Copy files from one folder to another on the same MyCloud

I am going to make some filename changes to a number of files on my MyCloud, but before I start i am going to make a copy of the folder(s) - just in case I mess things uo, I have started to copy the relevant folders, but it is take quite a lng time. I assume this is because the copy process is copying files from the MyCloud device to my laptop and then back to the MyCloud device, Is my assumtion correct, if so is there a way to speed this process>


Have you tried Copy and Paste?
