I have been trying to setup onedrive to sync to a flashdrive on my windows 8.1 tablet. Can't figure out how to do it and read numerous articles. Then tried to just copy my onedrive folder from another computer to the flashdrive but I get an unexpected error 0x80070780. Also get an access denied error when trying robocopy. Any ideas how to copy or sync my onedrive folder to a flash drive? Copy would be fine. Syncing on my limited space 8.1 tablet would be great.
