K3Sb

K3b (KDE Burn Baby Burn) is a free and open-source disc burning application for the KDE desktop environment. It provides a graphical user interface to create and burn data, audio, and video discs, as well as to manage ISO images. The program is commonly written as K3b; occasionally appears in variant capitalizations such as K3Sb, but the project remains the same.

K3b is tightly integrated with KDE and is built with C++ and the Qt toolkit. It is distributed as part of the KDE Applications suite under the GNU General Public License. The software relies on common burning backends and external tools to perform operations such as burning, ripping, and disc management. It supports burning to CD, DVD, and Blu-ray media on supported drives, as well as erasing rewritable discs, copying discs, and verifying data after burning. The user interface emphasizes wizard-driven workflows and drag-and-drop capabilities to streamline typical tasks.

The project is available across many Linux distributions and other Unix-like systems, with prebuilt packages for major distros and source code available for compilation on platforms with KDE and Qt support. K3b has established itself as a stable, long-standing option for disc authoring within KDE-focused environments and remains widely used for a range of burning tasks in those ecosystems.
