Creating audio CD and deleting same

I tried to create an audio CD with DO and never was able to do so and now every time I reboot the PC DO pops up a balloon that says I have files to burn. How can I get rid of this notification?
What are the steps to creating an audio CD using DO?
Tanks!

Opus does not have any CD burning capabilities of its own; it just lets you use the ones that are built into Windows, which work the same in Opus as they do in Explorer.

A search on "files to burn" finds this guide on removing the temporary files which are waiting to be written to disk:

(The details may be slightly different in other versions of Windows, but there should be similar guides for each version if you add the Windows version to the web search. Similarly for information on how to burn files to a CD, e.g. How to Burn Files to a CD or DVD using WIndows 7 comes up in the same search as above and the details apply to both Explorer and Opus.)

Thanks LEO!!!
