How to Format USB to FAT32 on Windows 11: The Complete Guide

Windows 11 has streamlined many tasks, but formatting a USB drive to the FAT32 file system remains a bit tricky. Why?

So, what do you do if you have a 64GB or 128GB USB drive that needs to work with an old gaming console, a car stereo, or a BIOS flashing tool? You need the right methods.

In this guide, you will learn exactly how to format USB to FAT32 on Windows 11 using four proven methods—from the simple GUI tool for small drives to powerful command-line tricks and third-party software for large drives.
