Thanks.
My use case is to transfer files created on one machine (in the field) to another machine in my office. When I install OneDrive on the field machine, it gets busy synching 40,000 files to itself, and using up my cellular modem subscription. Would be great to specify the folder that I want to sync prior to OneDrive automatically syncing them all. After installation, I see all the folders in the directory in Windows Explorer on my field machine. This takes an hour each time.
Putting it another way, I'm linking to an existing cloud storage OneDrive account, and don't want the entire contents on my local machine.
