Navigation Between multiple SWF files

Question

ok so I'm still working on this project and it got literally huge... at least huge enough to consume all of my 3 GB RAM memory and crash my Adobe Flash CS4. Anyway, I decided to put the site on several swf's but the problem is that I've never done that before so I have no idea how to navigate between them.
Basically I have a main swf file, inside it there's an image (let's say its instance name is "projects_btn") that should take me to "Projects.swf", and I want to click on an "x" sign (its instance name is "xSign_btn") inside Projects.swf that would take me back to the main swf file "Bnaider2.swf".
Any suggestions? thanks in advance...

1. ok that link was very useful, thanks alot. project.swf is loading properly. But I donno what's going wrong, it just doesn't unload the project.swf when I click the xSign here's the code, maybe I've screwed something up:
//On the main timeline of the project.swf file:
xSign.addEventListener(MouseEvent.CLICK, xClickHandler);
function xClickHandler(e:MouseEvent):void
     dispatchEvent(new Event("backHome"));
// On the main time line of Bnaider.swf file:
projectsImg2.addEventListener(MouseEvent.CLICK, onProjectsClick);
function onProjectsClick(e:MouseEvent):void {
     var urlReq:URLRequest=new URLRequest("project.swf");
     var proLoader:Loader = new Loader();
     proLoader.load(urlReq);
     proLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, loaderHandler);
     function loaderHandler(e:Event):void {
          addChild(proLoader);
     function loaderCompleteHandler(event:Event) {
          (event.currentTarget.content as MovieClip).addEventListener("backHome",xClickHandler);
     function xClickHandler(event:Event):void {
          proLoader.unload();
2. the projects section of my site is divided into four swf's. First "project.swf" should load when I click on projectImg2 inside Bnaider.swf which is working fine so far (but doesn't unload once I click the xSign). Then I want "project2.swf" to load/run once I click on a button instantiated as "nextSwf" inside "project.swf". And on project2.swf as well, there's an xSign that once clicked  it should take me back to Bnaider.swf... and the same thing with the other two swf's. So... I donno, this is really getting too complicated for me, but if anyone could help I would really appreciate it cuz the whole project is due this Saturday and I've still got a few more things to work on as well... Thanks in advance...
