📁 Git LFS = Large File Storage

Git repos get bloated. Git LFS stores large files efficiently. Images, videos, binaries — keep repo fast.

📝 Git LFS Setup

# Install Git LFS
# macOS
brew install git-lfs

# Linux
sudo apt install git-lfs

# Windows
# Download from https://git-lfs.github.com

# Initialize LFS
git lfs install

# Track file types
git lfs track "*.psd"
git lfs track "*.png"
git lfs track "*.jpg"
git lfs track "*.mp4"
git lfs track "*.zip"
git lfs track "*.pdf"

# Track specific files
git lfs track "assets/logo-large.png"

# View tracked patterns
git lfs track

# .gitattributes (auto-generated)
*.psd filter=lfs diff=lfs merge=lfs -text

# Commit LFS files
git add .gitattributes
git add *.psd
git commit -m "Add large files with LFS"
git push origin main

# Migrate existing files to LFS
git lfs migrate import --include="*.psd,*.png"

# Migrate with history rewrite
git lfs migrate import --include="*.psd" --everything

🎯 Advanced LFS Commands

export GIT_LFS_STORAGE=100MB

# Check LFS storage usage
git lfs quota

# Debug LFS operations
GIT_TRACE=1 git push origin main
GIT_CURL_VERBOSE=1 git lfs fetch

# LFS with SSH

💡 LFS Best Practices

• Only use for large files (over 1MB)
• Set .gitattributes early
• Monitor LFS storage limits
• Use LFS in CI/CD pipelines
• Consider storage costs
