Method 2: Format USB Flash Drive to FAT16 Using CMD
Applicable: USB drive size > 4GB
Fortunately, Diskpart has been accessible on Windows since Windows NT and is still an actively supported component, so we can use it as a FAT16 formatter. But, we must resize the USB drive for it to be formatted using the FAT16 file system since the current flash drive far surpasses its file system limitations.
Step 1. Enter the “Diskpart” at the command prompt, which is in the folder x:\Windows\System32.
Step 2. To find the USB flash drive, type “list disk.” For example, it is disk 6 in this instance.
Step 3. Simply type “select disk 6” to choose the USB drive. (Where the number found in step 2 is 6) list-disk
select the usb you want to format to fat16
Step 4. Delete all partitions if the USB drive has already been formatted with a contemporary file system by entering “list part.” Type “select part 1” since this disk has only one partition. Then, enter “delete part.”

Step 5. Type “create part primary size=4000” to create a partition with a size of 4 GB.

Step 6. Enter exit.
Step 7. By entering “format X: /FS:FAT/Q” at your command prompt, where X: is the drive letter of your USB flash drive, you may format the disk to FAT16.
