7-Zip Archive - open-source format by Igor Pavlov (1999) providing the best compression ratio available (20-40% better than ZIP, 10-15% better than RAR). Uses LZMA and LZMA2 algorithms with strong AES-256 encryption. Supports huge file sizes (16 exabytes), multiple compression methods, solid compression, and self-extracting archives. Free from licensing restrictions and patent concerns. Perfect for maximizing storage efficiency, software distribution, and backup archives where size matters. Requires 7-Zip or compatible software but offers exceptional space savings.

Unix Formats

TAR

TAR Archive - Tape Archive format from Unix (1979) bundling multiple files and directories into single file without compression. Preserves file permissions, ownership, timestamps, and symbolic links critical for Unix systems. Often combined with compression (TAR.GZ, TAR.BZ2, TAR.XZ) for efficient distribution. Standard format for Linux software packages, system backups, and cross-platform file transfer. Essential for maintaining Unix file attributes. Works with streaming operations enabling network transfers and piping. Foundation of Unix/Linux backup and distribution systems.

GZ/TGZ

GZIP/TGZ - GNU zip compression format (1992) using DEFLATE algorithm, standard compression for Linux and Unix systems. TGZ is TAR archive compressed with GZIP. Fast compression and decompression with moderate ratios (50-70% reduction for text). Single-file compression commonly paired with TAR for multi-file archives. Universal on Unix/Linux systems with built-in 'gzip' command. Perfect for log files, text data, Linux software distribution, and web server compression. Streaming-friendly enabling on-the-fly compression. Industry standard for Unix file compression since the 1990s.

BZ2/TBZ2

BZIP2/TBZ2 - block-sorting compression format by Julian Seward (1996) offering better compression than GZIP (10-15% smaller) at the cost of slower processing. TBZ2 is TAR archive compressed with BZIP2. Uses Burrows-Wheeler transform achieving excellent ratios on text and source code. Popular for software distribution where size matters more than speed. Common in Linux package repositories and source code archives. Ideal for archival storage, software releases, and situations prioritizing compression over speed. Standard tool on most Unix/Linux systems.

XZ/TXZ

XZ/TXZ - modern compression format (2009) using LZMA2 algorithm providing excellent compression ratios approaching 7Z quality. TXZ is TAR archive compressed with XZ. Superior to GZIP and BZIP2 with ratios similar to 7Z but as single-file stream. Becoming the new standard for Linux distributions and software packages. Supports multi-threading for faster processing. Perfect for large archives, software distribution, and modern Linux systems. Smaller download sizes for software packages while maintaining fast decompression. Default compression for many current Linux distributions.

TGZ

TGZ - TAR archive compressed with GZIP compression. Combines TAR's file bundling with GZIP's compression in single extension (.tgz instead of .tar.gz). Standard format for Linux software distribution and source code packages. Maintains Unix file permissions and attributes while reducing size 50-70%. Fast compression and decompression speeds. Universal compatibility on Unix/Linux systems. Perfect for software releases, backup archives, and cross-platform file transfer. Abbreviated form of TAR.GZ with identical functionality and structure.

TBZ2

TBZ2 - TAR archive compressed with BZIP2 compression. Better compression than TGZ (10-15% smaller) but slower processing. Uses Burrows-Wheeler block sorting for excellent text compression. Common in Linux distributions and software packages where size is critical. Maintains Unix file permissions and attributes. Perfect for source code distribution, archival storage, and bandwidth-limited transfers. Abbreviated form of TAR.BZ2 with identical functionality. Standard format for Gentoo Linux packages and large software archives.

TXZ

TXZ - TAR archive compressed with XZ (LZMA2) compression. Modern format offering best compression ratios for TAR archives (better than TGZ and TBZ2). Fast decompression despite high compression. Supports multi-threading for improved performance. Becoming standard for Linux distributions (Arch, Slackware use TXZ). Maintains Unix permissions and symbolic links. Perfect for large software packages, system backups, and efficient storage. Abbreviated form of TAR.XZ representing the future of Unix archive compression.

LZMA

LZMA/TAR.LZMA - Lempel-Ziv-Markov chain Algorithm compression format (2001) offering excellent compression ratios. TAR.LZMA combines TAR archiving with LZMA compression. Predecessor to XZ format using similar algorithm but older container format. Better compression than GZIP and BZIP2 but superseded by XZ/LZMA2. Still encountered in older Linux distributions and legacy archives. Slower compression than GZIP but better ratios (similar to XZ). Modern systems prefer TAR.XZ over TAR.LZMA. Legacy format for accessing older compressed archives from 2000s era.

LZO

LZO/TAR.LZO - Lempel-Ziv-Oberhumer compression format prioritizing speed over compression ratio. TAR.LZO is TAR archive compressed with LZO. Extremely fast compression and decompression (faster than GZIP) with moderate ratios (30-50% reduction). Popular in real-time applications, live systems, and scenarios requiring instant decompression. Used by some Linux kernels and embedded systems. Common in backup solutions prioritizing speed. Perfect for temporary compression, live CD/USB systems, and high-speed data transfer. Trade-off: larger files than GZIP/BZIP2/XZ but much faster processing.

Z

Z/TAR.Z - Unix compress format from 1985 using LZW (Lempel-Ziv-Welch) algorithm. TAR.Z is TAR archive compressed with compress command. Historical Unix compression format predating GZIP. Patent issues (until 2003) led to GZIP replacing it. Legacy format with poor compression by modern standards. Rarely used today except in very old Unix systems and historical archives. If you encounter .Z or .tar.Z files, convert to modern formats (TAR.GZ, TAR.XZ) for better compression and wider support. Important for accessing ancient Unix archives from 1980s-1990s.

