Since each computer platform has different conventions for working with files, you should keep the following rules in mind when creating pages. Some of these tips can also assist you when organizing and working with the files in your web space. This extension tells the computer what type of information is contained in that file, so that the computer knows what application to use to edit the file or how to serve the file to a web browser. The above rules take into account the way that different computer platforms handle filenames. For example, special characters are often reserved and cannot be used in a filename on some computers, but may be allowed on others.
Web pages are, invariably, always under construction.
What may begin as a simple web page can expand to a number of sections and pages in a short period of time. You can make your work easier by using filenames to organize the files that comprise your web space. The sample file list below shows a web space that includes multiple sections, each with their own graphics.
