You can write data to a CD-R disk in multiple sessions until the session is closed or the disk becomes full. I've done it many, many times in the past. You can keep adding data to a multisession disk until its full. You can delete files too, you don't get the space back but they are removed from the index of what is on the disk. If you close the session, what is on the disk gets locked and you cannot edit it anymore.
