Can’t I format 128GB USB flash drive stick to FAT32?

“I intend to format my 128GB SanDisk USB flash drive stick into FAT32, thus I can use it in different electronic devices. But there is no FAT32 option in Format window. I have ever formatted a 16GB SD card into FAT32 file system successfully within File Explorer. What happens? How can I change my USB flash drive to FAT32 file system in success? Thanks!”

A USB format tool is helpful!

FAT32 (File Allocation Table 32), used as an extension of FAT16, has great compatibility. It can be supported by PSP, XBOX360 and etc. Usually, you can format a drive into FAT32 in Windows smoothly. However, Windows supports you to format partition not larger than 32GB to FAT32: within File Explorer or Disk Management, FAT32 option doesn’t exist; within Diskpart utility, an error message- the volume is too big for FAT32.
