This last bit worries me.  I don't see how that would be possible unless 
some sort
of marker was placed between the n'th and (n+1)'th file.  But then, it'd 
cause some
sort of horrible sound when you played the file... if indeed you ever 
intend to play
such a file...

Why would you do this?

If you just want the binary content merged into one long file, surely a 
normal file
copy/append would do?  Or you could zip the set of files into one file.
