: OneDrive for Business operates mostly the same way on a Windows RT–based device as it does on your work computer. The difference is that at this time, you can’t click the Sync button to create an offline cache of files that are stored on OneDrive for Business. You can, however, manually download files to your Windows RT–based device. To download a file, tap or click the button next to the file that you want to download. At the bottom of the file callout, tap or click the button, and then tap or click Download a Copy to download the file to your Downloads folder.
