moving items out of research folder

I put a bunch of HTML pages and PDFs in the research folder in my Scrivener project, which I’d now like to move elsewhere (Papers 2) so I can organize them better. I can’t seem to be able to drag and drop, though. Is there an easy way to do this somehow?

Just select them and use File > Export > Files…
All the best,
Keith

of course! thank you!
