Change working directory

My main movie calls [COLOR=crimson]loadMovieNum(“projects/index.swf”, 1);[/COLOR] . Therein, the movie index.swf calls [COLOR=crimson]loadText.load(“projects/projects.html”);[/COLOR].

Is there a way to change the working directory so that index.swf can simply call [COLOR=crimson]projects.html[/COLOR], without referencing the [COLOR=crimson]projects[/COLOR] directory? This is particularly useful bc the text file calls a number of links.
