You just got a new drive, or perhaps it\u2019s one you\u2019ve owned for some time. It could be an external or internal HDD or SSD, a USB flash drive, or a memory card. In the process of formatting it, you\u2019ll notice that there are three Microsoft Windows file system options to choose from\u2014FAT32, exFAT, and NTFS.<\/p>\n

What if I told you that each option has distinctive characteristics that would later prove pivotal to what you can do with your drive, the files you can store on it, as well as how those files will be handled? No pressure, right?<\/p>\n

This guide will tell you what you need to know about these three separate file systems so that you can make the right choice and avoid had-I-knowns down the road. Don\u2019t worry. We\u2019ll keep it simple.<\/p>\n

What Is a File System?<\/h2>\n

Before you can begin to send files to your new drive, you have to format it with a file system. A file system provides a method for storing and retrieving files. Without it, everything will be thrown in randomly to make one big data lump with no way to locate items or even tell them apart.<\/p>\n

Picture a library without shelves and piles of books scattered all over.<\/p>\n

File systems divide the drive\u2019s storage space into compartments known as clusters, enabling individual files to be tracked.<\/p>\n

This also helps monitor the available free space on the drive<\/a>.<\/p>\n

Each file system has its own unique features and organizes the drive differently, thus determining its compatibility and efficiency.<\/p>\n

The file system also specifies what attributes saved files can have; for instance, how the files can be named, what size they can be, or what permissions they can have.<\/p>\n

FAT32 is the oldest and, therefore, the most ubiquitous of the three file systems. Years later, exFAT was created as a more versatile replacement suitable for handling larger files and drives.<\/p>\n

NTFS is the most advanced of the three. It is the default file system for the internal drive (system drive) of computers running the latest versions of Windows.<\/p>\n

\r\n\t
Every OS has its own proprietary set of file systems for formatting drives. NTFS, exFAT, and FAT32 are Microsoft-designed file systems. Mac has APFS, HFS+, and HFS. Linux has ZFS, ext4, JFS, ZFS, XFS, and Btrfs.<\/p>\n

Some of these file systems are cross-platform compatible, meaning that they can be used by other OSes, while some are not and would require the installation of third-party software. Some are licensed to OEMs, such as FAT32 and exFAT, allowing them to work with a broad range of electronic devices and embedded systems<\/a>. <\/div>\r\n<\/div>\n

What is FAT32?<\/div>\r\n <\/div>\r\n
<\/div>\r\n<\/div><\/h3>\n

FAT file systems (FAT8, FAT12, FAT16, and finally, FAT32) were the default file systems for Windows until NTFS was introduced in Windows XP.<\/p>\n

FAT is short for File Allocation Table, and 32 refers to 32-bit addressing. It first appeared with the Windows 95 OSR2 release back in 1996. It was a significant advancement at the time, replacing the older FAT16 file system that was primarily used in Windows 3.0 PCs.<\/p>\n

In those days, FAT16 was becoming increasingly inefficient in satisfying the growing need for larger-sized hard drives, and FAT32 was a welcome improvement.<\/p>\n

Due to the fact that FAT32 has been around for close to 30 years now, it is supported by a broad range of electronic devices\u2014from embedded systems to gaming consoles, smart TVs, media players, and cameras, as well as Windows, Mac, and Linux computers.<\/p>\n

Practically, almost anything that has a USB port or memory card slot will work with drives formatted with this file system. Some flash drives and SD cards come pre-formatted with FAT32. It is the official file system for SD and SDHC cards that are less than 32 GB in size.<\/p>\n

However, because it\u2019s so old, it is limited in what it can do:<\/p>\n
