In the context of file systems, what is the primary purpose of a file system 'metadata'?

Correct option is D

The correct answer is (D) To record information about the files and directories, such as their names, sizes, timestamps and permissions

Explanation:

• Metadata in a file system is crucial as it stores key information about the files and directories, but not the actual content.
• This includes attributes like the name, size, timestamp (created, modified), permissions, location on the disk, and other attributes necessary for managing files effectively.
• It helps the operating system in locating files, managing access, and ensuring proper organization of the file system.

Information Booster:

• Metadata does not store the actual file data, it simply contains the information about the file's attributes.
• In some file systems, metadata also includes details such as the file type, ownership, and access control settings.
• Metadata is essential for the efficient functioning of file systems and helps in faster file retrieval and management.

Additional Knowledge:

• Option A: Optimizing physical storage is the job of the file system itself, but metadata specifically deals with file attributes, not the storage structure.
• Option B: The graphical representation (e.g., icons, file explorers) is managed by the operating system or graphical user interface (GUI), not the metadata.
• Option C: The actual file content is stored separately, while metadata only stores the file's information like name, size, and permissions.
