So, are you able to open the context menu on the Mantis? Control M should do it. So in there you can find all these commands. So, when you're on the file you want to copy, or on the folder, hit Control + Enter to mark the item, To mark everything in that folder, Control A. Then you can press Control C for copy. Then, go to your SD Card, and press Control V. You can hit Control D to get to your list of drives. Sorry if you've tried all that and it didn't work.

Are you trying to transfer from the computer to the SD Card or from the Mantis to the SD Card?
