You do realize that clients can still "Show hidden files" in their Explorer window's options and see your files, yes? Assuming you're OK with that, then the files should copy over to CD with their "hidden" attribute in tact.

Did kaufmed's answer resolve this?

Not sure what you're really going for here, so it's hard to know what to recommend. You can't really hide files from users if they have access to the system. You might be able to do some fancy tricks likes store them into an encrypted zip file or something, but I don't know.

You could also use alternate data streams on ntfs and when burning to disk change them to UDF named streams, there will still be a file, but it will have zero bytes, with all the data in the alternate data stream.  The following code uses a library that can be found here

        private static void CreateFileStream()
        {
            string filePath = System.IO.Path.Combine(location, "MyFile.txt");
            System.IO.File.WriteAllText(filePath, "");
            System.IO.FileInfo fileInfo = new System.IO.FileInfo(filePath);
            var alternateStream = fileInfo.GetAlternateDataStream("Hidden").OpenWrite();
            byte[] byteMe = System.Text.ASCIIEncoding.ASCII.GetBytes("This is how the world ends, not with a bang, but with a whimper.");
            alternateStream.Write(byteMe, 0, byteMe.Length);
        }

        private static void ReadFileStream()
        {
            string filePath = System.IO.Path.Combine(location, "MyFile.txt");
            System.IO.FileInfo fileInfo = new System.IO.FileInfo(filePath);
            var alternateStream = fileInfo.GetAlternateDataStream("Hidden").OpenRead();
            byte[] byteMe = new byte[alternateStream.Length];
            alternateStream.Read(byteMe, 0, byteMe.Length);
            string msg = System.Text.ASCIIEncoding.ASCII.GetString(byteMe);
            Console.WriteLine(msg);
        }

Open in new window
