can't open file from disc

[Joey]

I saved some file in a CD-RW. It may be too full, now I can't open some file,
I can't even copy or save file anymore. But, there is some important files
inside, I can't delete the files. What can I do?

Use Windows Explorer to copy the needed files from the CD to the Hard
drive. Post further questions relating to file handling and the
operating system to a group intended for addressing those kinds of
problems. The group name will have the Operating system version in it.
