Files are often compressed, or "zipped up", to make
them easier and quicker to download or upload over the internet, either from a
web site or in e-mail. Many files can be put in a single zip file, and
instead of downloading many files one at a time, you can do it all at once when
they are zipped up. A zip file will have a .zip extension, as
curriculum.zip.

To unzip a file You must have an "unzipping"

WinZip. When WinZip opens, click on the
"I agree" button.
This will bring up the WinZip Wizard with your zipped file
ready for unzipping. It will be unzipped to the "unzipped"
folder on your c:/ drive, but you can select a different folder by clicking
on the "Select different folder" button, and browsing to a folder
of your choice. Click on the "Unzip Now" button at the
bottom and your file will be automatically unzipped.
