Probably this problem has already been discussed but…  
I’m working on a simple non-XML-based slide show where the container MC dynamically loads sequentially numbered files ([FONT=Lucida Console]01.swf, 02.swf, 03.swf,[/FONT] etc). As you may already be gathering, I want to write a little loop that returns [COLOR=RoyalBlue][FONT=Lucida Console]true[/FONT][/COLOR] if the file is there, e.g. if there’s only files, [FONT=Lucida Console]01.swf – 07.swf[/FONT] and the loop checks for [FONT=Lucida Console]08.swf[/FONT] and doesn’t find it, it returns false.  
BTW, in this particular case checking loader MC’s [COLOR=DeepSkyBlue][FONT=Lucida Console]\_width[/FONT][/COLOR] won’t work, so I need an alternative to that.

Thanks
