When to Use Git LFS: Managing Large Files in Git

Use git lfs when your project includes large files like images, videos, or datasets that slow down normal git operations. It stores large files outside the main repository, keeping your repo fast and lightweight.

How It Works

Git LFS (Large File Storage) works like a smart assistant for your Git repository. Instead of saving big files directly inside your repo, it replaces them with small pointers. These pointers tell Git where to find the actual large files stored separately.

Think of it like storing heavy boxes in a nearby warehouse instead of your small car trunk. Your car (Git repo) stays light and easy to drive, while the boxes (large files) are safely kept nearby and fetched only when needed.

Example

This example shows how to track a large file type (like .psd Photoshop files) with Git LFS and commit it.

bash

git lfs install
git lfs track "*.psd"
git add .gitattributes
# Add your large file
git add design.psd
git commit -m "Add large design file with Git LFS"

Output

Git LFS initialized.
Tracking *.psd
[master abc1234] Add large design file with Git LFS

When to Use

Use Git LFS when your project has large files that make cloning, fetching, or pushing slow. Common cases include:

• Game assets like textures and models
• High-resolution images or videos
• Datasets for machine learning
• Audio files for podcasts or music projects

It helps keep your repository size manageable and speeds up collaboration by avoiding repeated downloads of big files.

Key Points

• Git LFS replaces large files with lightweight pointers in your repo.
• Large files are stored separately on a Git LFS server or cloud.
• Improves performance by reducing repo size and speeding up Git operations.
• Requires Git LFS installed on all collaborators' machines.
• Best for projects with frequently changing large binary files.

Key Takeaways

Use Git LFS to manage large files that slow down normal Git operations.

Git LFS stores big files outside the main repo, keeping it fast and small.

Track file types with git lfs track to enable large file handling.

Ideal for projects with images, videos, audio, or datasets.

All team members must have Git LFS installed to work with large files.
