What is a tar.xz file?

A tar.xz file is a Tape Archive (tar) compressed using XZ Utils, which implements the LZMA2 (Lempel-Ziv-Markov chain algorithm 2) compression algorithm. Maintained by the Tukaani Project, this format replaces the older bzip2 standard in many Linux distributions (such as Fedora and Arch Linux) due to its superior compression ratios. It utilizes a dictionary size of up to 4 GB and typically employs CRC64 for data integrity verification, making it ideal for distributing large software source code packages and kernel archives.

How to open a tar.xz file

Most modern Linux distributions support this format natively via GNU tar version 1.22 or later using the command tar -xf file.tar.xz. Windows users can rely on 7-Zip (version 9.04 beta and above) or WinRAR 5.0+, which fully support the LZMA2 stream. macOS users can extract these files using the Archive Utility in newer OS versions or via the command line tool xz.

What is a TAR file?

The TAR (Tape Archive) format is a file format standardized by POSIX.1-1988 and later POSIX.1-2001 (pax), originally developed for writing data to sequential I/O devices like magnetic tape drives. Unlike modern archive formats, TAR is purely a container format that concatenates multiple files into a single archive without native compression, preserving file system attributes such as user/group permissions, dates, and directory structures. It is frequently paired with compression utilities like Gzip or Bzip2 in Unix-like environments.

How to open a TAR file

Most Unix-based systems (Linux, macOS, BSD) include native support via the GNU Tar command-line utility. Windows does not natively support TAR extraction in versions prior to Windows 10 (Build 17063), requiring third-party tools. For cross-platform compatibility, 7-Zip and WinRAR are standard utilities for inspecting and extracting TAR containers.
