How do I transfer emails to a CD and be able to rewrite/edit the material (what type of CD)?

I'd like to empty a folder of emails yet be able to view them and rearrange if needed, and add more to the CD as more emails come in. If this is possible, how is it done? Is there a specific CD type needed for this task?|||You can copy and paste them to a folder, name, date, etc. and then burn the CD. Don't finalize and leave the CD session open to add more files at a later date.
