An operating system consists of directories that manage files for software applications. Subdirectories are directories within other directories, except for the root directory. A meaningful directory tree is important for finding information. Too many subdirectories can be difficult to manage. Hidden files and directories protect information from users and hackers.
A typical computer operating system consists of folders, which contain data related to software applications maintained on the computer. These folders, called directories, are the directories for software applications and the operating system to manage files specific to your computer. It is common to find that a directory contains a subdirectory within it, which is simply another directory within an operating system’s directory tree.
A subdirectory is just a directory within another directory or a folder within a folder. All directories can become a subdirectory except the root directory, which is typically referred to as the root directory or parent directory. The root directory is the primary directory located at the top of the directory tree.
A directory is a folder that contains information files relevant to specific tasks. Many of these folders can be changed both in name and in content. As with any directory, they can also be moved or copied to another directory within the operating system.
Within most operating systems, thousands of files are created to manage normal computer operations. These file systems are quite complex and require a significant directory tree structure for proper management. It is typical to find that a specific directory may contain subdirectories protected from user modification. This protection is necessary to ensure operational stability within the computer operating system.
It is important to create a meaningful directory tree when using any operating system, as this ensures that critical information will be correctly identified in the future. The directory tree can be compared to the index catalog typically found in most libraries. This directory is the main method for finding information on a specific topic, and the sub-directory is a further delimitation of information on a specific topic.
Many graphical user interfaces (GUIs) and operating systems can only maintain a limited number of subdirectories within a directory. While this differs based on the software application, it’s best to keep a subdirectory restricted to a manageable level of separation. Too many levels of subdirectories become difficult to maintain and should be avoided.
An interesting feature for directories in most operating systems is the ability to hide files. Hidden files or hidden subdirectories are a method of protecting information from computer users or hackers. A hidden directory is a marker that is placed on a directory to identify the folder as hidden, which will cause a search to ignore the protected folder or subdirectory.
