Well, if you don't have any firewalls or protection programs up, then anybody could just access them when connected to your OS, but they'd have to do that on purpose. And I'm pretty sure you could do the opposite if you want, look at anything I have in the External or my cyberbrain that I don't have protected. But you'd ask before doing any of that, right?

But don't worry, if you don't want me to access anything, I can promise not to do so! I can just transfer the file and that would be it!
