But, there _is_ a pattern.  (Though there is only one mixed-case name there, 
so it's impossible to say if this pattern applies to such files.  What 
happens with a file named "FooBar"?)

I immediately see why some (all lowercase) filenames are converted to all 
uppercase, while others aren't.  What do all the all-uppercase names have in 
common that distinguish them from those that remain all lowercase?  (Hint: 
think MS-DOS.)
