You will need a file expander (Stuffit, WinZip, etc.) to expand the downloaded .zip file. If not on your machine already, most of these programs can be downloaded from the web, free of charge. Follow the instructions for your software to open the .zip file (usually double clicking on the .zip file will begin the expansion process).
After you expand the .zip file, open the folder "Meeting Abstracts - ECS Toronto, Spring 2013".
Open the "welcome.pdf" file. You will now be on the Toronto Meeting Abstracts landing page. Click on "Table of Contents" to browse through the Toronto Meeting Abstracts.
