CPU is cheap, disk bandwidth is expensive. Reading a .zip archive's file 
listings might actually be faster than reading a real directory, since 
the data might all be in the same page on-disk.

.zip files keep a signature at the end of the archive, which means you 
can append it to your .exe and PhysicsFS will treat it as a .zip file.
