How to Format USB Flash Drive to FAT32 [32GB/64GB/128GB]

For external devices, particularly portable USB flash drives and SD memory cards, FAT32 is the standard file system. It is the file system that works best with the majority of popular hardware and operating systems, including Windows and macOS. Portability is a benefit of utilizing the FAT32 file system.

Formatting a 32GB USB flash drive or less to FAT32 is pretty straightforward. However, you can only rely on CMD (often Diskpart and Powershell) and a third-party FAT32 format tool if you wish to format 64GB/128GB/256GB USB to FAT32.

Part 1. Before Formatting USB Drive to FAT32

• Don't forget to back up important files on the USB drive. Either simply copy and paste them into the computer, or use a data backup software.
• FAT32 also has certain drawbacks or, to put it another way, constraints. First and foremost, you must convert FAT32 to NTFS or exFAT if you utilize a single file larger than 4GB. In addition, FAT32 can only be used to format drives between 2GB and 32GB in size according to the manufacturer's standards, which is why native Windows programs have the same restriction. There is no "FAT32" option when changing a USB disk larger than 32GB in Windows Explorer.

Part 2. How To Format USB to FAT32 on Windows 10/11 [32GB or Smaller]

There are typically different ways for users to format USB to FAT32 on Windows 10/11, which has the most excellent compatibility compared to other file systems.

Method 1: Format USB to FAT32 via File Explorer

This approach can only be used to change a USB disk in FAT32 format if it is less than 32GB. Remember that the USB drive's prior data will be deleted during the formatting procedure.

1. Connect the USB drive or the desired external hard drive to the Windows 10 computer.
2. Press the Start button and select This PC to open the File Explorer.

   

3. Right-click on the USB drive that you want to format to FAT32 and select Format in the menu.

   

4. Click the File system drop-down menu and choose FAT32 if it isn't already mentioned. Then, click the Start button.

   

5. A warning reminds you that all data on the USB flash drive will be deleted with the formatting process. Click OK to start changing your USB flash drive to FAT32.

   

6. Once the drive has finished formatting, click OK to complete the procedure.

Note: Please back up your important files in the USB flash drive before proceeding with the Format.

Method 2: Format USB to FAT32 via Disk Management

Your USB drive could not appear in File Explorer if Windows didn't give it a letter for some reason or if its file system was damaged. Fortunately, formatting it from the Disk Management software is simple.

1. Use the shortcut Win+X to open Windows' administrative quick menu.
2. Select "Disk Management." You may also find and launch it from the Start menu by hitting the Win key and entering the utility's name.
3. You will get a list of all storage devices and their partitions while using Disk Management. You should see one or more partitions listed within your disk if it functions correctly. They may each be formatted separately. Alternatively, you can click on each one and choose "Remove Volume" until none are left if you'd rather get rid of them and utilize the whole space on your disk as one continuous block.

   

4. If the space on your USB drive seems empty, right-click on it and choose "New Simple Volume."

   

5. To create a partition, use the "New Simple Volume Wizard" and then format it.

   

6. You may use a lesser volume size if you wish to divide your USB drive into more than one. By doing this, you'll free up space on your disk so that you may subsequently add additional partitions.

   

7. Directly from this wizard, you will be able to give a drive letter to the partition you are creating. Alternatively, you may map it to an empty NTFS folder without providing a drive letter.

   

8. You may select a file system and allocation unit size, input a volume label, and choose whether to use a fast format, much like when formatting from File Explorer.

   

9. The wizard will offer an overview of your options before starting to format. To accept them and format your USB device, click "Finish."

   

Part 3. How to Format USB to FAT32 [64GB/128GB or Larger]

If you want to format 64GB or 128GB USB to FAT32, you can depend on CMD (Usually diskpart and PowerShell) or a Aomei Partition Assistant.

2. Type the command "format /FS: FAT32 #:" in the PowerShell window and hit Enter to execute it. (Instead of using #, use your Drive letter.)

   

3. Your 64 GB USB Drive will begin to format to the FAT32 file system as soon as the command is provided. The procedure could take many hours to finish, but if you want to do it quickly, you can utilize several third-party programs to do it more effectively.

Method 2: Use Command Prompt to Format USB to FAT32

Apart from PowerShell, the built-in Command Prompt in Windows can also be used as a FAT32 format tool.

1. First, connect the USB memory stick to your computer and wait for it to be recognized.
2. Go through Start > Accessories > Command Prompt or Start > Run > type "cmd" > Enter to launch Command Prompt.

   

3. Enter the following command at the Command Prompt if your USB device has been given the letter "F":: format F: /fs:FAT32

   

4. When asked whether you want to continue or stop formatting, hit Y (for Yes) or N (for no).
