Microsoft OneDrive is a file hosting service and synchronization service operated by Microsoft as part of its web version of Office. First launched in August 2007, OneDrive allows users to store files and personal data like Windows settings or BitLocker recovery keys in the cloud, share files, and sync files across Android, Windows Phone, and iOS mobile devices, Windows and macOS computers, and the Xbox 360 and Xbox One consoles. Users can upload Microsoft Office documents directly to OneDrive. OneDrive offers 5 GB of storage space free of charge, with 50 GB, 1 TB, and 5 TB storage options available either separately or with Office 365 subscriptions.
