I've copies 2 picture files to a CD-R.
I want to delete one of them.
I know I can't delete files once placed on a CD-R but I understand I could
replace one of the picture files with another file.
How?
Thanks,
ps I'm doing this via XP

Once you write to a cd-r you can't delete or overwrite the file. So the
files that are on there are there for eternity or when the cd crumbles to
dust.
 
Once you've written to a CD-R the information cannot be changed. It's like
footprints in cement. What you can do is to add the new picture files if
there's room. The old file can be 'deleted' but it's not true deletion. You
don't get the space back.

Only if the original CD-R was burned as multi-session.
 
You can't reuse the space on your CD-R that was occupied by a file. But you
can replace the file with another of the same name. It will change the
"table of contents" to not show the old file and point to the new file.
Both the old version and the new version will be on the CD-R but the CD
contents will only show the new file.

For the price of a cdr why bother? :O)

Wrong.

You can write another file, to the same folder, that has the same
name, onto the CDR. The TOC pointer will be moved from the old file
to the new file. Although the old file will still occupy space on the
CDR, it isn't visible or usable, and as such, seems as though it was
deleted.
 
It is possible to write a CD that is not closed. More data can be added
later and even data removed (it isn't actually removed the directory is
rewritten and without a mention of the files location it can't be found
easily. So the question becomes did he close the CD after he wrote it or
leave it open?
 
I don't think so. If it was an open session you can add and delete
information during a later session. The space has still been taken by the
initial write but the new directory doesn't allow you to easily get there.

When you use the inbuilt burning it burns a set of files at once, as a
'session'. If you put the CD back, and look in My Computer, there is a
section of 'Files waiting to be written' - items there will form a
second session, and subsequently My Computer/Explorer will see the files
in both sessions as on the disk. If one of the files in the second
session has *exactly* the same name as one in the first, that newer one
will be the one that gets seen
