A file system hierarchy is the structured organization of files and directories within a file system. It defines how files are stored, accessed, and managed on a storage device. In Unix-like operating systems, the hierarchy starts from the root directory ('/') and branches out into various subdirectories.
Key features of a file system hierarchy include:
- Root Directory: The top-level directory from which all other directories branch out.
- Subdirectories: Directories that exist within other directories, allowing for organized storage of files.
- File Paths: The way to access files and directories, typically represented as a sequence of directory names separated by slashes (e.g.,
/home/user/documents). - Standard Directories: Common directories like
/bin,/etc,/home, and/usr, each serving specific purposes (e.g., system binaries, configuration files, user home directories).
This hierarchical structure helps users and applications navigate the file system efficiently.
