I presume that because your files can be readily browsed that you don't have a firewall and, as such, you expect every P2P user to do away with their firewalls as well.
This is all well and good if all you use your computer for is to play games and run your P2P apps. You don't mind if your PC is hacked, virus and worm infected or that the criminal gangs on the Internet turn your PC into a botnet and make it part of their criminal activities, e.g. DOS attacks, distribute illegal porn, etc. Worse still, plant spyware on your PC in an effort to steal your bank account and credit card details.
After all, because you don't have anything on your PC worth stealing then that's why you don't need a firewall.
You know, it's a pity that the rest of us can't be as care free as you are.
