How do I access exported images?

How do I access the exported file of the design? Can you explain the process of exporting images and where they go? It says created PDF's will be store in https://www.flashionstatement.com/wp-content/fancy_products_orders/pdfs  but I don't know how to access those server folders?

Under orders - Export- I have tried to hit create and nothing happens so I don't know where the image goes and I am looking for an easy way to access it. Seems kind of dumb!

There has to be an easier way to export the image otherwise how do people use this thing?
