Prohibiting File Copying From Flash CD to Harddrive

I have created a small flash application. There are swf files, folders with xml files and the base exe file. The application has been burned onto a CD and will be replicated. The client is concerned that someone can take the CD, copy the files to a harddrive and then duplicate the CD themselves, possibly selling it.

How can a CD, with flash content be replicated and not allow files to be copied?

Any thoughts or help is appreciated. Thanks in advance.

Sorry but you can't prevent that... Any files on CD, or just about any other media for that matter, can be copied. That's just the nature of digital media I'm afraid - even "copy protected" discs such as console games are not that difficult to copy in reality.

Better to focus on what after sales service you give to a customer making them want to buy legit copies, rather than pirates!
