Copying to a CD

[Teresa Peereboom]

I copied files to a CD and everything is fine when I try to view them etc.
Now I want to add more info to the CD but it just seems to overwrite
everything. Is it possible to add more data to a CD or will I lose all my
previous files. Thanks

Have a great day!

The answer to that question has several conditions. What happens on
the CD is dependent upon the Cd writing program, the type of CD and
the method of writing. If you use a CD-R, you can write to the disk
but you cannot erase what is already written to the disk. The
operation may be single session where the disk is closed to all
writing when the task is finished regardless of how much space was
used. The operation may be multi-session where you can write to the
disk in several separate operations. Each new session may include
some or all of the previous session. The new session is written on
a new part of the disk.

Some program allow you to write to a CD-R or CD-RW disk as if they
were floppy disk. With a CD-R disk, files may be deleted but the
space cannot be occupied again. With CD-RW disk, the disk can be
formatted and erased so that the space can be used again.

Although files on CD-RW can be erased, this is only possible if
files are written using the Universal Disk Format. If you write to
a CD-RW disk with the file format used for CD-R disk, you cannot
erase individual files. You have to erase the entire disk to add
new files or get rid of unwanted files.

Usually the packet-writing or UDF programs are separate from the
regular CD burning software. In the case of Nero, the burning
software is called ROM Burning, while the packet-writing software is
called InCD. The latter only works on CD-RW disks. The
packet-writing software from Roxio and Pinnacle will work on CD-R as
well as CD-RW disk.

This is a brief overview. If I left something out or said something
incorrectly, other may jump in to set the record straight.

Thanks for your response,
I am fairly new to this so I'm trying to understand what your saying. I
understand about CD-R and CD- RW. I think what your saying is that
regardless of what type of CD I'm using I cannot "Add" anything to the
CD... I must erase, write-over, and use another CD. Is that correct?. This
"packet-program" or UDF program you talk about will that allow me to do what
I want? Where can I learn about that program. Thanks very much

I am not sure what the other post told you but I have
Roxio Easy CD Creator which came with XP HE and using a CD-
RW I can add and delete files at will. Use the import
session setting. There is lots of help in the help and
support as well as well as the help button at the top of
the application. That's what they're there for. That way
we don't have to write a book in response to questions
like this one. Good luck.

I said that unless you use packet-writing software or run a
multi-session on a CD-R or CD-RW disk, you can only write once to
the disk regardless of how much space is left on the disk. You can
only erase files individually from CD-RW disk if you use
packet-writing software. The software included with Windows XP is
not packet-writing. Once you write the files from the staging you
close a session. You cannot delete individual files. You can copy
new files to the staging area and write another session until the
disk is full. CD-RW disk are treated the same way in Windows XP CD
writing as CD-R disks. You cannot erase or revise individual files.
You need other companies' software to do this.

Go to http://www.ahead.de to download a trial of their Nero ROM
Burning software and their InCD packet-writing software to see how
they work. NTI at http://www.ntius.com has similar software and
offer free trials also.

How can you offer advice if you do not even read the preceding
messages? You should include part of the message or at least the
reference to the message to which you are replying in your message
so that others will not have to hunt for the original message to see
what you are talking about. For those who use the web-based
interface to the read newsgroups, you are making it difficult for
them to find your responses because you create new messages rather
than replying to the message you have open. You should have empathy
for those, including yourself, who use the web-based interface and
make your messages more user-friendly.
