Understanding the Use of Git LFS (Large File Storage)

Git Large File Storage (LFS) is an open-source Git extension that optimizes the process of working with large files in a Git repository. Understanding how to use Git LFS effectively can increase the efficiency of your programming projects, especially when dealing with substantial file types.

How Git LFS works is that it replaces these large files such as audio samples, videos, datasets, and graphics with text pointers inside Git, while storing the file contents on a remote server like GitHub.com or GitHub Enterprise.

By using Git LFS, users can clone or pull from the repository without downloading all file versions from the history as it downloads only the versions of large files referenced by commits in the current checkout.

Practical Applications of Git LFS

Git LFS has several practical uses, mainly revolving around managing large files in Git repositories. Some popular uses include creating high-definition game assets, storing large datasets for data analysis or machine learning projects, or managing large multimedia files for web design projects.

Take, for instance, a game development project where designers are working with multiple high-definition 3D assets. These files could potentially be several gigabytes in size, making them difficult to work with in a standard Git repository. Using Git LFS, these large files are more effectively managed, improving the work efficiency of the development team.

Best Practices for Using Git LFS

While Git LFS solves a significant problem of dealing with large data, there are several best practices to follow:

• Keep track of storage use - Storing large files can quickly consume a repository's allocated storage, especially if many large files are frequently modified. So it's important to monitor and manage the storage used in your LFS.

• Use it only when necessary - Standard Git can handle many smaller files just fine. Use LFS when your files are too large for standard Git to handle efficiently (usually when individual files exceed 100MB in size).

• Avoid storing sensitive information in LFS - Just like regular Git, it's not advisable to store sensitive information or data, such as passwords or confidential data, in Git LFS. Although it is possible to encrypt data before putting it into LFS, it's best to avoid including such sensitive information in the repos at all.

By understanding Git LFS and the best practices for using it, programming teams can manoeuvre effectively and efficiently when working with repositories that contain large files.
