Help with Nero

[User Needs]

Is there any way to restrict access to only one folder when using Nero Burning ROM?

We have a cybercafe and don't allow access to the C: drive. But we also want to allow access to a shared burner. NeroNet will allow us to share this burner, but Nero Burning ROM will then give access to the C: drive. A bit of a dilemma!
Using,
Windows XP Pro sp2
And cybercafepro v4.5

Thanks for any and all help
