A Microsoft file hosting and synchronization service.
Still nothing from M$............
I pay to get extra storage on OneDrive, and still don't have the option to get rid of this feature that I don't use and that through design interrupts file syncing on a daily basis. Having to mess about with restores is not really an option when the whole point of my using One drive is to sync my work so that I can access it on any of my workstations from anywhere, mobile or desk, tablet or PC. On my Apple devices It's nowhere to be seen so, why not have the option to turn it off on M$ products again.
Come on Microsoft, give us back the option to turn it off.
