I am trying to burn a file to a CD-R. I don't think that I finalised the CD in another programme.

However, I note, when trying to burn a file, that I cannot select the folder on the disk, and the Burn button is grey.

Further, When burning to a CD-R, how can I be sure that the disk is not finalised so that I can add files at a later date to a CD-R?

Thanks

Ps. I read the UBUNTU page that discusses burning using k3b. It mentions 'Wizard Mode'. I can't find such a mode in k3b. Hence, I simply moved the file to the pane that contains the programme options.
