writing to cd-r and cd-rw

I use both type of cd to back up files, using the 'Send to' instruction.
Normally I have no problem with this, but recently I have attempted to copy files to a disk and get a message saying that it is full, although I know that there is adequate space.
When I check the 'CD details', that also indicates there is not space available!
With cd-rw I know I can delete all items, but I am reluctant to destroy a cd-r when I know there is often about two-thirds of the disk unused.

Are you sure you are not "finalizing" the disks inadvertently?

It would certainly be inadvertently, as I don't know how to do that - and am not too sure what it means!!!

Pop a cd-r into your drive then open 'My Computer' if it says how much data is on it but also no space free then it has been finalized.

Which Burning program are you using? You may have set the 'settings' to finalize disks.

What it means is that you have made it unable to accept more data.

There may be a setting for "Multisession" which means you can write to the same disk several times.

Ashampoo do a Free Burning program which will let you choose whether to go Multisession or to finalize, simple to use.

Finalize is like breaking the tab on an old audio cassette or video tape, the difference is you can't use a bit of sticky tape to cover the hole and re-record, it a one way process.

Thank you for your contributions.
I use a simple "Save as ........." when copying files to the CD's.
I do not use any Burning program.
What puzzles me is that I regularly copy files to disks without any problems and them, without any change to the method I use, the disk shows as full or, it appears, becomes finalized.
The obvious solution would seem to be using only CD-RW disks, then when this happens, at least I can delete the files and start again.
Thanks, again, anyway.
