A folder could be created for each site that you are designing in the manner, to keep each site's files seperated and easily accessible and identifiable.

Ideas on Simplifying Coding for Preview, TESTING and LIVE Site
Navigate to the program's /Preview directory and create a new FOLDER to place all your CSS and JavaScripts in that will be used within your websites. We like to name it MASTERS and create a directory structure within that contains a seperate folder for each technology (CSS, Scripts, etc.) to make it easier to find items. Then, when referencing for imported CSS stylesheets and Scripts, you can use RELATIVE URL addresses, just as if it were on YOUR SERVER (which the site will be) and you will not have to re-code the site seperately for testing your styles and imports with WS 4.0, and again when the site is created and placed LIVE on your server. Copy the MASTERS folder to the server when updating pages of the site.
