Archives are where extractors meet their edge cases, so this category is built to exercise them. The ZIP set runs flat, nested, and deep-tree layouts, a unicode-filename archive, a zero-entry empty archive, and a hundred-tiny-files archive for stress-testing throughput. Tarballs ship uncompressed and as gzip, bzip2, and xz variants (.tar, .tgz, .tbz2, .txz), with single-file gzip, bzip2, and xz alongside so you can isolate the codec from the container. There's a resource JAR, a real ISO 9660 disk image, and a 7z archive plus a password-protected 7z with the password printed right on the page. Every archive is deterministic, documented down to its member list, and deliberately safe, no zip bombs, no executables, no hidden payloads.

Results start with a representative from each related test family. Use a card’s variant menu or the filters below to reach a specific format, profile, or failure case; every sample retains its own detail page and download.
Never. There are no zip bombs, executables, or hidden payloads. Every archive is deterministic and documented down to its member list, the 'stress' samples are just many tiny harmless files.
It's printed directly on that file's page, so you can test password-protected extraction end to end.
Each tar variant (.tar, .tgz, .tbz2, .txz) ships alongside single-file gzip, bzip2, and xz samples, so you can test the codec on its own or inside the tar container.
Yes, there's a unicode-filename ZIP, a zero-entry empty archive, and a hundred-tiny-files archive for throughput testing, plus a resource JAR and a real ISO 9660 disk image.
Start with one example from each use-case group, then continue through its other test families. Choose a use case, search, or filter to find a specific profile; a card’s variant menu contains its related samples.

Bundle
A dataset bundle ZIP (a CSV with its JSON Schema, a README, and a LICENSE), the way datasets are commonly distributed. For testing unpack-and-validate pipelines and dataset importers.
Bundles
Small ZIP SAMPLE (config-bundle.zip) for extractor and listing tests.
Compressed
A single text file compressed with bzip2: the container-free codec on its own, for testing decompression and codec detection.
Compression
A text file compressed with the LZ4 frame format (.lz4), the container-free codec on its own, for testing LZ4 decompression and codec detection.
Disk Image
A real ISO 9660 disk image with Joliet and Rock Ridge extensions for long filenames, holding a few documented text files. For testing ISO mounting, extraction, and conversion.
Empty
The smallest valid archive in this catalog: the 8-byte ar magic and nothing after it. ar has no trailer record, so end-of-file is the only end marker, and this is what an empty static library or an empty .deb control arc
Exports
SAMPLE activity JSONL for subject-access export pipelines.
Nested
Gzipped tarball SAMPLE companion for nested-archive conversion sets.
Nested Mixed
The nested-JAR layout an executable fat jar uses: a manifest with a Class-Path entry and a second JAR stored uncompressed under BOOT-INF/lib so it can be read in place without being extracted first. It contains resources
P8 Convert
JSON ground-truth manifest for the canonical compressed-TAR twins, publishing each safe path, byte count, and full SHA-256 digest. Stable P8 artifact p8-convert-archive-member-manifest.
Project
A realistic static-website project bundled as a ZIP: index.html with linked CSS, JS, and an SVG logo, plus a README. For testing project extraction, unpack-then-serve pipelines, and nested-folder handling.
Sevenzip
A 7-Zip archive using LZMA2 compression, containing a small documented file tree. For testing 7z extraction and conversion.
Tar Format
GNU tar's extension of the same header, identified by its own magic: long names get their own 'L' record, oversized numeric fields switch to base-256, and sparse files get an in-header map. All three archives in this gro
Tar Records
Three directory records with distinct modes, one of which - tree/empty/ - has no members underneath it and therefore exists only because the record does. A reader that synthesises directories from member paths alone sile
Tar Sparse
A 1 MiB file with a 1047552-byte hole in the middle, stored the old GNU way: typeflag 'S' and a four-slot sparse map written into the header block itself. Only 1024 bytes are actually in the stream, so a reader that igno
Tar Stream
A tar that ends immediately after its last member, with none of the two 512-byte zero blocks the format calls for. Plenty of writers do this and GNU tar reads it with a warning; readers that treat a missing end marker as
Tarball
A uncompressed USTAR of a small source tree, for testing tar extraction and the TAR container. Member timestamps are fixed for reproducibility.
Unix
A cpio archive in the newc (SVR4) format with four members: the Unix archive format used by initramfs and RPM. Hand-written to spec and documented down to its member list; for testing cpio extractors and converters.
The use-case group filter replaces the long list of category sections.
