This step-by-step guide shows How to Format USB to FAT32 on any Windows PC or Mac computer.
The process of formatting a USB drive to the FAT32 format is simple and takes less than five minutes.
We hear of many individuals struggling to connect their USB drives to Amazon Firesticks and other Android-powered devices.
The main reason for this is because they haven’t formatted their devices as FAT32.
FAT32 stands for “File Allocation Table” with 32 referring to the 32-bit version of the FAT file system.
The FAT32 format is one of the most popular formats used on USB drives, external hard drives, and memory cards to ensure compatibility between all platforms.
IMPORTANT NOTE: When you format a USB drive you are erasing everything. If you have important files on your USB drive make sure you back them up prior to formatting as FAT32.
The Windows PC disk utility only allows for formatting as FAT32 if a USB drive is 32GB or smaller. This tutorial will show you how to get around that constraint.
We also show you how to use Disk Utility in Mac computers to format any size of the USB drive as FAT32.
TROYPOINT TIP: We suggest watching the video below for important details about the FAT32 format.
In the tutorials below, we are using a SanDisk 3.0 USB Drive on a Windows 10 PC.

Follow the step-by-step screenshot guide below for formatting your USB drive to FAT32.
The first example is for those using a 32GB USB drive and following that you will find instructions for a 256GB USB drive.
32GB USB Drive
1. Insert your USB drive into your Windows PC and Windows File Explorer should automatically open.
2. Locate and click your USB drive. In my case, the USB drive is labeled “SANDISK32.”
3. If your USB drive is 32GB or less, you can easily format your drive through Windows Explorer.
To do this simply right-click your drive and then left-click Format.
4. Change your File system from “exFAT” to “FAT32” from the dropdown menu. Then click Start.
5. You will be prompted with a warning message. As mentioned previously, changing your USB drive to the FAT32 format will erase everything. Click OK.
6. The format has been completed. This disk is now in the FAT32 file system. Click OK.

14. That’s it! Your 256GB USB drive is now formatted as FAT32. Exit out of the Rufus program.
