The file format is identified by a period (also
called a dot) appended to a file name, followed
by three or four letters.
The following are some of the more common file
formats:
 Word documents (.doc)
 Images (.gif and .jpg)
 Executable programs (.exe)
 Multimedia files (.wma and others)

When you open a file, the operating system
selects an appropriate program to display the
contents of the file based on the file format.

the operating system opens a word processor,
such as Word, to display the content of the
document.
