What does the extention on a computer file name indicate?

Answer 1

The file name EXTENSION (spelling counts in Web searches!) identifies the format of the file and the program that should normally open it. For example, a file with extension .DOC is in Word 97-2004 format and should normally be opened by Microsoft Word. Many programs can open files that are normally opened by another program. For example, most word processors can open .DOC files - a market requirement because there are so many Word users. To do this, it may be necessary to modify system settings (the software may provide users help in doing this) or to launch the application first, then open the file from within it. File name extensions were originally limited to three characters in DOS. Early versions of Windows, which were built on a DOS core, continued this limitation. Many extensions are longer today, such as the .DOCX format for Word documents introduced with Word 2007/2008*. Prior to OS X, the Mac OS did not use file extensions though it allowed them so files could be easily exchanged with DOS/Windows systems. It used internal "type" and "creator" data instead. With the introduction of OS X, the Mac OS uses them in much the same was as do Windows systems: to select the default program to open a file. _____________________________ *Word 2007 is the Windows version; 2008 is the Mac OS version.
