Many of the resources or samples David C Cook delivers to you are collections (bundles) of multiple files and media. These files are compressed (zipped) together in one large file. In order to use the individual files on your computer, you will click or double-click the filename to open and reveal the files contained inside.
In very few cases, a computer may not have the correct program registered to open the downloaded .ZIP file.
