Z520a connectivity

i'm navigating my z520a using SE PC suite but it doesn't seem like i
can find all the files/apps on the phone. i really like the message
alert tone #4 and want to use that as my ringtone...i just can't get to
that file to copy it into the correct directory. can anyone tell me if
this is possible? if so, how? if not, do you know where i could find
that tone....its not on SE ringtone download page.


thanks.
