You will find a variety of different types of files on Wiley's server. Each different file type is designed to be used by one or more specific software programs. Here's a brief guide to the file types available for download at Wiley:

PDF files (.pdf):
PDF (Portable Document Format) files are designed to be used with Adobe Acrobat Reader, Acrobat Capture, Adobe Distiller, Adobe Exchange, and the Adobe Acrobat Amber Plug-in for Netscape Navigator. With PDF files, we can present you with sample material that includes all the photos, art, and design elements you'll find in the finished product. PDF also allows us to offer key ancillary material (such as Instructor's Manuals, Solutions Keys, etc.) in an easy to download, easy to read format. All you need is the Adobe Acrobat Reader to view and print the material. Many browsers also offer pdf plug-ins that permit PDF files to be viewed within the browser itself.

ZIP files (.zip):
ZIP is a file extension (usually DOS or Windows) for a file compressed using a ZIP compression utility. ZIP takes multiple files and makes one single compressed file which is easy to download. A ZIP file might contain any type of files for any program. For example, we occasionally offer software programs designed to accompany a specific text. These programs are often delivered over the internet in a zipped file. Once you download a zipped file to your computer, you need to DE-compress the files with a program like WinZip. Macintosh users can upzip files using Stuffit Expander. You can also configure your browser to automatically deal with ZIP files that it encounters. Please see the users guide or help section of your current web browser for instructions on how to configure your browser to deal with ZIP files.

PowerPoint files (.ppt):
Microsoft PowerPoint allows users to organize, illustrate, and deliver ideas with professional impact. With PowerPoint, users can create slide shows that are graphically rich and attractive. Many Wiley textbooks are accompanied by PowerPoint slides designed to be used in the classroom. If you have the PowerPoint software you're all set. Otherwise, you can download a free viewer at Microsoft.

Sound files (.au, .aiff):
You may run across a few sound files here-- if you do, just click on the link and the file will be downloaded to your computer. Your helper applications or browser plugins need to be configured to know what to do with this type of file. Please see the users guide or help section of your current web browser for instructions on how to configure your browser to deal with sound files.

Shockwave files (.dcr):
A Web browser plugin which provides for Macromedia Director movies to be viewed on World Wide Web pages. Shockwave is an outstanding way to offer software demos over the web. To view Shockwave files, you need the Shockwave plug-in for your browser.
