关于格式
7Z 是 7-Zip 的原生归档格式,由 Igor Pavlov 于 1999 年开发的开源文件压缩工具。该格式采用开放的模块化架构,支持多种压缩算法 — LZMA 和 LZMA2(默认算法)、适用于文本密集数据的 PPMd、BWT 以及 Deflate — 同一归档内的不同文件可分别选用不同算法。LZMA 的压缩率通常比基于 Deflate 的 ZIP 文件高出 30-70%,使 7Z 成为空间效率最高的通用归档格式之一。容器结构存储带有完整目录层级、时间戳和属性的文件,同时支持固实压缩(将多个文件视为连续数据流处理),在包含大量相似文件的归档中可进一步提升压缩率。加密方面采用 AES-256,密钥派生基于迭代 SHA-256 哈希,文件内容和文件名均可加密。7Z 的一大优势在于卓越的压缩密度 — 在大多数数据类型上,7Z 始终能生成比 ZIP 或 RAR 更小的归档,这在需要最小化存储或带宽时尤为重要。开放架构是另一项优势:格式规范和 7-Zip 源代码以 GNU LGPL 许可证公开发布,任何开发者都可以在无许可限制的情况下实现 7Z 支持。支持 7Z 的跨平台工具覆盖 Windows、macOS、Linux 及移动平台,该格式已被广泛认可为追求最大压缩率时的首选。
TAR.LZMA is a compound archive format combining TAR archiving with the LZMA (Lempel-Ziv-Markov chain Algorithm) compression method developed by Igor Pavlov for the 7-Zip project around 1998. The TAR layer concatenates files with Unix metadata into a single stream, and the LZMA algorithm compresses it using a sophisticated combination of LZ77 dictionary matching with large dictionaries (up to 4 GB), Markov chain-based probability modeling, and range coding. LZMA was the predecessor to the LZMA2 algorithm used in XZ and 7Z formats. Compression ratios significantly exceed gzip and are comparable to bzip2 while offering substantially faster decompression. One advantage is the high compression ratio with fast extraction — LZMA decompresses at speeds close to gzip while achieving compression densities near bzip2 or better, making it efficient for distribution archives that are compressed once and extracted many times. The format is supported by tar's --lzma flag and by 7-Zip across all platforms. While TAR.LZMA has been largely succeeded by TAR.XZ (which uses LZMA2 in a more robust container with integrity checks), existing TAR.LZMA archives remain encountered in software distributions and backup systems that adopted the format before XZ became widely available.
