BZ2 uses bzip2 compression (better ratios than gzip for text/logs) often with tar as .tar.bz2. Common in Linux for source tarballs and large text compression. In 2026, still used in some archives for maximum size reduction on compressible data. Slower than gzip but worth it for big logs or datasets. 7-Zip handles BZ2 natively.
As part of the archive category, this format is highly optimized for its specific use case. Whether you are using it for professional or personal tasks, understanding how to handle .bz2 files is essential for efficient digital workflows.
Extract with 7-Zip or tar -xjf file.tar.bz2.
