## What it is
VFS for Git is a virtual file system for Windows that lets Git repositories of enterprise scale behave like normal working directories, downloading objects on demand and speeding up Git operations on huge monorepos. Microsoft now recommends its successor, Scalar, for new deployments.

## Use cases
- clone and work with a massive git monorepo without downloading everything
- speed up git status and checkout on a huge repository
- virtualize a git working directory on windows
- enable git at enterprise scale
- only fetch files from a repo as they are needed

## When to choose
- you are on Windows and must work with an extremely large Git repository
- you already have an existing VFS for Git deployment and need to maintain it

## When to avoid
- you are starting a new large-repo deployment - use Scalar instead
- you are on macOS or Linux - this is Windows-only
- your repositories are small enough that regular Git performs fine

## Facets
- artifact type: application
- maturity: maintenance
- function: version-control, file-system, developer-tools
- domain: version-control, developer-tools, windows
- platform: windows, cli
- tags: git, virtual-file-system, monorepo, large-repositories, vfs
