Saving Additional Files Added to Folder after archiving CD

[Art5]

Hello,
I'm wonder if someone could tell me how to accomplish this?
I've backed up a Folder to CD or DVD.
Since the Backup, I've added new files to the Folder.
How can I?
1. Compare the Folder to the Backup CD and Copy the newer files
to a new folder.
or Delete the Files that are identical on the Folder and Cd.

I tried comparing under the sychronizing command and can find the unequal files. But can't copy them
anywhere. I can't sychronize to a CD of course.
I've tried right clicking and selecting them all for copying.
But when I swich directories from the CD as the copy to, I cannot paste.
Thanks for any help

When you use Synchronize option and find the unequal files you can copy the files where you want.
Just press "Synchronize" button and... change the destination folder then in the box with path.
