Which file system would you expect on very small removable media such as old floppy disks?

• A. FAT16
• B. FAT12
• C. NTFS
• D. FAT32

Answer: (B)

On very small removable media, you want a simple, compact way to manage space. FAT12 achieves this because it uses 12-bit entries in the File Allocation Table, which keeps the table small and supports only a limited number of clusters—perfect for disks like the 1.44 MB floppy. That low overhead makes FAT12 the natural choice for such tiny media and ensures broad historical compatibility with older hardware and software. FAT16 and FAT32 require larger FAT structures and more clusters, which adds overhead and isn’t needed for tiny disks. NTFS is a modern, feature-rich filesystem with journaling and permissions, designed for larger, contemporary storage, and it isn’t suitable for the constraints of floppy disks. So the best pick for very small removable media is FAT12.
