File Organization Guide

Organize files, find duplicates, and maintain clean folder structures.

When to Use

• Downloads folder is chaotic
• Can't find files (scattered everywhere)
• Duplicate files taking up space
• Folder structure doesn't make sense
• Starting a new project structure
• Cleaning up before archiving

Analysis Commands

# Overview of directory
ls -la [directory]

# Count file types
find [directory] -type f | sed 's/.*\.//' | sort | uniq -c | sort -rn

# Largest files
du -sh [directory]/* | sort -rh | head -20

# Files modified this week
find [directory] -type f -mtime -7

Finding Duplicates

# By hash (exact duplicates)
find [directory] -type f -exec md5sum {} \; | sort | uniq -d

# By name
find [directory] -type f -printf '%f\n' | sort | uniq -d

# By size
find [directory] -type f -printf '%s %p\n' | sort -n | uniq -D -w 10

Organization Workflow

1. Analyze - Review current structure
2. Plan - Propose new structure
3. Confirm - Get user approval
4. Execute - Move files systematically
5. Summarize - Report changes

Execution Commands

# Create structure
mkdir -p "path/to/new/folders"

# Move files
mv "old/path/file.pdf" "new/path/file.pdf"

# Batch move by extension
find . -name "*.pdf" -exec mv {} Documents/ \;

Best Practices

Folder Naming

• Clear, descriptive names
• Avoid spaces (use hyphens)
• Use prefixes for ordering: 01-current, 02-archive

File Naming

• Include dates: 2024-10-17-meeting-notes.md
• Be descriptive
• Remove download artifacts: file (1).pdf → file.pdf

When to Archive

• Not touched in 6+ months
• Completed work for reference
• Old versions after migration
• Files you're hesitant to delete

Maintenance Schedule

Important Rules

• Always confirm before deleting
• Log all moves for undo
• Preserve modification dates
• Stop and ask on unexpected situations
