A Microsoft file hosting and synchronization service.
Hi, I'm John! I will help you with this.
You can move the OneDrive folder to the D: drive without losing your synced files.
- Right-click the OneDrive cloud icon near the clock
- Select Settings
- Go to Account > Unlink this PC
- Sign in again
- During setup, select Change location
- Choose a folder on the D: drive
After that, OneDrive will sync to the new location.
Before moving it, how much free space is left on your C: drive and D: drive?
Also, are you trying to move only the OneDrive folder, or do you also want to free up space by making files online-only?
