why 4 partitions?

[hong jun <hj_182002@yahoo.ca>]

thank you very much.
again, i have this question, you say:
"Apt-cdrom does not work.  What I reccommend is that the contents of the
cdrom's be copied into four separate partitions and the
/etc/apt/sources.list be edited to point to these partitions, e.g.
deb file:/discs/A/debian sid main contrib local
deb file:/discs/B/debian sid main contrib local
etc."
so i wonder :can i put these cdroms content in one partition?
and the /etc/apt/sources.list is edited like the two lines upon which
header with"deb file:/......"

please help me.
