OneDrive is a file hosting and synchronization service developed by Microsoft. It allows you to store personal data and files, such as photos, documents, and pictures, and enables you to sync system settings, visual customizations, themes, app settings, browsing history, and even passwords. OneDrive is a cloud service that connects you to all your files, letting you store and protect your files, share them with others, and get to them from anywhere on all your devices. When you use OneDrive with an account provided by your company or school, its sometimes called "OneDrive for work or school". OneDrive for home is online personal storage that you get when you set up a Microsoft account to use services such as Outlook.com or Xbox.

Some key features of OneDrive include:

• Storage: Everyone with a Microsoft account gets 5GB of free storage, with 50GB for $2/month. Many Office 365 subscription levels provide 1TB (1,024GB) of OneDrive storage, free, for as long as youre an Office 365 subscriber.

• Syncing: OneDrive enables you to sync your files to the cloud services, but its free storage space is limited and small.

• Accessibility: OneDrive lets you get to your files from any device connected to the Internet.

Overall, OneDrive is a cloud-based storage service that allows you to store and access your files from anywhere, on any device.
