NOTE: If you don't understand the concept of File Types, you should read "Explaining File Extensions" by Vic Laurie.
Google converts all file types it searches to either HTML or text (unless, of course, they already are in one of these formats). Google searches a variety of file formats including
File Format Suffix Description Adobe Acrobat PDF A publishing format commonly used for product manuals and documents of all sorts. Adobe PostScript ps A printing format often used for academic papers. Hypertext Markup Language html or htm The primary language for web pages. Lotus 1-2-3 wk1, wk2, wk3, wk4, wk5, wki, wks, or wku A spreadsheet format. Lotus WordPro lwp A word processing format. MacWrite mw A word processing format. Microsoft Excel xls A spreadsheet format.

Clicking on a link to a non-HTML file will launch the associated program for reading the file, provided it's installed on your system.
If you can't view the page in the native format -- for instance, if you don't have Adobe Acrobat on your computer -- or if you want faster access to the file, click on either the "View as HTML" or "View as Text" link. Note: Portions of some files converted to HTML or text may be difficult to read.
You can use the Advanced Search form (see the Sharpening Your Query section in Part I) or the filetype: search operator (see the section Using Search Operators also in Part I) to restrict your results to a particular format.
