, I quite liked the option to choose what you want when drag and drop and I will change it back.
It is not hard. You just have to change it in the Settings, sorry in the Control Panel or was it in Registry. /s
