Reference control- Scenario
- Identify .tbz2 as bzip2-compressed TAR, decompress it, and compare the two member hashes.
- Expected result
- project/brief.md and project/config.json extract byte-for-byte with the canonical member hashes; suffix spelling does not alter semantics.
What is a .tbz2 file?
TBZ2 is a shorthand extension for a TAR archive compressed with bzip2, equivalent to .tar.bz2. The tar step bundles files and metadata, then bzip2 compresses the combined stream for a higher ratio. It is used for distributing larger source and data archives.
How to use this file
Use an example TBZ2 to test the decompress-then-untar pipeline with bzip2, and tools that recognize the abbreviated .tbz2 extension.
How to use this file for testing
“Convert v2 TBZ2 Alias” 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: TBZ2 · 207 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.

- tarTAR Containing Three ZIP ArchivesA tar carrying three ZIPs: two byte-identical and a third holding the same content stored rather than deflated. A deduplicating packer should notice the first two are the same object; a content-addressed one should notice all three extract to the same files.
- tbz2TBZ2 - Empty ArchiveThe empty tar under bzip2. Its payload is 1024 identical bytes, which is the run-length case bzip2's block sorter treats specially, so this doubles as the smallest sane bzip2 stream to test a decoder against.

- 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.
