This article describes how to access and configure Microsoft’s OneDrive for Business to sync files and folders between the cloud and your local device (desktop, laptop, etc.).
OneDrive allows you to sync files and folders between your local device and the cloud for accessibility from any location (workstation, mobile device, Microsoft 365 website, etc.). If any files are added, edited, and/or deleted in your locally stored OneDrive folder, then that change will be reflected in OneDrive Online; the opposite direction is also true. You may also access your synced files in the Windows File Explorer when offline. Once your device connects to a network, any changes made by you or any others that have access to the file will be synced automatically.
Microsoft provides instructions at Sync files with OneDrive in Windows - Microsoft Support.
After adding your desired account, you may change which folders sync on your computer.
