What is an LZ file?
The LZ file extension denotes a compressed archive generated by Lzip, a lossless data compressor based on the Lempel-Ziv-Markov chain Algorithm (LZMA). Developed by Antonio Diaz Diaz in 2008 to supersede the raw .lzma format, the LZ format prioritizes data integrity and long-term archival safety over pure speed. It utilizes a stream-based structure consisting of independent 'members,' allowing for the concatenation of files and robust error recovery via tools like lziprecover. Unlike the XZ format, the LZ specification simplifies the header structure while implementing a 4-factor data protection system, utilizing 32-bit Cyclic Redundancy Checks (CRC-32) to verify both header and data stream consistency.
How to open an LZ file
Most modern Windows and macOS configurations lack native kernel-level support for decoding LZ binaries and require third-party compression utilities. On Windows, users should utilize 7-Zip or PeaZip, which integrate the necessary LZMA decompression libraries. macOS users can extract these archives using The Unarchiver or via the command line by installing the lzip package through Homebrew. Linux distributions typically offer native support via the standard lzip command-line utility or through GUI archive managers like File Roller once the lzip package is installed from the repository.

What is a ZIP file?
The ZIP format is an archive file format capable of lossless data compression, originally created by Phil Katz of PKWARE. It utilizes a Central Directory structure to catalog files and supports various compression algorithms, most notably DEFLATE (RFC 1951). The format is standardized under ISO/IEC 21320-1:2015 as a document container file and serves as the base structure for modern file types like .docx and .jar.
How to open a ZIP file
The ZIP format enjoys universal native support across all major operating systems, including Windows (File Explorer), macOS (Archive Utility), and Linux. No third-party software is strictly required for basic extraction, though power users often employ tools like 7-Zip or WinRAR to access advanced features like AES-256 encryption or multi-volume spanning.
