What is a file system, and which three are common on Windows, Linux, and macOS?

• A. A file system organizes and stores files; examples include NTFS (Windows), ext4 (Linux), APFS (macOS).
• B. A file system is a type of internet protocol.
• C. A file system is a hardware component.
• D. A file system is a browser setting.

Answer: (A)

A file system is the way an operating system organizes and manages files on a storage device. It defines how files are named, stored in folders, and tracked with metadata such as permissions and timestamps, as well as how space is allocated and reused. The three common ones are NTFS for Windows, ext4 for Linux, and APFS for macOS. NTFS supports security permissions and reliability features, ext4 is a robust, widely used Linux default with journaling, and APFS is Apple's modern system optimized for SSDs with features like space efficiency and snapshots. There are other formats as well, but these are the typical ones you’ll encounter across the main desktop platforms.
