FAT32 vs Exfat: What Is the Difference Between the Two File Systems

FAT32 is one of the oldest file systems used on a Windows system. The file system was introduced during Windows 95 and replaced the older FAT16 system used in MS-DOS and Windows 3 systems. FAT32 has ideally become the de facto standard for most computer systems. Most of the flash drives available today come with the FAT32 file system and thus offer a high degree of compatibility across Mac and Windows rather effectively.

When using a FAT32 file system, the prime issue is that it is limited to 4GB in size. The files system cannot work with any higher file size than that. That should ideally make it a good choice for flash drives and USB drives, but never on an internal drive.

The exFAT or Extended FAT file systems was introduced in 2006 with Windows XP and were planned as a great means of overcoming the limitations on the FAT32 system. The file system is optimized for flash drives and works great for both internal and flash drives. The key differences between ExFAT and FAT32 can be summarised as follows.

Comparison FAT32 exFAT
Introduced In With Windows 95 In 2006 with Windows XP 
Compatibility with Flash Drives Easy to use quicker  Best meant for flash drive
Windows Compatibility  Works with all Windows versions Works with all Mac versions
Special Configuration  Not needed Mac device needs additional software
Size Limit Max file size limited to 4GB No size limit 

Obviously enough, the exFAT file system should be the right choice when you compare it to the FAT32 for a wider range of reasons that have already been outlined above.  

Final Words

Well, formatting a USB drive so that it is compatible with both Mac and Windows can be quite simple if you are aware of which file systems to choose from. While there are several methods available for formatting a USB drive for PC and Mac, using a third-party utility - EaseUS Partition Master can prove to be one of the excellent options.
