7z - LZMA2 Archive
A 7-Zip archive using LZMA2 compression, containing a small documented file tree. For testing 7z extraction and conversion.
Archives
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.
Sevenzip
7z - Password Protected
A password-protected 7z archive (AES-256, encrypted header). The password is “novus-example” — printed here on purpose so you can test encrypted-archive extraction. Contains only harmless sample text.
Compressed
BZ2 - Bzip2 Single File
A single text file compressed with bzip2 — the container-free codec on its own, for testing decompression and codec detection.
GZ - Gzip Single File
A single text file compressed with gzip — the container-free codec on its own, for testing decompression and codec detection.
XZ - XZ Single File
A single text file compressed with xz/LZMA — the container-free codec on its own, for testing decompression and codec detection.
Disk Image
ISO - 9660 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.
Zip
JAR - Resource Archive
A Java Archive (JAR) — a ZIP with a META-INF/MANIFEST.MF and resource files only (no .class bytecode). For testing JAR/ZIP readers and manifest parsing.
ZIP - Deep Directory Tree
A ZIP archive — a file nested six directory levels deep. Deterministic (fixed member timestamps) and safe to extract anywhere.
ZIP - Empty Archive
A valid ZIP with zero entries — the empty-archive edge case for testing how unarchivers handle a container with nothing inside.
ZIP - Flat
A ZIP archive — 3 files at the root, no directories. Deterministic (fixed member timestamps) and safe to extract anywhere.
ZIP - Many Small Files
A ZIP archive — 100 tiny files for throughput testing. Deterministic (fixed member timestamps) and safe to extract anywhere.
ZIP - Nested Folders
A ZIP archive — files organised into data/ and docs/ subfolders. Deterministic (fixed member timestamps) and safe to extract anywhere.
ZIP - Unicode Filenames
A ZIP archive — UTF-8 filenames: accents, Japanese, emoji. Deterministic (fixed member timestamps) and safe to extract anywhere.
Compression
LZ4 — Single File
A text file compressed with the LZ4 frame format (.lz4) — the container-free codec on its own — for testing LZ4 decompression and codec detection.
ZST — Zstandard Single File
A text file compressed with Zstandard (.zst) — the container-free codec on its own — for testing zstd decompression and codec detection.
Tarball
TAR - Uncompressed
A uncompressed USTAR of a small source tree — for testing tar extraction and the TAR container. Member timestamps are fixed for reproducibility.
TAR.BZ2 - Bzip2 Tarball
A bzip2-compressed tar of a small source tree — for testing tar extraction and the TBZ2 container. Member timestamps are fixed for reproducibility.
TAR.GZ - Gzip Tarball
A gzip-compressed tar of a small source tree — for testing tar extraction and the TGZ container. Member timestamps are fixed for reproducibility.
TAR.XZ - XZ Tarball
A xz/LZMA-compressed tar of a small source tree — for testing tar extraction and the TXZ container. Member timestamps are fixed for reproducibility.
Web
WARC — Web Archive
A minimal WARC 1.0 web archive with a warcinfo record and an HTTP response record capturing a small HTML page — for testing WARC parsers and web-archive tooling.
