What is a NCO file?

The .nco file extension is most commonly used by the Nero Backitup file archiving and backup software. The NCO files contain compressed backup files that have been created by the software. These files can be backed up to CD or DVD and allow the user to restore the files on their computer if the original file copies become corrupt or are accidentally deleted. In some instances these files are encrypted and password-protected for added file security.
