Explain what you must keep in mind when you choose filenames.

What will be an ideal response?

When you name a file, you should use a descriptive name that reflects the file's contents. For example, if the page is about a company's products, you could name it "products." You also must follow some general rules for naming Web pages. For example, the home page should be named "index.html" or "default.html." You can also use the file extension "htm" instead of "html." Do not use spaces, special characters, regular or back slashes, or punctuation in Web page filenames or in the names of any images that will be inserted in your website. Another rule is not to use a number for the first character of a filename. To ensure that everything loads properly on all platforms, including UNIX, assume that filenames are case sensitive and use lowercase characters. A good practice is to limit file names to eight characters.
