Adobe Draw & Sketch Folders in Fresco

just wondering if the Adobe Draw & Adobe Sketch Folders from the old apps which are in my Fresco Documents take up space?, (i also recently converted the files via creative cloud suggestion to fresco too) 

and if they do, if i delete the folders will they also be deleted from creative cloud?, i ofcourse want to keep them, but i don't actually tend to open my old drawings in fresco. cheers.
