• Use the following command to track a specific file:

Uploading Large Files

After tracking, you can add and commit large files to your repository as you normally would with Git. Git LFS will automatically handle the file transfer to the LFS server.

Code:

“**Note:** The file content itself is not stored in the Git repository; instead, it’s managed by Git LFS.”

Cloning a Repository with LFS Files

When cloning a repository that uses Git LFS, ensure that you have Git LFS installed on your system. Git LFS will automatically download large files during the cloning process, making it seamless for contributors.

Best Practices for Git LFS

File Types Suitable for Git LFS

Not all files should be stored using Git LFS. Reserve it for binary files, such as:

• Images (JPEG, PNG, GIF);
• Videos (MP4, AVI);
• Audio (MP3, WAV);
• Large datasets (CSV, JSON).

For text-based files, Git’s standard version control is sufficient.

.gitattributes Configuration

You can fine-tune Git LFS behavior by configuring the .gitattributes file. Here’s an example:

This configuration tells Git to treat all .jpg files as LFS objects.

Git LFS vs. Standard Git
