Sample Archives test files

What are archive test files?

ZIP, TAR, GZIP and 7z files built to exercise extraction code: valid archives in several layouts, plus the cases a safe extractor must refuse, including Zip Slip paths, absolute paths, a decompression bomb, deep nesting and a corrupt central directory.

File	Format	Size	What it catches
`absolute-path.zip`	ZIP	161 bytes	Archive whose entry name is an absolute path (/tmp/qa-absolute.txt).
`corrupt-central-directory.zip`	ZIP	219 bytes	Valid local file headers, but the central directory signature is overwritten with garbage.
`empty.zip`	ZIP	22 bytes	A structurally valid ZIP containing zero entries (22-byte end-of-central-directory only).
`mixed-content-50mb.zip`	ZIP	40.0 MB	Realistic ~50 MB archive mixing incompressible binary blobs with highly compressible text.
`modest-zip-bomb.zip`	ZIP	996 KB	A ~1 MB archive that expands to roughly 1 GB: ten entries of 100 MB of zeroes each. Deliberately modest - this is not a 42 KB / 4.5 PB bomb.
`nested-10-deep.zip`	ZIP	1.2 KB	A ZIP containing a ZIP containing a ZIP, ten levels down, with a text file at the centre.
`single-file.gz`	GZIP	146 bytes	A single gzip-compressed text file (not a tar), with the original filename in the header.
`stored.7z`	7z	303 bytes	A valid .7z archive holding three files, including one in a subdirectory. Entries use the Copy codec, so they are stored rather than compressed.
`unicode-entry-names.zip`	ZIP	563 bytes	Entries named in Japanese, Arabic, Russian and emoji, with the UTF-8 flag (bit 11) set correctly.
`valid-flat.zip`	ZIP	376 bytes	Three deflated text files at the archive root, no directories.
`valid-nested-dirs.zip`	ZIP	390 bytes	Archive with entries five directory levels deep.
`valid.tar`	TAR	4.0 KB	A USTAR tar archive with three files, including one in a subdirectory.
`valid.tar.gz`	TAR+GZIP	188 bytes	The gzip-compressed form of a tar archive - the ubiquitous .tar.gz.
`zip-slip-traversal.zip`	ZIP	357 bytes	Archive containing an entry named ../../../../tmp/qa-zip-slip.txt. The payload is a harmless text marker, but the path escapes the extraction directory.
