copy to CD-RW not working

[Guest]

HELP! I have a presentation (ppt) and I want to copy it to a CD on which I
already have other presentations. There's plenty of room remaining on the
CD. The CD is a Verbatim DataLife Plus CD-RW 4X-12X speed. When I try to
copy to CD, however, it announces that the CD is read-only and I can't copy
to it. Can someone help? I'm running out of time! (and I don't have another
CD)

Hi Megan,

It sounds like you finalized the disk. If that is the case, then
there is nothing you can do to add a file to that disk.

You'll probably have to use a new/blank CD-RW or erase you current one,
which you would not like to do.
Should use a third party app like Nero or Roxio and format the CD-RW,
that way it will be just like a second harddrive. To which you can copy,
paste, add or delete etc. It is called packet writing. You can copy and
paste the PPT file and use the PowerPoint Viewer to view it.
