My Book WD30200C032 Cannot see my files

I cannot see my files but I know they are there. When I right click on MyBook and view properties I can see memory used and memory left. So I know the files are there. What do I do so I can see them?

Check the link below for the steps to show hidden files.

I want to know the same things. I cant see any of the actual files on the my book essential…but i can see the space theyre taking up. I dont want to retrieve them, I just want to see them, and be able to use them to drag into a program.
