## Built for difficult archive jobs

01

### Nested archives

Continue through multiple archive layers with bounded depth and clear output folders.

02

### Split archives

Recognize supported multipart sets and avoid processing every part as a separate archive.

03

### Visible progress

Report the current archive, phase, layer, elapsed time, and completion evidence.

04

### Cross-platform

Reviewed workflows for Linux, macOS, and Windows with platform-specific packages.

05

### Source preservation

Keep source archives by default and avoid silent overwrites or unknown executable launches.

06

### Batch organization

Handle files, folders, absolute or relative paths, and matched inputs consistently.

## Install and use the Skill

The installer audits the directory, stages it atomically, and backs up an existing installation when --replace is used.

1. 1

   Download the complete Skill ZIP and compare its SHA-256 below.
2. 2

   Extract it to a temporary folder; keep the top-level folder named unpack-flow.
3. 3

   Run the bundled install\_local.py with --replace. It creates a backup before replacing an older copy.
4. 4

   Restart Codex, then ask naturally for an archive, folder, or batch to be unpacked.

Linux / macOS

` python3 unpack-flow/scripts/install_local.py unpack-flow --replace `

Windows

` py unpack-flow\scripts\install_local.py unpack-flow --replace `

Expected result: $CODEX\_HOME/skills/unpack-flow/SKILL.md exists together with scripts, references, assets, and tools.

Example request

“Use UnpackFlow to inspect and unpack the archives in ./downloads. Preserve the originals and keep reporting progress.”

## Safety defaults

Extraction writes files, so review the target and available disk space first.

- No automatic deletion of source archives
- No overwrite unless you explicitly choose it
- No execution of unknown self-extracting payloads
- Path and archive checks before website mirroring
- Fixed-version downloads with published digests

## Formats and runtime boundaries

ZIP, TAR families, 7z, RAR and other formats depend on the included or detected extractor for your platform. Password-protected archives require a password you are authorized to use. UnpackFlow does not bypass DRM, passwords, operating-system warnings, or access controls.

## A live GitHub-backed download

GitHub Releases is the only version source. The website checks stable releases on a schedule, rejects unsupported major versions, downgrades, missing assets, checksum failures, unsafe archive paths, and same-tag digest changes, then atomically promotes the verified local mirror.
