/mnt/us/... <<-- You can only see this branch of the entire file system tree over USB.
This is the topmost visible level of USB storage.
If the Kindle system allowed you to access anything above /mnt/us/ or along side of it, there would be no need to jail break the device.
Note: I had to add the .bin extension to tree to keep the attachment manager happy.
It didn't hurt it and can be removed if desired.
This version of tree will run on any touch screen Kindle.
