Enable syncing the data from the external hard disk to OneDrive for Business.
I am aware of the new sync folder has been created in the "C-drive" when the initial synchronization is performed on OneDrive for Business by default. Also, it takes the time to copy the items from the external hard disk to the OneDrive for Business synchronization folder manually by D&D.
I hope the feature will be improved to sync the data from the external hard disk to OneDrive for Business directly in order to saving the capacity for the local computer through the user synchronized the items to OneDrive for Business. (without copying process or else)
Thank you for your continued support.
