I think you may be best using host-based scanning tools to get a full directory listings. I have in the past written many snippets of code that would traverse an infinitely deep directory tree, it's not too tricky.
On the command line, use "priv set advanced" to go into advanced mode, then use "inodepath help" to get a full listing of the command options. To be honest, I've not used inodepath for anything before, but it may be the right thing to help you out, I'm not sure.
You can also use "ls" in advanced mode, but again this is just single volume levels.
There is a way of getting a full directory listing, but I must warn you that this is very unsupported, and so I won't post it on the forums.
