Performing Basic File Operations
When you open a file, the operating system selects an appropriate program
to display the contents of the file based on the file format. For example,
when you open a Word document, the operating system opens a word processor,
such as Word 2007, to display the contents of the document.
In this simulated lab, you will create and save a file, browse the file,
delete the file, and restore the file.
Click to launch the lab. Follow the steps to complete the lab.
Every file has an associated format that defines the way data is stored in
the file. 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 (.docx)
Images (.gif and .jpg)
Executable programs (.exe)
Multimedia files (.wma and others)
