Chapter 13, Problem 1RQE

Program Description Answer

The files are named as “filename” which is used for purpose of identification by user and operating system.

Explanation of Solution

File name:

File name is the name used to identify each file individually to user and operating system.

• The name of the file must be unique and it should differ if it is used in the same directory or folders.
• The file name includes two parts separated by a period (.).
• The first part is most possibly the name of the file and the second part is extension of the file name.
• The extension of the file name may exist with three to five characters in a length.
• The special purpose of using the extension with the file name is that it is used to identify the type of data it contains with it; or sometimes, the extension itself is used to create the file.
  • For example, Microsoft word stores with the extension “.docx”.
