[rox-users] How do I enter a URI to ROX-Filer?

[Mike H. <mik...@an...>]

On the wiki MIME-Editor page (and similar for other apps) it says:
Zero Install <http://rox.sourceforge.net/phpwiki/index.php/ZeroInstall> 
users can simply open the directory 
*/uri/0install/rox.sourceforge.net/apps/*
in ROX-Filer <http://rox.sourceforge.net/phpwiki/index.php/ROX-Filer>, 
and run...
So how do I enter this?  I've tried the Goto: and the text appears in 
red and
it fails to do anything on pressing return.

I've tried to get AddApp and ROX-Session but they fail:
Can't find all required implementations:
- <Interface http://rox.sourceforge.net/2005/interfaces/AddApp> -> None
Can't find all required implementations:
- <Interface http://rox.sourceforge.net/2005/interfaces/ROX-Session> -> None
Can't find all required implementations:

I understand RISC OS intimately but I'm new to Linux (in a desktop sense)
and I'm struggling to get my head around the concepts in ROX.
Please help.
