I used a CD-R disc to write some data to it, then later in the day I wanted to add more data to the same disc. I tried to write more data to the disc and got the message that the disc was full, the disc size is 700 MB and I only used 100 MB the first time. So I should be able to add at least 600 MB of data to the disc before it is full. I know with a windows base computer you have programs like Roxio or Nero so you can add data to a CD-R. Is ther e anything similar for a Mac computer.
Thanks
