No url yet to share - still trying to get it ready to publish

Simple questions for the calibre of folks out there.... I want to call a file in a subdir on my HD. Thereby, I can inspect slink and stuff before publishing. How can I make the menu access the HD files with the aI line?
This:
aI("text=WebSmith;url=http://www.softidiom.com/;");
obviously calls up a page from the web.
If I want to call pages from my own HD what does the syntax look like?
This:
aI("text=Weekend in Ulm;url=/www/fun/2003/ulm.html;");
is not working for me. FYI, the root dir is directly "above" /www/ e.g. d:/www/.... but the menu_data.js file in a separate subdir 2-3 levels "below" the /www/ directory.
BTW, before publishing the site I plan to use the find/replace tool to insert all the necessary http://... stuff in the aI line that will be necessary for the published version.
Thanks!
