Part 1: "FAT32" vs. "exFAT": What's the Difference and Which One Is Better?

"FAT32" (File Allocation Table) is the most popular file system as it is the oldest and is used by almost every Operating system. But, "exFAT" is the latest file system which is widely used in formatting external and USB drives. Let us understand which one is better by comparing the following:

Based on the above table, it is proven that the "exFAT" file system is far better than the "FAT32" file system when you have files with large sizes and need effective and efficient formatting.

Why Move to exFAT? The 4GB Limitation?

The most common reason for this conversion is the 4GB file size limit inherent in FAT32. If you try to transfer a high-definition movie, a large 4K video project, or a massive database file larger than 4GB to a FAT32 drive, Windows will return an error stating the "File is too large for the destination file system." exFAT removes this barrier entirely, supporting individual files up to 16 Exabytes (EB).
