Performing Basic File Operations

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 (.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. For example, when you open a Word document, the operating system opens a word processor, such as Word, to display the contents of the document.

To understand this concept of performing basic file operations, consider a scenario. You want to create a document by using WordPad. You are new to the concept of files and want to know how to create and save the file in a specific location. You also want to know how to open or delete an existing file.

In this exercise, you will explore how to perform basic file operations.
