Archive Extractor

Extract archives using 7-Zip CLI.

Prerequisites

  • 7-Zip must be installed and in PATH: 
    # Windows - typically installed at:
# C:\Program Files\7-Zip\7z.exe

# Verify
7z --help

Quick Start

# Extract archive to subfolder (archive-name/)
python scripts/archive_extract.py archive.zip

# Extract to specific location
python scripts/archive_extract.py archive.rar -o ./extracted

# JSON output with file list
python scripts/archive_extract.py course.7z --json

# Extract with password
python scripts/archive_extract.py protected.zip --password secret

Output

Human-readable:

Archive: course_materials.zip
Extracting to: ./course_materials/

Extracted 15 files:
  course_materials/lesson1.pdf
  course_materials/lesson2.docx
  course_materials/images/diagram.png
  ...

JSON:

{
  "source": "course_materials.zip",
  "destination": "./course_materials",
  "file_count": 15,
  "files": [
    {"path": "course_materials/lesson1.pdf", "size": 102400},
    {"path": "course_materials/lesson2.docx", "size": 51200}
  ],

CLI Reference

python scripts/archive_extract.py ARCHIVE [OPTIONS]

Arguments:
  ARCHIVE               Archive file to extract

Options:
  -o, --output DIR      Output directory (default: archive name as folder)
  -j, --json            Output as JSON with file list
  -p, --password PWD    Archive password
  --flat                Don't create subfolder, extract directly
  --overwrite           Overwrite existing files
  -q, --quiet           Suppress progress output

Pipeline Integration

After extraction, pass file list to file-router for recursive processing:

# Extract and get file list
FILES=$(python archive_extract.py course.zip --json | jq -r '.files[].path')

# Route each extracted file
for f in $FILES; do
    python file_router.py "$f" --json
done

Extraction Behavior

  • Default: Creates subfolder named after archive (without extension)
    • course.zip extracts to ./course/
  • With --flat: Extracts to current directory or specified output
  • Nested archives: Not automatically extracted (process returned file list)
