After a long day of research i am ableto answer my own question and help others who may have the same question:
No, it won't fit. The file is too big.
Beyond that, audio is written to CD as CD-Audio, and is counted in minutes. It's PCM (pulse-code modulation) digital audio data -- there are no files on audio CDs. A 700MB CD-R will hold 80 minutes of audio, and that's it.
The only other choice is to use the 99-minute CD-R. However, these discs are no longer made (as far as I know), and they were not always reliable. I'd certainly suggest against them for any archival use.
This person may simply need to split his/her content onto two discs.
