This is not a very good approach, since it's extremely unportable! ;)
You should basically _not_ write to files! And File() is not the best
option anyway, since this is even more unportable. (Use URLs, I believe,
as your File(), and open streams on them. This because e.g. TC4 uses some
JNDI to handle all file requests, and they truly mess with your
file-"upload" possibilities..)
