Preloading Multiple External SWF files

programming flash
1

hello-

this is how im trying to preload external swf files:

 
var Count = 5;
for (var i = 1; i<Count; i++) {
 var fileLoad= this.createEmptyMovieClip("fileLoad"+i, this.getNextHighestDepth());
 fileLoad.loadMovie("swf/page"+i+".swf");
 }

i am loading first four swf files from swf directory (page1.swf, page2.swf, page3.swf, page4.swf) - However, I WOULD LIKE THEM TO BE INVISIBLE WHEN THEY ARE PRELOADED TO THE STAGE… how should i do that… “fileLoad._visible = false;” does not work- please help!!!
