I think you're misunderstanding how OneDrive works.
And the point I was getting at is that there's no need to move the files at all...
Sure, if I scrap the way I have everything setup, and convert everything to offsite OneDrive storage.
I have terabytes of videos on a Windows Server in the back room that my XBMC box accesses to view them on the TV. I want some of those videos on my phone. I don't want to have to walk back there and plug the phone in with USB, I don't want to setup OneDrive on the Windows Server machine. How do you suggest I accomplish that? Also, my ISP throttles speed and charges extra fees if I exceed a specific amount of gigabytes per month.
That's two use cases for the feature, if you're keeping count.
1. Corporate policies prevent cloud storage, user is outside where no computer is readily available but has phone in pocket with preloaded Office software and connection to WiFi.
2. Personal media that users stubbornly already have on local network, ISP bills for overages, users don't want to waste their bandwidth to get local files from one device to another by syncing them to a cloud service.
