What if my ZIP file or PDF file is empty?
If you’re using a Windows device, you may see an error message that states the contents of the ZIP file are empty, specifically when opening PDF files within it. This tends to happen when the default program for downloading and extracting ZIP files on your device has changed.
To avoid any issues with downloading the ZIP file to your device, right click on the LessonMakers download link and choose ‘Save as…’ to save the ZIP file to your desktop instead of clicking the ‘Download’ button.
Please be sure that your default ZIP file extraction software is correct. For example, you will not want to try extracting a ZIP file with a web browser such as Microsoft Edge as it won’t work properly. You can find more information on how to change your default software for ZIP files here:
After extracting the files within the ZIP, we recommend opening PDF files with Adobe Reader, which can be downloaded for free here:
