[Fix] How to Overcome the FAT32 File Size Limit When Using Large USB Drives – 100% Working!

Ah, the classic FAT32 problem: you’ve got a shiny new USB drive (let’s say it’s a 256GB beauty), and you want to transfer a big file—maybe a high-res video, an ISO, or some game backup. But wait—what’s this? FAT32 just won’t let you transfer a file larger than 4GB. Ugh, it’s like you’ve walked into a fancy restaurant only to realize you forgot your wallet. That nagging 4GB file size limit kicks in, and suddenly you can’t do anything with the drive.

But don’t worry, my friend! We’re about to 100% fix this issue, no magic tricks required. You won’t need to toss your USB drive out the window (although it might feel tempting). By the end of this blog, you’ll learn how to overcome the FAT32 file size limit without breaking a sweat.

Why Is FAT32 Still So Popular?

First off, let’s take a quick look at why FAT32 is still around. Despite its age (it was first introduced in the mid-1990s), FAT32 is still one of the most widely supported file systems. It works with almost every operating system (Windows, macOS, Linux), gaming consoles (hello, PS4 and Xbox), and even older devices like cameras and printers.

But the downside? FAT32’s file size limit of 4GB per file. While that’s fine for smaller files (pictures, documents, etc.), it can be a major headache when dealing with larger media files, software backups, or game files.

So how do we fix it? Let’s dive right into real solutions that actually work.

[Fix #1] The Quick and Easy Way: Reformat the Drive to exFAT

Okay, let’s not waste time. The quickest and most straightforward way to fix the FAT32 file size limit is by reformatting your drive to exFAT. exFAT, unlike FAT32, supports much larger file sizes (theoretically up to 16 exabytes!). It’s pretty much a miracle for anyone who wants to work with large files.

Here’s how to do it:

1. Back up your data: Reformatting erases all data on the drive, so make sure to back everything up to another drive or cloud storage before proceeding.
   
2. Format the drive (Windows):
   • Open File Explorer.
   • Right-click on your USB drive under This PC and select Format.
   • Under File System, choose exFAT from the drop-down menu.
   • Set Allocation unit size to Default.
   • Check the box that says Quick Format and hit Start.
   • Wait for the process to finish, and boom—your drive is now exFAT and can handle files larger than 4GB!
     
3. Format the drive (macOS):
   • Open Disk Utility.
   • Select your USB drive from the sidebar.
   • Click Erase and choose exFAT as the format.
   • Hit Erase again and wait for the process to complete.

With this simple step, you’ve officially defeated the FAT32 file size limit. Go ahead, transfer that 10GB movie file without any trouble. You’re free to live your best life!

[Fix #2] The Techie Way: Use the Command Line to Format with exFAT (Windows)

For the more technically inclined, we can go a bit deeper with the Command Prompt method to format your drive as exFAT.

Here’s how to do it:

1. Open Command Prompt as Admin:
   • Type cmd in the Start menu search bar.
   • Right-click on Command Prompt and select Run as administrator.
     
2. Run the Format Command:
   • Type the following command to format your USB drive: luaCopyformat X: /FS:exFAT Replace X with the drive letter of your USB drive (e.g., C: or D:).
     
3. Follow the prompts:
   • You’ll be asked to confirm the format and whether you want to perform a quick format. Once confirmed, the drive will be formatted to exFAT.

This method can be helpful if you prefer working in the Command Prompt or need to format multiple drives quickly. It’s a neat and efficient way to handle large files on your USB storage!

[Fix #3] The Hybrid Approach: Split Large Files for FAT32 Compatibility

Maybe you’re dealing with a situation where you can’t change the file system (hello, console limitations). Don’t panic just yet! If you absolutely need to keep your drive as FAT32, you can split large files into smaller chunks that fit within the 4GB limit.

Here’s how to do it:

1. Use a file-splitting tool like 7-Zip or WinRAR:
   • For 7-Zip, right-click your large file and select 7-Zip > Add to archive.
   • In the Archive format dropdown, select ZIP.
   • Under Split to volumes, bytes, set the size to something below 4GB (e.g., 3GB).
   • Hit OK, and 7-Zip will split your file into manageable chunks.
     
2. Transfer the smaller files to your FAT32-formatted USB drive.
   
3. Reassemble the files:
   • When you need to use the file again, open the first part with 7-Zip or WinRAR, and extract all parts to restore the original file.

This is a bit of a hassle, but it’s a viable workaround when you can’t reformat your drive. However, for long-term use, exFAT is still the superior option.

Why You Should Avoid FAT32 in 2025 (Unless You Really Have To)

At this point, you might be wondering, “Is FAT32 really still necessary?” In 2025, with flash storage, external drives, and USB drives getting larger, there’s absolutely no reason to stick with FAT32 if you can help it. You’ll run into constant headaches—whether it’s the file size limit or the occasional incompatibility with larger partitions.

• exFAT is better suited for today’s storage needs.
• NTFS is perfect if you need advanced features like file permissions and security.

FAT32 is really a relic of the past, and unless you’re dealing with older hardware or gaming consoles that demand FAT32, it’s time to move on. Save yourself the headache and switch to something more modern.
