About Onedrive
OneDrive is Microsoft's cloud storage and file synchronization service, deeply integrated into Windows 10/11, Microsoft 365, and the broader Microsoft ecosystem. Launched in 2007 (as SkyDrive), OneDrive is bundled with every Windows installation and automatically syncs the Desktop, Documents, and Pictures folders for users who opt in. Free storage is 5GB; Microsoft 365 Personal ($69.99/year) includes 1TB of OneDrive storage alongside Word, Excel, PowerPoint, and Outlook. Microsoft 365 Family ($99.99/year) extends 1TB to up to 6 users. For businesses, OneDrive for Business is included in all Microsoft 365 Business plans (starting $6/user/month), providing 1TB per user with SharePoint integration for team document libraries. OneDrive's integration advantage is unmatched for Windows and Office users: files open directly in Word/Excel, Teams integrates file storage natively, and Windows Search indexes OneDrive content. Version history, real-time co-authoring in Office apps, and Personal Vault (extra-secure folder with two-factor authentication) round out the feature set. For non-Microsoft users on macOS or mobile, OneDrive works well but loses its key integration edge. OneDrive competes primarily on value — for existing Microsoft 365 subscribers, there is no cost reason to use a competing service.
Frequently Asked Questions
Is OneDrive included with Windows?
OneDrive app is pre-installed on Windows 10 and 11 and offers 5GB free storage. The 1TB storage expansion requires a Microsoft 365 subscription. The OneDrive sync client runs automatically in the background on Windows.
Can I use OneDrive without Microsoft 365?
Yes. A free Microsoft account gives you 5GB of OneDrive storage accessible via web and the OneDrive app on any platform. Microsoft 365 subscriptions increase storage to 1TB and add Office app access.
Is OneDrive secure?
OneDrive uses AES 256-bit encryption at rest and TLS in transit. Personal Vault adds two-factor authentication for sensitive files. For enterprise security requirements, SharePoint and Box offer more granular compliance controls.
