To share files with your students when teaching a class with Zoom, use Zoom’s in-meeting file transfer tool. To learn how to make this feature available by un-hiding it, see this Review of Zoom's Hidden Settings.

Once you've made file transfer available in your Zoom meetings, look for the File button at the bottom of the Zoom chat window.

After you've shared the file, students will see a notice that a file has been made available and will be given the option to download it.
