Yes and No!
CD and DVD works as you say if one finalize.
I have two DVD recorders for video TV.
They have built in TV receivers so I can see
all the channels. As long as I don finalize
I can shut down for that day and continues
some other day and add more tv shows.
Only after a Finalize is it not writable.
And I can delete shows and the only bad thing
that happens are that the show become invisible
to the software and to me. It is still there in
the groves but it is marked as deleted.
What I tried to ask what in what order the BIOS
read the added material.
If your curious in Puppy Linux multi-session CD and DVD

So, when you boot Puppy, if tracks are read in reverse order and the latest version of each file copied to your home directory in the ramdisk, what about deleted files? Say you delete a file during one session, that has previously been saved to DVD at the last session, won't it come back again next time you boot? No, Puppy has a mechanism that keeps track of deleted files and this won't happen. However, that does raise an interesting point ... the deleted file is still on the DVD, meaning that every single file that ever existed will be recorded on the DVD, meaning that you have a perfect audit trail of past activity.

That is how Puppy do it but I ask how the Bios do it.
I guess theres a wiki or a Ms text somewhere on internet but I have not
enough fantasy to know which search word to use and even if I had the
writer of that text never thought one would need such knowledge either.
Barry who made Puppy wrote that it is a world first almost. Just one
group doing it before him and their thing seems not to be widely known
while Puppy is among the 20 most popular distros.
so if Bios do the same as Puppy does then the bios would first find the
newest added iso and use that one. that would be smart. The updated iso
would be the one given priority. But I fear that is not the case.
But you can add material that is what I do every day but I have no clue
on in what order it get read by the Bios.
To use rewritables. Barry write about them too.

I do not recommend a CD-RW simply because it isn't necessary. A CD-R is "write-once", but in multisession mode, tracks can be written one after the other, up to 99 tracks or the CD-R becomes full.

I have four DVD+RW so I can use them to test isos with and when I find an iso I like I can use the 7 CD I have to save them forever.
