But don’t worry, in this article, we’ll walk you through the steps to successfully format your 128gb USB to FAT32 on Windows 10. So let’s get started!

Why Format a 128gb USB to FAT32?

Before we dive into the steps, let’s first understand why you would want to format a 128gb USB to FAT32 in the first place.

FAT32 is a file system that is compatible with both Windows and Mac operating systems. This means that if you want to use your USB on both a Windows and Mac computer, formatting it to FAT32 is the best option.

Additionally, FAT32 has a maximum file size limit of 4GB, which may be useful if you want to use your USB to transfer files between devices that have this limitation.

Limitations of Formatting 128gb USB to FAT32 on Windows 10

While FAT32 has its advantages, there are limitations when it comes to formatting a 128gb USB on Windows 10. The main limitation is that Windows 10 only allows you to format a USB to FAT32 if it is 32GB or smaller.

This means that if you have a 128gb USB, you won’t be able to format it to FAT32 using the traditional methods. But don’t worry, we have a solution for you.
