USING FILES AND DIRECTORIES

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. 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).

File extension can be up to three characters long and are used to identify the contents of a file. Operating system 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.

Organizing Files into Directories

A disk can hold several hundred or even thousands of files, depending on its size. The more files you have, the more difficult it is to keep track of them. To help you keep track of your files, you can use operating system commands to group your files into directories. Operating system lets you organize the files on your disk into directories. Directories are a way of dividing your files into convenient groups. Just as file folders in a file cabinet contain groups of related documents, directories contain groups of related files, such as the minutes and expense reports you create by using a word-processing program. You assign each directory a unique name so that you can identify it.

A directory may contain any number of files, but it is often more convenient to separate the files into subdirectories. When your directories become too large, you can use OS to create additional directories to further organize your files. A directory within another directory is called a subdirectory. This method of organizing the disk is rather like a tree where the files are the leaves of the tree and the directories are the branches. (The first directory is usually called the "ROOT").

You can have more than one file (leaf) with the same name if the files are in different directories.

The organization of directories, subdirectories, and files is called the directory tree. When you format a disk, OS creates one large directory, called the root directory, on the disk. All other directories you create branch out from the root directory.

You must tell the computer which directory it must use as its current working directory – that is, the directory you wish to work in.
