You can add OneDrive to the File Explorer in Windows 10 by connecting your OneDrive account to the computer.

Using a little-known feature of Windows 10 and 11, we can automatically designate a specific drive letter to Microsoft OneDrive at startup every time we boot up our PC.

If OneDrive shared folders are not showing in File Explorer on your Windows 11/10 PC, check OneDrive sync settings, Reset OneDrive, etc.

The latest Windows 11 preview build from the Dev and Beta channel contains a hidden change Microsoft did not announce: the ability to set File Explorer open OneDrive on launch by default.
