Microsoft OneDrive is a file hosting service operated by Microsoft. First launched in August 2007, it enables registered users to share and synchronize their files. OneDrive also works as the storage backend of the web version of Microsoft Office.
Most OneDrive users get access as a part of a Microsoft 365 subscription, which includes Microsoft Office and 1TB of OneDrive storage space. But you can also get a free OneDrive account with 5GB of space. OneDrive lets you keep files that you create and store on your computer in sync with the cloud.
