Creating "Extra Files" in a Session referenced in the Webinar Organizing with Sessions at around the 19 minute mark.

I followed instructions for importing into a Session.  I want to create extra files under the Capture Folder in System Files.  I created an extra file called Look 1.  Now I want to drag and drop images from the imported images into Look 1 but I don't know how to view them.  When I go to my Capture Folder under Session Folders I get screen messages that there are no Images in the Collection. 

How do I see the Images to choose the ones I want to put into my various "Extra Folders."
