## Description

VFSForGit is a virtualization layer and enterprise scaling solution for Git. It enables the management of massive codebases by downloading repository objects on demand, allowing users to interact with extreme-scale repositories without requiring a full local clone.

The project optimizes performance by limiting the scope of Git commands to files currently accessed by the user. It utilizes a virtual file system projection to present a complete directory tree while keeping file data remote until it is specifically requested.

The system employs virtualization techniques including deferred content materialization and on-demand object hydration. These capabilities work alongside selective history loading and sparse checkout integration to reduce local disk space and network overhead.
