What is the difference between fat32 and fat64?

FAT32 and exFAT (often mistakenly referred to as FAT64) are both file systems used for storage devices, but they have key differences. FAT32 supports file sizes up to 4GB and partitions up to 8TB, making it suitable for smaller drives and compatibility with a wide range of devices. In contrast, exFAT, which is designed for flash drives and external storage, allows for much larger file sizes (up to 16EB) and partitions, providing better performance for large files while maintaining compatibility across various operating systems.
