thanks for being so fast, devnull...

i see what you mean with your first idea, but it's almost useless for me... but still, i can load the movies and unload them right after... but it will take forever, since they are numerous and quite big...

about your second idea, i was thinking about something like that: have an external .txt file with the name of the .swf (here it was called "hello") that contains only a variable that "proves" the existence of the .swf file... is that what you were thinking about?
