Disk Management in Windows helps you perform advanced storage tasks like initializing a new drive and extending or shrinking volumes. To open Disk Management, right-click (or long-press) the Start button and select Disk Management.

Storage Spaces helps protect your data from drive failures and extend storage over time as you add drives to your PC. You can use Storage Spaces to group two or more drives together in a storage pool and then use capacity from that pool to create virtual drives called storage spaces.

Windows will prompt you to free up disk space or use external storage to temporarily extend the storage on your PC. If you use an external storage device, Windows won’t need as much free space on the system drive as it temporarily uses your external storage.

When Windows sends this notification, select the message or go to Start > Settings > System > Storage > Manage disks and volumes, then select Properties for the problematic disk to see additional details. For example:

OneDrive Files On-Demand helps you access all the files in your cloud storage in OneDrive without having to download them and use storage space on your computer.
