After the data has been written to the disc, Nero ejects the disc and reloads it. After this, all the files in the compilation are compared and Nero checks whether the files have been written correctly. In multisession compilations, Nero checks only those files which were written during the most recent burning process and ignores all other files. At the end of the check, Nero displays a summary. This contains the information from the checking process: the number of identical files, the number of different files and the number of files which could not be accessed.
Caution: The Verify function can only be used with ISO9660 compilations.
