2. Read and translate the text:

The information your computer uses is stored on disks in files. A file is a collection of related information such as a computer program or the text of a letter. Each file is given a unique name, and each filename is stored in a directory. To find out about the files in a directory, use the MS-DOS command DIR. The instructions used to run a program are stored in program files, and the information you create by using a program is stored in data files.

As you work with a program, operating system processes the information stored in program files and passes it along to your system when it is needed. When you are finished using the program, your data files are stored on a disk.

When referring to a file, you must use a file specification. This consists of a pathname, a filename and an extension (if there is one). As an example, to reference a file on drive B: called FRED.BAS (where the default drive is 'A') the correct file specification would be:

B:\FRED.BAS

File extension can be up to three characters long and are used to identify the contents of a file. MS-DOS automatically defines the meaning of some file extensions. Others can be assigned as you wish. For example,.TXT can be used to indicate a text file.

You assign each file a name so that you can identify its contents. For example, suppose you use a word-processing program to write the notes for a meeting you attended. You might assign the name MINUTES to the data file that contains these notes.

Organizing your files into directories and subdirectories on a disk is like organizing your documents into file folders and then storing them in the drawers of a file cabinet.

Operating system has rules for naming files. It also includes several commands that you can use to work with files.
