A Microsoft file hosting and synchronization service.
Hi Tanvir-Hossain,
I’m glad to offer some help.
According to your description, you would like to add, backup and sync any local folders to OneDrive, if so, based on my experience, currently we can move know folders (Desktop, Documents, Pictures, Screenshots, and Camera Roll) to OneDrive to help improve the work efficiency.
More details please seeRedirect and move Windows known folders to OneDrive
If you want to sync all folders in other drive to OneDrive, I’m afraid this is the limit of OneDrive, but I have searched a lot, if you are willing, you may create MKlink to sync any directory to your OneDrive.
You can refer the below articles:
