Google Drive is the cloud storage and file sharing service of Google, part of Google Workspace. Cloud storage means that files are kept on the provider's servers instead of on one computer, so they can be opened from any device and shared with other people.
A user uploads files from the browser, from the Drive apps for Android and iOS, or through Drive for desktop, which syncs a computer's files to the cloud. Drive opens and edits Google Docs, Sheets and Slides, Microsoft Office files and PDFs, and gives access to more than 100 other file types. Sharing uses permissions (edit, comment, view) and can set expiration dates. Business plans add shared drives that belong to a team instead of one person, electronic signatures, ransomware detection and data loss prevention rules. Gemini, Google's AI assistant, answers questions about the stored files with cited answers. Storage ranges from 15 GB to 5 TB per user.
Drive is a hosted service. Businesses get it as part of a Google Workspace subscription, priced per user per month, with a 14-day free trial.
