Subdirectory
A subdirectory is a folder or directory located inside another directory. It is a way to organize files and folders in a hierarchical, tree-like structure to make them easier to locate and manage. For example, a "Documents" folder on a computer might contain subdirectories for different projects, like "Work" and "Personal".
Hierarchical structure: Just like a main directory can contain files, it can also contain other directories, which are then called subdirectories.
Organization: Subdirectories are used to group related files together, reducing clutter in a main folder. For instance, you could have a main "Photos" folder with subdirectories for each year (e.g., "2023", "2024").
Path: To access a file within a subdirectory, you use a path that specifies the main directory and then the subdirectory. For example, Documents/Work/report.docx.
Analogy: The term is similar to how a telephone directory might be organized into sections, with further subdirectories for each section.
