If you need to create a new file from scratch, you can do it right from within OneDrive for Business.
- Click the New button.
- Select a file type.
A new file appears and is ready to populate.
- Add content to the new file.
- Click the Name in the title bar.
- Type a file name.
The changes you make in any of the online Office apps are automatically saved.
- Close the file.
The new file is added to the library, and you know it's new because of the little green icon next to the name.
