Nautilus Section 7.11 Writing CD's (erase CD-RW)

[THUFIR HAWAT]

"5. Use the Write Files to a CD recorder dialog to specify how you
want to write the CD, as follows:

Dialog Element  Description
..
Erase CD        Select this option to erase the current contents of the CD."

Two questions:
a.)  where are the help files on the internet?
b.)  where's the  "erase CD" option?

there're three categories:  "Information", "Write Options" and "After
Writing" in the "Write to Disc" dialog.

Thanks,

Thufir
