What does "file system" mean?

Before we dive into exFAT, it's important to understand what a file system is. A file system is a method for managing how and where data is stored on a storage disk. It performs the translation from logical file operations to the physical storage of information. In other words, it governs how data is stored and retrieved.

To understand file systems, you need to understand their architecture. A file system has two to three layers. The logical file system provides the application programming interface for file operations. When a request is made, it passes the operation down to the next layer. Physical operations on storage devices require a third layer.

What is the exFAT file system?

When you format a hard drive, USB flash drive, or SD card, you're usually given the option to choose between NTFS, FAT32, and exFAT. What is exFAT, and when should you use it? Read on to learn about this cross-compatible file system that's supported by many different operating systems.

Windows supports three different file systems. NTFS was introduced with Windows NT but became widely used after Windows XP. It is the most advanced file system. FAT32 is a file system that was first introduced with Windows 95. It's an older file system that isn't as efficient as NTFS. exFAT (Extended File Allocation Table) has broad compatibility and fewer restrictions on file and partition size. It was introduced with the Windows XP and Vista operating systems. It's a modern alternative to FAT32.

Compatibility: Works with all versions of Windows and Mac. If you've got extra software on your computer, it can work with Linux, too.

Limitation: The maximum cluster size for exFAT is 32 MiB.

### Where is exFAT used?

exFAT is widely used by many manufacturers. Your USB flash drives, SSDs, and HDDs might be formatted with exFAT. While there are no technical limitations regarding file size, exFAT performs best when you have less storage space on your device. This is why most people still use this file system.

• exFAT is useful when working between different operating systems.
• exFAT addresses the issue of storing large files across different platforms.
• exFAT performs better than NTFS on cameras, car stereos, and media players.
