ZIP - All Members Stored

A ZIP whose every member uses compression method 0 (stored). Its twin holds byte-identical content under the other method, so an extractor, a size estimator, or a repacking pipeline can be compared on the same payload with only the storage method changed.

Testing contract

Expected to pass
Scenario
Extract both members of the stored/deflate twin pair and compare the payloads and the reported per-member compression method.
Expected result
Every extracted member is byte-identical across the pair, and this archive reports method 0 (stored) for all 3 members.

What is a .zip file?

ZIP is a widely supported archive format that bundles multiple files and directories into one container, typically with per-file DEFLATE compression and a central directory index. It supports random access to individual entries without decompressing the whole archive. It underlies many document formats such as DOCX and EPUB.

How to use this file

Use an example ZIP to test archive extraction, central-directory parsing, per-entry decompression, and protection against path-traversal (zip-slip) during unpacking.

How to use this file for testing

“ZIP - All Members Stored” is a deterministic Novus Examples fixture for Conversion testing, Compression 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: seed 20260807. 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.

unzip -l method-stored.zip     # list members
