This appendix lists many of the most common filename extensions that you'll find on your system, that you might download, or have sent to you over the Internet.
Extensions were universally used on DOS and Windows 3.1 files, but
Microsoft has gone to some difficulty to hide them in Windows XP.
This is unfortunate, since they play a major role in the way Windows
decides what application will be used to open a file, as well as
which files will be visible when opening files in a given
application. While direct associations are made between some files
without extensions and the applications needed to open them, in most
cases, the association is between an extension and a Registry setting
that tells the system what application to use. To enable the display
of filename extensions, go to Control Panel
If you double-click on an unknown file type, the Open With dialog box (see "Folder Options" in Chapter 4) appears, allowing you to make a new association. To subsequently change an association once it has been made, right-click on the file and select Open With, or select Properties and then click Change.
We've tried to list the most common system extensions in Table 1, but there are literally thousands of file formats used by third party applications. And you might be thrown off by an improperly named file, or an application using a standard filename extension for a nonstandard purpose.
Many of these file types can be opened only if you have the appropriate application. However, especially with the growth of the Web, there are often viewers available that allow you to at least view the contents of the file, even if you can't change them. Your web browser and the Windows Picture and Fax Viewer are capable of reading several formats. Paint Shop Pro (http://www.jasc.com) can read and convert nearly any image (graphics) format. And any modern word processor (WordPerfect, Word, etc.) will be able to read just about any text-based document and convert it to a more usable format. If all else fails, you can open just about any file in Notepad; while nontext files will look mostly like jibberish, you may get clues in some of the excerpts of readable text you'll see.
If you still can't find a file's type from it's extension, there are several more good sources:
Microsoft has put together a simple "extension finder" web site, intended for use with the "Use the Web service to find the appropriate program" feature that appears when you try to open a file with an extension that Windows doesn't recognize. The address for this site is:
where {your extension} is the filename extension (without the dot) that you wish to learn more about. For example, to find out about the .sit extension, you'd go to:
Use an ordinary search engine such as Google (http://www.google.com) to search for references to the filename extension. For example, to find out about the .hqx extension, try searching for "hqx file" (with the quotes).
For more details on dealing with downloads and file formats found on the Net, see
Internet in a Nutshell , by Valerie Quercia (O'Reilly). For details on the internals of many graphics file formats, see
The Encyclopedia of Graphics File Formats by James Murray and Bill van Ryper (O'Reilly).
