About formats
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.
RAR (Roshal Archive) is a proprietary compressed archive format created by Russian software engineer Eugene Roshal in March 1993, distributed through the WinRAR) archiver that became one of the most widely installed Windows applications worldwide. The format uses a sophisticated compression algorithm that has evolved through several major versions (RAR 1.3, 2.0, 3.0, 5.0), with each revision improving compression ratios and adding features. RAR5, the current version, employs a dictionary-based algorithm with dictionary sizes up to 1 GB and supports optional BLAKE2sp hashing for integrity verification. The format provides solid compression (treating multiple files as a continuous stream), multi-volume archive splitting, recovery records for repairing damaged archives, AES-256 encryption for both content and filenames, and Unicode filename support. One advantage is reliable error recovery — RAR's recovery record feature can reconstruct damaged archive portions, a capability that made it popular for distributing large files across unreliable connections and Usenet posts. Strong compression performance is another key strength: RAR consistently ranks among the top formats for general-purpose compression ratios, particularly on heterogeneous file collections. While the compression algorithm is proprietary and creating RAR archives requires licensed software, the decompression code is freely available, and extraction is supported by virtually every archiving tool across all platforms. RAR remains one of the most common archive formats encountered online.
