What's the best way to handle style sheet links that RSD automatically adds to page? I have my style sheets located in /css, and the link written by RSD is href="css/..." So if the page is not located in the root of my site, the style sheet links are broken.

If RSD wrote the links as href="/css/..." that would solve my problem.

I'm not following you. RSD will generate the proper structure for it's own css so leave it alone.

AFAIK, RSD does not support putting files in sub-folders.

I dont understand what you mean. Of course you can have subfolders. We are having problems understanding what you are trying to accomplish?

In the Pages manager, I've got Index.html which goes in the root. I'd like to have another Index.html that goes in /demo.

As a work-around, I added a page Demo.html that I rename after exporting the project.

How do you define your site's folder structure in RSD?

For that you cannot do. As far as I know all your pages will be in the root. You can create folder structures for your images though.
