- anything that adds capabilities to an existing system. For example,optional components of the Macintosh operating system are called extensions.
- the part of a filename following the period, in DOS,Windows, andother operating systems. For example, the filename PROG1.BAS has BAS as its extension.
The purpose of extensions is to indicate the type of file, but it is important to realize that the extension does not actually cause the file to be of a particular type; you can rename any file to have any extension, but when you do, your software may no longer recognize it for what it is.
Some file extensions have standard meanings; see Table 7. See the individual entries in this book for more information on some of the more important types.
A practical problem arises when the same extension is used by different software packages for different purposes. For example, .tex denotes both a TEX word processing document and a Corel Draw texture. When this happens, an extension may end up associated with the wrong piece of software. See associate for information on how to change the software that is associated with a particular extension.
Prior to Windows 95, all extensions could be no more than three characters. Newer file extensions can be longer.
In Windows, it is up to the user whether extensions are displayed or hidden (Figure 99). The choice is under Tools, Folder Options, in any window displaying files or folders. Note that you can be tricked by a filename with two extensions. If someone sends you a file named virus.txt.exe and extensions are hidden, you will see the name as virus.txt and think it is a text file, but if you open it, it will actually execute as a program.
