Smaller cluster sizes make for less waste of disk space. The smaller the cluster size is, the bigger the file allocation table (FAT) will be. The bigger the FAT is, the slower the operating system works with the disk.

Why Do We Format USB to FAT32?

Related topic: Should you format USB to FAT32 or NTFS?

What's FAT32? FAT32 is regarded as the default file system for external drives, especially removable USB flash drives and SD memory cards. It's the most compatible file system for major devices and operating systems like Windows and macOS. So, the advantage of using FAT32 is portability.

However, FAT32 has some disadvantages and, let's say, limitations as well. First and foremost, if you use a single file over 4GB in size, you'll need to convert FAT32 to NTFS or exFAT. What's more, due to the manufacturers' specifications, FAT32 can only be used to format drives between 2GB and 32GB, and that's why native tools on Windows have that limit, too. When you try to format a USB drive over 32GB in Windows Explorer, there is no "FAT32" option.

Do You Know How to Format USB to FAT32 Now?

Regarding the topic "how to format USB to FAT32", we analyzed the FAT32's advantages and disadvantages and clearly know that the regular Windows File Explorer and Windows Disk Management can only deal with USB drives under 32GB. If you're trying to format a large USB drive that is 64GB or 128GB, you'll need to download the third-party formatting software - EaseUS Partition Master Free or challenge yourself to learn the Diskpart or PowerShell commands.

All in all, no matter how large your USB flash drive is, EaseUS FAT32 format software is the optimal choice to format your USB drive to FAT32. It doesn't require the USB storage size, and most of all, it's user-friendly, and everyone can benefit from it.

  • It won't hot image your drives or align them, but since it's coupled with a partition manager, it allows you do perform many tasks at once, instead of just cloning drives. You can move partitions around, resize them, defragment, and more, along with the other tools you'd expect from a cloning tool.
