Fat32 is a helpful disk format that organizes stored files on a disk drive. And there is a maximum file size in FAT32. At the start of creating a drive, it will be marked up into chunks called sectors, to which you can find pieces of information on your computer. From a wide range of disk formats, FAT32 is only the format that is supported on Mac and Windows. Unfortunately, you may receive an error because of the large size. To avoid this, let’s discuss the mac file size for FAT32. And this post will teach you how to transfer a file whose size is beyond the maximum.

Part 1: What is the File Size Limit for FAT32

FAT32 is a unique file system that you have just encountered yet. From its definition and usage, the disk format can be tricky, and difficult to retrieve data from your devices. Still, you must also know the max FAT32 size to prevent wasting time re-uploading or restoring important data.

1. The size for FAT32 Max Files

The disk format’s maximum file size for a singular file is 4GB. Although this is huge enough to store information from one file, there is a chance that you may run into some trouble, like the data being too large for the destination system.

2. Why FAT32 Has Limitation for File Size

FAT32 has a built-in limitation for file sizes. It may sound silly, but the developers back in the day did not anticipate the larger files today. Additionally, the designers thought that the common large files became a big chance FAT32 would be replaced with newer ones. That is why even if you copy files amounting to 2TB, an individual file can only be at 4GB maximum.

But are there solutions for max FAT32 size? Definitely, yes. There are newer file systems that will not limit file size to 4GB. However, here are more effective solutions to store data without receiving an error.

1. Change the File System to NTFS or exFAT from the USB Driver

As mentioned, modern file systems are better alternatives for max FAT32 size. NFTS and exFAT are the most recent systems to use the drive on your PC. NTFS is suitable for flash memory and is supported by all Windows versions and the latest Mac versions. While exFAT provides 16TB as the maximum file size and is supported by many third-party manufacturers. Changing the file system on your device is relatively easy, and here’s how to do it on Windows 11/10/8/7 and Mac:

For Windows users:

Step 1.Press "Windows + R" keys on your keyboard and type diskmgmt.msc to launch Disk Management. From another window, choose the desired partition and right-click on it. Select the Format option from the drop-down list.

Step 2.Choose the NTFS file system from the submenu, then set the allocated unit size by default. Tick the "Perform" checkbox for a quick format, and then click "OK" to apply the changes. The file system will then change from FAT32 to NTFS.

Step 2.Click the "Erase" button and then proceed to select exFAT from the format list. Input the desired "Volume Label" and click the "Erase" button again.
