Microsoft Graph Storage

Microsoft Graph storage typically refers to the storage capabilities exposed through Microsoft Graphprimarily OneDrive and SharePointvia the Files and Drives APIs. It lets apps programmatically store and manage files and folders, upload and download (including large-file upload sessions), track changes with delta queries, generate thumbnails, search, and share content with rich permission controls. For app-specific data, developers can use the users OneDrive appFolder as a private per-app space, and attach custom metadata to Microsoft 365 entities using open or schema extensions. All of this is accessed through the Microsoft Graph REST API and SDKs with delegated or application permissions, inheriting Microsoft 365 security, compliance, and auditing.
