If you have a Monthly or Annual Premium subscription to the lynda.com Online Training Library, you have access to the same example files used by the instructors in the courses you watch, allowing you to follow along doing exactly what the instructor is doing with photos, videos, audio files, business documents, and so on. The files are provided in the zip compression format. To download the files associated with the course you're watching, simply click the file link under the Exercise Files tab on a course page. If you're using Windows, you may be asked whether you want save or run the file you're downloading. Click Save File to save the file to your computer. Now, Mac OS X has the built-in ability to unpack zip files, and most Windows PCs have pre-installed software for unpacking zip files as well. If your Windows machine doesn't have unpacking software, we suggest downloading and installing ZipGenius. It's a free utility available at zipgenius.com. Once the exercise files have downloaded to your computer, we recommend placing them on your Desktop, if you haven't done so already, for easy access. If you're a Windows user, your ZipGenius or other unpacking utility application may automatically unpack the files for you. If nothing happens, right-click on the compressed file and choose extract all. Then choose a location to extract the files to--again, we suggest the Desktop-- and then click Extract. Similarly if you're a Mac user, double- click the compressed file to unpack it. Once the exercise files have been expanded, you may delete the zip file or keep it as a clean backup copy of the files you're working on. The instructor of the course you're watching will explain how to use the files you've downloaded.
