An 'upload' or 'download', to me, would imply that the files are being transferred into 'online' storage.
This would be done over your internet(broadband) connection. Dropbox, SkyDrive, iCloud, The Cloud, are examples of 'Online Storage'.
Are you trying to transfer the files using a website, or via direct transfer from one drive to another using 'My Computer' or 'Windows Explorer' ?
This is where it might get tricky and confusing. I can access my 'OneDrive' online account through 'My Computer'
