About formats
ALZ is a proprietary archive format created by ESTsoft, a South Korean software company, as the native format of their ALZip archiver first released in 1999. The format was designed to address a specific need in the Korean market: splitting large archives into multiple volumes for distribution when email attachment size limits and slow internet connections made transferring large files impractical. ALZ archives support file compression, multi-volume splitting with configurable segment sizes, and basic file organization with directory structures. The format became widely adopted in South Korea, where ALZip established itself as one of the most popular archiving utilities due to its free availability for personal use and localized Korean interface. At its peak, ALZip was installed on a majority of Korean personal computers, making ALZ a common interchange format for file sharing within the country. One advantage is reliable multi-volume handling — ALZ was specifically engineered for splitting and reassembling archives across volume boundaries, a feature that was central to its design rather than an afterthought. The format's tight integration with ALZip provides a streamlined user experience for compression and extraction tasks. While ALZ saw limited adoption outside South Korea due to the availability of universal formats like ZIP and RAR, it remains encountered in files originating from Korean sources and can be extracted using ALZip, 7-Zip, and other compatible utilities.
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.
