What do we call a collection of files and directories in Linux?

The term used to refer to a collection of files and directories in Linux is the file system. A file system organizes how data is stored and retrieved on a storage device, defining the structure and rules for file management, such as how files are named, how directories are organized, and how data is accessed.

In Linux, the file system provides a hierarchical structure where files and directories are arranged in a tree-like format, starting from the root directory. This system allows for efficient organization and management of files, making it essential for the operating system to function effectively.

While "folder," "directory structure," and "repository" are related concepts, they do not accurately define the entire collection of files and directories. "Folder" is often used interchangeably with "directory" in graphical user interfaces and can be considered a specific type of directory. "Directory structure" describes the layout and organization of directories within a file system but does not encompass the entire set of files contained within. A "repository" typically refers to a storage space for software packages or source code rather than the broader organization of files and directories on a system.
