title: Flash, accessing totalBytes before actually loading the file
body: <p>Im looking for a simple way to find the file sizes of the files i planning on loading without loading them yet. I'm basically making a batch of files that needs to be loaded and it would be very useful if I could determine on beforehand how big the total load is going to be.</p>
  
  <p>the Loader object in flash has a totalBytes property, but that will only return a value when you are already loading a file.</p>
