The Google Drive FAQ
What is Google Drive?
Google Drive is a way to store your files on Google’s servers, or “in the cloud.” If you run the free Google Drive application, then you get a folder on your computer (Windows or OSX) that looks just like a directory on your hard disk that you can drag your files in to. Anything stored in that folder is kept on your hard disk and also copied to your account in the cloud. You can access those files from drive.google.com or from other computers, including mobile devices.
Google Drive is also the new name for Google Docs, which is Google’s suite of Web-based productivity tools — its word processor, spreadsheet, and presentation app. Documents you create using these tools now show up in your Google Drive. Sort of.
