Why Git LFS for large files? - Purpose & Use Cases

The Big Idea

What if your huge project files could stay fast and light without losing any data?

The Scenario

Imagine you are working on a project with huge images or videos. You try to save them directly in your Git repository like normal files.

The Problem

Saving big files directly makes your repository very slow and heavy. Every time you clone or pull, it takes a long time and uses lots of space. Mistakes happen when files get corrupted or versions get mixed up.

The Solution

Git LFS stores only small pointers in your repository and keeps the big files separately. This keeps your project fast and clean while still tracking large files easily.

Before vs After

✗ Before

git add big_video.mp4
git commit -m "Add big video"

✓ After

git lfs track "*.mp4"
git add .gitattributes big_video.mp4
git commit -m "Add big video with LFS"

What It Enables

You can work with large files smoothly without slowing down your whole project or wasting space.

Real Life Example

A game developer stores huge textures and sound files using Git LFS, so the team can share updates quickly without waiting hours for downloads.

Key Takeaways

Large files slow down normal Git repositories.

Git LFS keeps big files outside the main repo, using pointers instead.

This makes working with big files fast and easy.
