About

HatchZip is an open-source archive extractor for low-disk-space workflows, licensed under MIT or Apache-2.0. It extracts pieces and progressively truncates the source archive, reusing released space. It supports ZIP, 7z, tar, tar.gz and split archives, with a desktop interface and the hatchzip/hz CLI. Use hatchzip check to inspect space requirements without changes; interrupted extraction can resume.

Important: extraction consumes the original archive. Keep a separate backup for irreplaceable data and consider --verify-first. Do not delete .hatchzip or .hatchzip-tail progress files mid-extraction. RAR is not supported; a large solid 7z block may still require substantial free space. APFS snapshots can prevent space reclamation; hole-punching savings on APFS are not verified.

Official macOS downloads include separate Apple silicon and Intel DMGs. The packaging Info.plist declares macOS 11.0 minimum; this is a declared requirement, not our runtime test. Drag the app to Applications. The app is ad-hoc signed, not Developer ID signed or notarized; review the source and Gatekeeper warning before deciding whether to allow it. Release checked: v0.1.2. No benchmark or extraction safety test was performed by OpenNavo.

Security

This release fixes GHSA-446w-m5mg-2f58 (High), reported by @Valcyle. Update if you open archives that came together with other files.

HatchZip keeps two progress files next to an archive while it extracts, <archive>.hatchzip and <archive>.hatchzip-tail, so a stopped extraction can resume. Before this release, progress files planted next to an archive, for example inside a downloaded bundle, could make a resume shrink or delete other files, or create links outside the output folder. A resume now uses them only when:

  • every volume they name is one of that archive's own volumes, and none of them is a link;
  • every link they name is inside the output folder, and no link already in the output folder lies on the way;
  • the output folder is the default one next to the archive, a folder chosen on this computer, or the folder named again with -o.

Anything else is refused before a file is changed. Folders you choose with -o or in the app are recorded in your user profile, so a resume on the same computer works as before. To continue on another computer, name the folder again with -o.

Also published: GHSA-6rh6-c2xg-gj28 (High), reported by Benjamin Kincses (@Dextheking1), a link entry below another link entry. It was already fixed in 0.1.3.

Changes

  • hatchzip restore accepts -o to name the output folder of the extraction it undoes.
  • HatchZip refuses to extract into a default output folder that is a link, and to change an archive volume that is a link.
  • CodeQL analysis of the Rust code and the workflows runs on every change.

Downloads

Every file comes with a SHA-256 checksum and signed build provenance. To check a download:

gh attestation verify HatchZip-x64.msi --repo xevrion/hatchzip

Checksums and VirusTotal links for every file: Verify your download.

Package managers: brew install xevrion/tap/hatchzip (command line), brew install --cask xevrion/tap/hatchzip (app), and scoop bucket add xevrion https://github.com/xevrion/scoop-bucket followed by scoop install xevrion/hatchzip.

RAR archives are decoded by UnRAR, under its own license, included with every download.
