On windows, assuming it was using FindFirstFile or similar you would get  
alphabetical order on some platforms/file systems and FAT table order on  
others.  I imagine linux and associated platforms have similar behaviour.

To get a sorted list someone has to load all the entries and sort them.  I  
doubt the file system is going to do it, so either the library routine  
would have to, or you're going to have to.  As most file systems and  
libraries should take the most efficient approach first and foremost it's  
likely you're going to have to do it yourself.
