How to create a flow chart of folder, subfolder and contents?

I'm trying to create a flow chart of my product image library for a company that will be facilitating our online customer image library. I'd like to show the folders and subfolders visually so it will be easier for the vendor to understand it. I could create it in illustrator but I'm looking for an automated tool.



Does anyone know of an application that can accomplish this?



Thanks in advance.
