This tutorial demonstrates how to upload a .zip file to your D2L course and then unzip the contents so you have access to your files.
When the Upload dialogue box appears, click Upload to browse and select the .zip file you want to upload.
Select the .zip file you just uploaded, click on the down arrow next to the file name, and click Unzip.
Your files will appear in Manage Files and can now be added to modules in the Content area.
Macintosh Note: in some instances, if you create a .zip file from multiple local files on your computer, you may see a folder called _Mac after you Unzip. It is safe to delete that folder and it's contents.
