This includes floppy disks, USB flash drives, and most digital cameras. “FastFAT.sys” is in “C:\Windows\System32\drivers” and the system loads it using an API called IFS (Installable File System). By moving FAT driver logic outside the kernel into 32-bit PE executables, Microsoft achieved massive optimization, thus the “FastFAT” name.
