What is a .7z file?
7z is the native archive format of 7-Zip, supporting high-ratio LZMA and LZMA2 compression, strong AES-256 encryption, and solid compression across multiple files. It bundles many files with a flexible header and typically outperforms ZIP on compression. It is popular for efficient archiving and distribution.
How to use this file
Use an example 7z to test 7-Zip-compatible extraction, LZMA decoding, solid-archive and multi-volume handling, and optional encrypted-archive support.
How to use this file for testing
“7z - LZMA2 Archive” is a deterministic Novus Examples fixture for Conversion testing. The same content exported across many formats and linked as a group, so you can convert one and diff against the expected twin.
Documented properties for this file: 7z (LZMA2). Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.
Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.
Archive fixtures are documented down to their member list (shown on this page) and are deliberately safe — no zip bombs, executables, or hidden payloads. Test extractors against nested, unicode, empty, and encrypted variants.
