Folder Dropdown for Saving Edited File outside Current Path

When I go to save an edited image to a location different from where the image was edited, the prompt goes only to the top-level folder of the selected drive. Would  one of you please show me how to dig deeper into the folder tree [if possible], in order to navigate to the desired location to save the altered file. I cannot imagine that Adobe does not offer this option, but if in fact it does not exist, I would urge Adobe to place it high on the queue for the next update.

Best,
