Possibly a daft question, but how an earth do you put a password on to cd I'm about to burn?
Basically I need to send a cd out with scan data on to a customer but i want to put a password on for them to access it.

I tried to find software off download.com but that seemed to corrupt my CD drivers.

Any help appreciated

Thanks all, managed to zip the files and add a password.

I'm sure in the olden days (XP) it used to be easier than this.
