delete any files that have names or file names like 927438724723 because they are viruses.
That's a wild statement.
Fourthed, that's definately not wise. My camera names photos by the dates they were captured, so you end up with names like that.

But seriously, even if you do come across a file you think contains a virus, the most important parts of a virus will be far more hidden inside the computer system (I'm talking about the kind you need to use DOS to get rid of), the best thing you can do is leave the removal process to your virus scanner.
Also, I agree with Ben. F1 and Troubleshooting ftw.

You got all the box etc. with the Zen, right? So it should include firmware and software to make syncing very easy,
install and use that. If you can't get ahold of it,
get it here.
