About formats
7Z is the native archive format of 7-Zip, an open-source file archiver created by Igor Pavlov in 1999. The format uses an open, modular architecture that supports multiple compression algorithms — LZMA and LZMA2 (the defaults), PPMd for text-heavy data, BWT, and Deflate — selectable per file within the same archive. LZMA typically achieves 30-70% better compression ratios than Deflate-based ZIP files on comparable data, making 7Z one of the most space-efficient general-purpose archive formats available. The container structure stores files with full directory hierarchy, timestamps, and attributes, while supporting solid compression (treating multiple files as a continuous data stream) for additional ratio gains on archives with many similar files. Encryption uses AES-256 with key derivation based on iterative SHA-256 hashing, and both file contents and filenames can be encrypted. One advantage is superior compression density — 7Z consistently produces smaller archives than ZIP or RAR on most data types, valuable when minimizing storage or bandwidth matters. The open architecture is another strength: the format specification and 7-Zip source code are publicly available under the GNU LGPL, enabling any developer to implement 7Z support without licensing constraints. Cross-platform tools supporting 7Z exist for Windows, macOS, Linux, and mobile platforms, and the format has gained widespread recognition as the preferred choice when maximum compression is the priority.
TAR.LZ is a compound archive format combining TAR archiving with lzip compression, a format created by Antonio Diaz Diaz and first released in 2009. The TAR layer bundles files with full Unix metadata into a single stream, and lzip applies LZMA compression with a robust container that includes per-member CRC-32 integrity checking and clean member boundaries. Lzip was designed with long-term archival in mind — it produces a simple, well-documented format with strong error recovery properties: if part of a TAR.LZ file is corrupted, undamaged members can still be extracted, unlike monolithic compressed streams where corruption propagates. The compression ratios are essentially identical to LZMA/XZ since lzip uses the same LZMA algorithm. One advantage is archival resilience — the member-based structure means a multi-part archive can survive partial corruption without losing all data, critical for long-term storage. The clean, minimal format design is another strength: lzip has a simple specification that independent implementations can follow precisely, reducing the risk of compatibility issues over decades of archival. TAR.LZ is used by the GNU Project for distributing source releases and is supported by GNU tar with the --lzip flag, as well as by plzip for parallel compression on multi-core systems.
