K3b was created to be a feature-rich and easy to handle CD and DVD burning application. It consists of basically three parts:

• The projects: Projects are created from the file menu and then filled with data to burn
• The Tools: The tools menu offers different tools like CD copy or DVD formatting
• Context sensitive media actions: When clicking on the icon representing a CD/DVD drive K3b will present its contents and allow some further action.
