I always make sure I have everything on my PC before deleting from the SD card or source so I too use Copy versus Move.
I personally use right click method on everything and choose Copy Here as it relates to images from SD Card to PC. Many years ago I took a Windows course and the instructor kept pushing "use right click". I asked why when it requires two click of the mouse. His answer was "once you get used to it then you will never go back" and I found he was correct. The best reason was I always perform the task I wanted and rarely say "Oops".
The data is likely still available on the SD card using one of the recommended programs to recover the data. Don't take any more pictures before running the recovery process.
