When you first access OneDrive from your Windows computer, OneDrive will automatically sync to your computer. You will thereafter see a little blue cloud icon in your system tray (bottom right of desktop). If you click on the icon, you can access a copy of your OneDrive files. The status column tells you whether the files have been downloaded to your computer (green tick) or are only in the cloud.
