@ Papiosaur - Wow ! - that's a neat trick / keyboard shortcut that I didn't know about until now.

I'd been selecting/copying/pasting the files to do that previously, but selecting file(s) and then pressing 'Alt', and dragging the file(s) to wherever you want them to be - on the same partition - is an even neater way of doing the same thing, so thanks for that little 'gem'.
