What this script does

Published: April 2026

TorrentZip (TZ) is a command‑line utility that creates deterministic ZIP archives. Determinism means that given the same set of input files, TZ will always produce a byte‑identical ZIP file regardless of: esko+artios+cad+v120+torrentzip+new

| Variable | Standard ZIP Behavior | TorrentZip Behavior | |---|---|---| | File order | Depends on OS enumeration (often nondeterministic) | Sorted alphabetically, then by case‑insensitive path | | Timestamps | Stored as local file modification time | Normalised to a fixed epoch (e.g., 2000‑01‑01 00:00:00 UTC) | | Permissions & extra fields | Preserved verbatim (may differ by filesystem) | Stripped or standardised | | Compression metadata | Varies with library version and thread count | Fixed compression level (-9) and dictionary | What this script does Published: April 2026

Because the output is predictable, any change in the source files results in a different hash (SHA‑256, MD5, etc.). This property is essential for: TorrentZip (TZ) is a command‑line utility that creates
