In Google Workspace (formerly G Suite), Cloud File Server refers to the use of Google Drive as a file server. Google Drive is a cloud storage service that allows you to store and access your files from anywhere, on any device.
To use Google Drive as a file server, you can install the Google Drive app on your computer and sync your files between your computer and the cloud. This allows you to access your files from your computer just like you would with a traditional file server, but with the added benefits of being able to access your files from anywhere and being able to easily collaborate with others.
You can also use Google Drive as a file server through the web interface or through apps on your mobile devices. This allows you to access your files from anywhere and collaborate with others in real-time.
