Removing/Exporting Images and PDFs from Research Section?

Hello.

I had thrown a lot of images and pdfs into the research section into multimple folders, along w/ notes etc. Now my scrivener file is so big that it takes forever to save. I figured it’s best to save all my images elsewhere but there’s no clear way to drag the image out or download it that I can see. I had to open the scrivener file’s contents and search through a hundred folders to find the files named “content” (later I figured I could search for content within the folder and drag them all out)–but this seems very cumbersome. Is there no easy way to export an image dragged into scrivener reserach? (some files are in the content area and some are in the notes area so I’m not sure if I got it all anyway)… thanks!
