When you burn a data disc in CyberLink Power2Go, you can create a multisession disc that lets you burn additional content to a disc that is not full. CyberLink Power2Go creates a multisession disc whenever you burn a CD, DVD or Blu-ray Disc* and choose not to close the disc.
Note: * optional feature in CyberLink Power2Go. Check the readme file for detailed versioning information.
With multisession discs you can continue to add content to a multisession disc until the disc is full or closed, at which point you can no longer add any further data.
