Can I add further content to the CDs or DVDs once they have been burnt?
Yes. If you let us know that you wish to do so prior to production of the discs then we will not ‘finalize’ or ‘finish’ the CDs or DVDs. This will then allow you to add further files to the discs (as long as there is enough space left on the discs) at any point in the future.
As standard all of our CDs and DVDs are finalized during production to stop anyone from tampering with the discs once they have been distributed.
Finalizing a disc adds a small amount of further information to the disc stating how many tracks are on the disc and where it ends. This information is not important for data CDs if you just have PDFs, PowerPoint files or your website on the discs for example, but if they are CD-A audio CDs (for playing in standard audio CD players) then it is important to add this information and to finalize the discs, otherwise they will almost certainly not work properly in audio CD players or in read-only CD/DVD drives.
