Directory

Definition

A directory is a structure within a file system used to store and organize files on a disk. Directories can contain files, as well as other directories, which are known as subdirectories. The term directory is synonymous with folder in modern operating systems like Microsoft Windows and macOS.

Examples

Main Directory: The top level of a file system, often referred to as the root directory, is usually represented by a single ‘/’ in Unix-based systems or ‘C:' in Windows systems.
Project Folder: A directory named Project1 could contain multiple files such as project1.docx, report1.xlsx, and another subdirectory named Images.

Q2: What is a root directory?

A2: The root directory is the top-most directory in a file hierarchy. It serves as the parent for all other files and directories.

Q3: Can directories contain other directories?

A3: Yes, directories can contain other directories, known as subdirectories, allowing hierarchical organization of files.

Q4: How are directories represented in Unix-based systems?

Root Directory

The root directory is the primary, top-level directory in any file system from which all other directories branch out.

Subdirectory