常见问题

什么是 ISO 文件,为什么它被广泛用于分发操作系统和软件?

ISO 文件是从光盘(如 CD、DVD 或蓝光)创建的逐扇区磁盘映像。它精确捕获整个文件系统,包括引导扇区、目录结构、元数据和所有文件内容,完全与原始光盘一致。

ISO 映像成为分发操作系统、安装介质和大型软件包的通用格式,因为它们保留了可引导性,在系统间保持一致的结构,并且可以轻松挂载或刻录。

今天,尽管光盘在物理上不再常见,ISO 文件在虚拟化、操作系统部署、恢复工具、仿真和数字归档中仍然至关重要。

为什么 ISO 文件与其他归档格式相比如此庞大?

ISO 文件是原始光盘的精确克隆,默认情况下不压缩其内容。每个扇区(包括未使用区域)都被保留以确保准确性。

ISO 必须保留整个文件系统才能保持可引导性,这阻止了激进的压缩或内容重组。

与 ZIP、7Z 或 TAR 不同,ISO 优先考虑结构的保真度,而不是文件大小的减少,使输出大小与原始介质相似。

为什么我的计算机无法挂载或打开某些 ISO 文件?

某些 ISO 映像使用专用文件系统,如 UDF、HFS+ 或混合格式,这些格式仅在特定操作系统中得到完全支持。

损坏的下载——尤其是中断的操作系统映像——导致挂载工具由于校验和不匹配或扇区不完整而失败。

某些 ISO 文件包含高级引导加载程序或多个分区布局,需要专用挂载工具才能正确解释。

为什么我不能直接修改ISO内部的文件?

ISO是只读的磁盘映像,模拟光盘的结构,而光盘本质上是不可重写的。

要修改ISO,您必须提取其内容,重建文件系统,并使用适当的工具重新生成映像。

可引导的ISO需要特殊的重建步骤,因为在不重新生成引导记录的情况下修改内部结构会破坏引导兼容性。

为什么ISO在写入USB驱动器后有时无法引导?

并非所有ISO文件都是USB可引导的——它们可能仅设计用于CD/DVD引导,除非使用Rufus或dd等工具进行适配。

Incorrect partition scheme selection (MBR vs GPT) or the wrong boot mode (Legacy BIOS vs UEFI) prevents proper startup.

一些ISO包含混合引导设置,需要特定的写入方法,而不是通用的复制。

ISO文件使用起来安全吗?

ISO文件本身不包含加密或身份验证,因此其完整性取决于原始来源的可信度。

许多操作系统提供校验和或数字签名(SHA-256,GPG)来验证真实性并防止篡改。

在使用之前可以检查ISO内容,从而降低与隐藏可执行文件或恶意脚本相关的风险。

为什么某些ISO文件有多个分区或引导模式?

现代ISO通常包括混合引导支持,使其能够在Legacy BIOS、UEFI或两者上启动。

某些ISO包含用于恢复工具、EFI引导加载程序或制造商实用程序的额外分区。

混合ISO通过在硬件和虚拟化环境中通用工作来简化分发。

为什么不同系统在打开ISO时显示不同的内容?

某些ISO包含多个重叠的文件系统——例如ISO9660、Joliet、Rock Ridge或UDF——每个文件系统针对特定操作系统进行了优化。

Windows, macOS, and Linux each prioritize different layers, causing variations in visible file naming, long filename support, or directory hierarchy.

这种设计确保与数十年的硬件和软件标准向后兼容。

ISO文件容易损坏吗?

大型ISO下载容易因网络中断或部分写入而损坏,尤其是对于多吉字节的操作系统映像。

ISO引导扇区和文件系统元数据对小数据错误敏感,即使大部分内容完好无损也会导致失败。

校验和验证是确保下载或传输后完整性的最安全方法。

为什么虚拟化平台如此依赖ISO文件?

ISO提供了一个通用、标准化的操作系统安装介质容器,兼容VMware、VirtualBox、Hyper-V、QEMU等。

可引导的ISO简化了自动部署、快照和环境重置。

它们允许一致、可重复的系统配置,而不依赖于物理介质。

ISO适合长期数据归档吗?

ISO完美保留文件系统结构,使其成为归档软件分发和原始光盘映像的理想选择。

然而,与较新的归档格式相比,ISO9660在现代文件大小、文件名和元数据方面存在限制。

对于长期存储,将ISO与外部校验和或包装结合使用可以提高完整性保证。

ISO文件可以存储压缩或去重数据吗?

原生ISO格式不支持压缩;它们保持较大以保留精确的光盘布局。

然而,如果不需要引导功能,ISO可以包装在ZIP、7Z或TAR.XZ等压缩容器中。

一些专业工具生成优化或修剪过的ISO,但这些是非标准的,可能会破坏兼容性。

为什么某些ISO包含隐藏或无法访问的文件?

引导扇区、El Torito结构和EFI分区存在于可见目录树之外。

专业文件系统存储额外的元数据或指令,这些内容被挂载工具故意隐藏以确保用户安全。

系统安装程序通常包括隐藏在普通文件浏览器之外的内部工具或自动运行脚本。

ISO在今天仍然相关吗?

是的——ISO仍然是操作系统安装、恢复环境、虚拟机和仿真的通用标准。

它们的可靠性和一致的结构使其在现代云工作流程中也能持久耐用。

尽管有较新的格式,ISO在兼容性和简单性方面仍然无与伦比。

您应该使用ISO文件进行常规文件压缩吗?

不。ISO旨在保留精确的文件系统,而不是压缩或减少文件大小。

ZIP、7Z或TAR.GZ等格式提供更好的压缩、灵活性和元数据处理。

将ISO专门用于可引导介质、光盘映像、虚拟化或归档保存——而不是一般压缩。
