When you upload files to OneDrive, you can update and share them from anywhere. In OneDrive, click Upload browse to the file you want to upload, select Open, and the files upload to OneDrive. Or, you can also drag files from your computer straight to OneDrive.
In the Google Chrome or Microsoft Edge browser, you can upload folders from the Upload menu. With other browsers, create a folder in OneDrive, and then drag or upload the files into them.
