Clicking on the above link should automatically load the Greasemonkey dialog
box to install the script. If not, save the script to your desktop,
drag-and-drop to your browser with Greasemonkey running, and it should
install.
Once installed, browse to your local XBOX with
something like:
http://xbox/xbmcCmds/xbmcHttp?command=GetShares¶meter=files
You can traverse directories, and even view text files. Can be useful to find out why the FTP server isn't working (eg "FileZilla Server.xml" file is empty).
Yeah, the doco is crap - volunteers welcome. Read the source!
