Google Drive Shell Extension is a Shell Namespace Extension for Microsoft Windows. It creates a virtual folder on My Computer, mirrored in the user's home directory, that allows the user to interact with his Google Drive account transparently through Windows Explorer. This includes "File Open" and "Browse" commands from within other Windows applications, etc. It connects to Google Drive using the Google Drive Proxy service.The main feature of the project is that syncronization is performed only as needed. Instead of holding the entire contents of your Google Drive folder on disk, it only keeps what it needs. When you open or copy files it will download them. It will then upload any changes you make locally to keep the folders in sync. This means that your content is not available while offline.
