“mkfs.fat” is a command-line utility that creates a Microsoft File Allocation Table (FAT) filesystem on a partition or disk. This filesystem is commonly used on removable drives and other storage devices that need to be compatible with different operating systems, including Microsoft Windows, macOS, and Linux. The “mkfs.fat” command initializes the partition, creates the necessary file and directory structures, and writes the boot sector and other required information to the partition. After the process is complete, the partition is ready to be used to store and access files.
