Testing contract
Expected to pass- Scenario
- Parse the MSCF cabinet, locate its one folder and one file, and extract the stored CFDATA block.
- Expected result
- control.txt extracts to the exact CRLF-terminated text 'P8 CAB extraction control' and no secondary volume is requested.
What is a .cab file?
CAB is Microsoft's Cabinet archive format for bundling compressed files and installation resources. An MSCF header points to folder and file tables; data blocks may use no compression, MSZIP, Quantum, or LZX, and a cabinet can participate in a multi-volume set.
How to use this file
Use an example .cab file to test MSCF signature and table parsing, member names and sizes, bounded block decompression, unsupported-codec reporting, path-traversal defenses, and comparison with a published member manifest.
How to use this file for testing
“Convert v2 CAB Stored Control” is a deterministic Testaroo 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: CAB · 107 bytes. 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.

- zipZIP - All Members DeflateA ZIP whose every member uses compression method 8 (deflate). 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.
- zipZIP - All Members StoredA 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.
