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.Z is a compound archive format combining TAR archiving with Unix compress, one of the earliest general-purpose data compression tools available on Unix systems. The compress utility, originally written by Spencer Thomas, Joe Orost, and others around 1985, implements adaptive LZW (Lempel-Ziv-Welch) compression — a dictionary-based algorithm that builds a translation table during compression and decompression. The TAR layer bundles files with full Unix metadata into a single stream, and compress reduces the stream size typically by 40-60%. TAR.Z was the standard compressed archive format on Unix systems throughout the 1980s and early 1990s, before gzip emerged as a patent-free replacement. The LZW algorithm used by compress was subject to patent claims by Unisys (holders of the LZW patent through Sperry), which motivated the development of gzip as an unencumbered alternative. One advantage is universal legacy compatibility — TAR.Z files can be extracted on any Unix system, including very old installations where newer compression tools may not be available. The format's historical ubiquity means that decades of archived software, documentation, and system backups exist as TAR.Z files. While TAR.GZ and TAR.XZ have replaced TAR.Z for new archives, the uncompress/zcat tools remain standard on all Unix-like systems, ensuring continued accessibility of legacy archives.
