Topic: Unable to see files in downloads directory

I need to move a set of pdfs and jpgs that were uploaded with Ruby on Rails to the downloads directory with my ftp client. I cannot see the individual pdfs and images. I can only see the folders inside the downloads directory. I can see the folders size in my ftp client but when I click on the folders there is nothing inside. How or what do I need to access the individual pdfs and jpgs?
