File Systems Explained

When you first set up a hard drive for use with a computer, you have to format it using a file system. Different operating systems (like Windows, Mac OS X, and Linux) use different file systems to organize and store data, so you need to use the file system most applicable for your needs. Here are a few of the more popular file systems you'll see:
- NTFS: This is Windows' default file system. Windows can read and write to NTFS-formatted drives. OS X and Linux can only read NTFS-formatted drives, but not write to them—unless you have a third-party driver like NTFS-3G installed.
- FAT32: FAT32 is an older file system. You can't install newer versions of Windows on a FAT32 system, but it can be handy for external drives since it can be read and written to by Windows, OS X, and Linux. However, it has one major downside: You can only store files 4GB or smaller on a FAT32 drive, which means it isn't ideal for large files like movies.
- ExFAT: ExFAT is less commonly used, but is similar to FAT32 without the downsides. Both Windows and OS X can read and write ExFAT-formatted drives, and it can store files over 4GB. This makes it ideal for flash drives.
- HFS Plus: Also known as Mac OS Extended, this is OS X's default file system. OS X can read and write to it. If you're running Windows on your Mac with Boot Camp, you can read HFS Plus drives, but not write to them. A third party tool like Paragon HFS+ will allow any Windows system to read and write to HFS Plus drives.

These are just a few examples of popular file systems, and the only ones you'll really encounter as a Windows or Mac user. Which one you use depends on the drive and what you're using it for. For example, if you have an external drive you only use with Windows computers, you'll want to format it as NTFS. If you have a drive you're using with Windows PCs and Macs, ExFAT is probably the best option.
Note that when you format a hard drive, it erases all the content on your drive, so make sure you choose the right file system before you copy your data. In some cases, it's possible to convert your drive without losing files—like converting a hard drive from FAT32 to NTFS—but under most circumstances, the only way to change your file system is to erase the drive and format it from scratch.

So you've just bought a new external drive or flash drive, and you need to start using it. Note that we recommend formatting every drive you buy, even if it works when you plug it in—many external and flash drives come with extra software that, in our opinion, isn't very good, and formatting it removes that annoyance (not to mention gives you a bit of extra space on the drive).

When you purchase a brand-new hard drive, there’s no guarantee that it will be pre-formatted from the factory, nor is there any guarantee that it will come with the right file system. Optimization is another good reason for hard drive formatting. Data fragmentation remains an issue even in the era of mobile devices, and in some cases formatting is the fastest way how to solve it.

Regardless of why you want to format your hard drive, there are some considerations to be made before you begin. First and foremost, you need to decide which file system to use. Mac OS X uses the HFS Plus file system, while Windows uses the NTFS file system. Both Mac OS X and Windows also support the FAT32 file system, but we don’t recommend it for hard drives. Because FAT32 supports only up to 4 GB large files, it should be used only with flash drives. If you need to format external hard drive Mac or Windows, you may also consider the exFAT files system. Developed by Microsoft, this modern file system is optimized for situations where the NTFS file system is not a feasible solution, and the file size limit of the standard FAT32 file system is unacceptable.
