Downloads Organizer

Automatically organize and clean up your downloads folder with intelligent file categorization, duplicate detection, and storage optimization.

Overview

Transform a chaotic downloads folder into a well-organized, searchable archive by:

• Categorizing files - Organize by type (documents, images, videos, installers, etc.)
• Removing duplicates - Detect and eliminate duplicate files
• Cleaning old files - Remove outdated installers and temporary files
• Generating reports - Provide detailed analysis of storage usage
• Scheduled cleanup - Set up automated maintenance

Basic Workflow

Cleanup Strategies

Time-Based Cleanup

Installers:

• Remove *.dmg, *.pkg files older than 60 days
• Keep only recent installers (last 2 months)

Temporary Files:

• Remove *.tmp, *.temp, *.cache files
• Clean ~/.Trash contents

Empty Folders:

• Remove directories with 0 files
• Remove directories older than 90 days with < 5 files

Duplicate Detection

Find duplicates by:

• File name - Exact name match
• File size - Same size (quick filter)
• Hash comparison - MD5/SHA256 for exact duplicates

Action:

python scripts/organizer.py --find-duplicates

Keep strategy:

• Keep newest file
• Keep file with shortest path
• Ask user for conflicts

Large File Analysis

Identify space hogs:

python scripts/organizer.py --large-files --min-size 100MB

Output:

📦 Large Files (>100MB):
1. alma-0.0.204-mac-arm64.dmg - 248 MB
2. recording_2026-01-10_23-22-53.mp4 - 12 MB
3. generated-1768282547017.png - 25 MB

Automated Maintenance

Schedule Cleanup

Set up cron job for automatic cleanup:

# Run cleanup every Sunday at 2 AM
0 2 * * 0 cd ~/Downloads && python scripts/organizer.py --cleanup

# Run organization daily at 9 AM
0 9 * * * cd ~/Downloads && python scripts/organizer.py --organize

Automated Rules

Define custom rules in config/rules.yaml:

patterns:
  - pattern: "*_recording_*.mp4"
    destination: Videos/Recordings/
    keep_days: 30

  - pattern: "generated-*.png"
    destination: Images/Generated/
    keep_days: 7

  - pattern: "Screenshot*.png"
    destination: Images/Screenshots/
    keep_days: 30

Configuration

Settings File

Create ~/.downloads-organizer/config.yaml:

downloads_dir: ~/Downloads

  auto_categorize: true
  respect_existing_folders: true
  create_missing_folders: true

Best Practices

Organization

✅ DO:

• Organize regularly (daily or weekly)
• Use consistent folder structure
• Keep recent installers accessible
• Archive important files to permanent locations

❌ DON'T:

• Wait until downloads folder is huge
• Mix unrelated file types
• Delete files without reviewing
• Keep old installers "just in case"

Cleanup

✅ DO:

• Set appropriate age thresholds
• Review duplicates before deleting
• Check large files before cleanup
• Backup important files first

❌ DON'T::

• Delete files blindly
• Set too aggressive cleanup
• Ignore duplicate warnings
• Skip backup checks

Performance

✅ DO:

• Schedule cleanup during low activity
• Use dry-run first
• Monitor disk space after cleanup
• Keep logs for troubleshooting

❌ DON'T:

• Run cleanup while downloading
• Organize during file transfers
• Disable safety checks
• Ignore error messages

Troubleshooting

File Move Conflicts

Problem: "File already exists" error

Solution:

python scripts/organizer.py --organize --handle-conflicts ask

Options:

• ask - Prompt for each conflict
• skip - Skip conflicting files
• overwrite - Overwrite existing files
• rename - Add timestamp to new files

Permission Errors

Problem: "Permission denied" when moving files

Solution:

# Fix permissions
chmod -R u+rw ~/Downloads

# Run with sudo (last resort)
sudo python scripts/organizer.py --cleanup

Slow Performance

Problem: Organization takes too long

Solution:

# Exclude large directories
python scripts/organizer.py --exclude "Projects/,Backups/"

# Use parallel processing
python scripts/organizer.py --parallel --workers 4

# Skip hash comparison for duplicates
python scripts/organizer.py --find-duplicates --quick

Safety Features

Backup Before Cleanup

Always create backup before major cleanup:

python scripts/organizer.py --backup --dest ~/Downloads-backup

Undo Functionality

Roll back changes:

python scripts/organizer.py --undo --from ~/Downloads-backup

Confirmation Prompts

Confirm destructive actions:

python scripts/organizer.py --cleanup --confirm

Logging

Detailed logging for audit:

python scripts/organizer.py --organize --log-level debug --log-file organizer.log
