what are bz2 files

PeaZip is a free cross-platform file archiver utility that provides an unified portable GUI for many Open Source technologies like 7-Zip, FreeArc, PAQ, UPX... free alternative to WinRar, WinZip and similar proprietary software.
- Create 7Z, ARC, BZ2, GZ, *PAQ, PEA, QUAD/BALZ, TAR, UPX, WIM, XZ, ZIP files
- Open and extract ACE, ARJ, CAB, DMG, ISO, LHA, RAR, UDF, ZIPX files and more,
over 180 archive types supported
Features of PeaZip includes:
archives opener and extractor, manage bz2 format, batch creation and extraction of multiple archives at once, convert files, create self-extracting archives, split and join files, strong encryption with two factor authentication, encrypted password manager, secure deletion, find duplicate files, calculate hash and checksum, export job definition as script.

What is BZ2 format, BZip2 compressed files



BZ2 extension



BZ2 extension designates a pure data compression format not providing file archival feature, its BZip2 compression algorithm is based on Burrows–Wheeler transform.

Compression speed is somewhat slower than in zip format and gzip format, which employs classic Deflate algorithm (even if correctly implemented Bzip2 algorithm can be easily made parallel, and benefit of recent multi-core CPU), but faster than more powerful compression schemes as in RAR format, 7Z format, and new ZIPX format. Compression ratio, also, is usually intermediate between older Deflate-based ZIP/GZ files and modern RAR, 7Z, ZIPX formats.

Compressed files are usually identified by .bz2 extension, and can contain a single input file.
Due this by-design limitation, on Unix/Linux systems BZip2 compression (as well as Gzip, XZ,...) is usually cascaded to TAR archiving -  multiple files data and metadata (file attributes, date/time etc) are consolidated into a single uncompressed .tar container - producing TBZ2 file, which can be identified with TBZ, TB2, or TAR.BZ2 extension. Hint: learn more about files with double extension.

When is BZ2 compression recommended

BZip2 compression is usually applied to TAR archive format, which is usually employed to provide archiving of data and metadata on Unix and Unix-like systems, and it can also be used as alternative compression algorithm in ZIP and 7Z files - resulting archives can be read from most file archivers (including PeaZip).
It can be recommended when it is desired a better compression than classic Deflate-based ZIP compression, and in all cases it is preferable an algorithm faster and less heavy on memory and CPU than LZMA-based 7Z or PPMd-based RAR compression.

PeaZip features creation and extraction of BZ2 files, can read (open, test and extract) and write (compress to) BZ2 file type. Also, PeaZip can be set to use BZip2 compression as alternative algorithm for ZIP and 7Z formats, in Advanced options tab.

SPEED bz2 format specs
BZ2 format features good speed. Designed with parallelism in mind bzip2 compression can be, theoretically, implemented as separate threads for each input part.







COMPRESSION RATIO bzip2 algorithm specs

BZ2 format features good compression ratio, improved over Deflate but lacking behind modern compression algorithms employed in RAR and 7Z formats.

ADVANCED OPTIONS bzip2 features

BZ2 format is meant only for providing single-file compression, lacks archiving and encryption features by design.
