How do you free up space on a computers cd and dvd drive?
An empty optical drive has no space. If it has a blank disk in it you can burn files to it to save them. Once files are burned to the disk it appears “full” because no more files can be written (unless it is a R/W disk which can be rewritten). There is a special formatting (InCD) for optical disks that will allow you to copy and erase files from a disk, but all the space they occupy is gone from the disk, even if they are erased. However, the InCD formatting is not stable and isn’t used much anymore. The short answer is that you cannot free up space on an optical drive.
