This is the first time I've been in a user group, so forgive me if I don't
do
everything right.
I'm trying to copy files to a CD, and it's also the first time I've done
that. I was able to copy a folder from my hard drive to the CD, and I can
open files within that folder on the CD. However, I experimented by
making a
change (they're all Word files, text, and I added a sentence to the
beginning
of one) to a file, then told Word to save it. I got an error message that
it
could not be saved, that the file is "read only." It shouldn't be. The
file
can be opened on the hard drive and edited with no problem, and the CD is
a
"CD-RW" disk, "Rewritable," and "Reinscriptable," and it was a blank disk.
The total size of the folder is minuscule compared to the storage capacity
of
the disk, so it didn't fill it.
If anyone can tell me what I'm doing wrong, I'd appreciate it, and I hope
this is the right place to put a question such as this.
You have misunderstood the way CD filing works. When files and folders are
copied to CD-RW (or CD-R) then they are copied in a read only mode because
the file and folder really cannot be changed. Material may be added, and
indeed an existing file or folder may be overwritten (it isn't really but
the system makes it look that way). The 'rewritable' description of the
CD-RW refers to its ability to be *completely* erased and have fresh folders
and files written.
What you want to do can be achieved with the use of a special CD writing
utility that uses 'packet incremental format'. Nearly all of the commercial
CD burning packages include such software, but Windows XP does not. You
should note that you should never store anything valuable on a CD in packet
incremental format unless you have another copy of it somewhere. For
technical reasons unlikely to become clear in this post, packet incremental
format has a low level of reliability because the drive can sometimes
overwrite the wrong area of a CD rendering it useless (and in some extreme
cases impossible to erase or reformat). If you really need to use packet
incremental format, then consider using a DVD+RW (not a DVD-RW) which does
not have these limitations.
