关于格式
ARC 是最早在个人电脑上广泛使用的压缩归档格式之一,由 System Enhancement Associates(SEA)公司的 Thom Henderson 于 1985 年为 MS-DOS 创建。该格式将多个文件合并到单个归档中,对每个文件单独压缩,支持多种压缩方法,包括不压缩(直接存储)、游程编码、霍夫曼编码和 LZW(Lempel-Ziv-Welch)变体。ARC 归档中的每个文件条目都有独立的头部信息,包含原始文件名、压缩和未压缩大小、时间戳、CRC 校验和以及压缩方法标识符。在 1980 年代中期,ARC 成为基于 DOS 的电子公告板系统(BBS)上的主流归档格式,在互联网时代到来之前,它是在线分发软件、文档和数据文件的主要手段。该格式引发了一场著名的法律纠纷 — Phil Katz 创建了一个兼容工具(PKARC),导致 SEA 对其提起诉讼,最终促使 Katz 开发了 ZIP 格式作为合法替代方案。ARC 的一大优势是其逐文件压缩方式,允许提取单个文件而无需解压整个归档。集成的 CRC 校验和提供了另一项优势,能在通过容易出错的调制解调器连接传输后可靠地验证数据完整性。虽然 ZIP 及更现代的格式在 1990 年代初取代了 ARC,但该格式作为数据压缩和文件分发演进史上的基础技术,具有重要的历史意义。
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.
