: The bzip2 tool is a high-quality data compressor that processes data in blocks ranging from 100 kB to 900 kB. Users sometimes refer to the maximum compression setting (often invoked as -9 ) and the file extension .bz2 in combination, which might lead to variations like "B90" for the 900 kB block size.

: Supports over 30 formats, including ZIP, 7Z, and BZ2. It features multi-core support for faster compression.

If you are looking for software to handle ZIP or BZIP2 files, these are highly-rated options:

: An older but historically significant version that introduced 64-bit extensions to remove file size limits.

: A cross-platform tool that handles password-protected and split archives across Windows, Mac, Android, and Linux.
