The number (16206 here) is probably an index into an internal table
which contains all the shared files. This is actually a Good Thing
because it means that you can only download files that are in the table
in the first place. If implemented correctly it makes directory
traversal
attacks impossible.

Another thing that bothers me about KaZaA is that it downloads its
updates
not from a central server but from other peers on the network. If the
client
doesn't perform any integrity checks on the file it would be trivial to
serve a trojan as update which would be automatically executed after the
users permission to update KaZaA.
