标  题: What’s the Difference Between FAT32, exFAT, and NTFS?
发信站: BBS 未名空间站 (Thu Nov  3 12:55:42 2016, 美东)

Whether you’re formatting an internal drive, external drive, USB flash
drive, or SD card, Windows will give you the choice of NTFS, FAT32, and
exFAT. The Format dialog in Windows doesn’t explain the difference, so we
will.

FAT32 is an older file system that’s largely relegated to USB flash drives
and other external drives. Windows uses NTFS for its system drive, and it’s
also ideal for other internal drives. exFAT is a modern replacement for
FAT32, and more devices support it than do NTFS — although it’s not as
widespread as FAT32.



FAT32
RELATED ARTICLE
Why Do Removable Drives Still Use FAT32 Instead of NTFS?
FAT32 is the oldest file system here. It was introduced all the way back in
Windows 95 to replace the older FAT16 file system.

This file system’s age has advantages and disadvantages. Because it’s so
old, it’s the de-facto standard. Flash drives you purchase will often come
formatted with FAT32 for maximum compatibility across not just modern
computers, but other devices like game consoles and anything with a USB port.

Limitations come with that age, however. Individual files on a FAT32 drive
can’t be over 4 GB in size — that’s the maximum. A FAT32 partition must
also be less than 8 TB, which is less of a limitations — but still a
noticeable one if you have a new, high-capacity mechanical drive.

While this file system is okay for USB flash drives and other external media
, you won’t want to use this for an internal drive. It lacks the
permissions and other security features built into the more modern NTFS file
system. Modern versions of Windows can no longer be installed to FAT32, and
must be installed onto drives formatted with NTFS.

Compatibility: Works with all versions of Windows, Mac, Linux, game consoles
, and practically anything with a USB port.

Limits: 4 GB maximum file size, 8 TB maximum partition size.

Ideal Use: Use it on removable drives for maximum compatibility with the
widest range of devices, assuming you don’t have any files 4 GB or larger
in size.

NTFS
NTFS is the modern file system Windows likes to use. When you install
Windows, it formats your system drive with the NTFS file system. NTFS has
file size and partition size limits that are so theoretically huge you won’
t run up against them. NTFS first appeared in consumer versions of Windows
with Windows XP.

Aside from these limitations, NTFS is packed with other modern features. It
supports file permissions for security, a change journal that can help
quickly recover errors if your computer crashes, shadow copies for backups,
encryption, disk quota limits, hard links, and other various features. Many
of these are crucial for an operating system drive — especially file
permissions.

Your Windows system partition must be NTFS. If you have a secondary drive
alongside Windows and you plan on installing programs to it, you should
probably go ahead and make it NTFS, too.

However, NTFS just isn’t as compatible with other operating systems. It’ll
work with all recent versions of Windows — all the way back to Windows XP
— but it has limited compatibility with other operating systems. By default
, Mac OS X can only read NTFS drives, not write to them. Some Linux
distributions may enable NTFS-writing support, but some may be read-only.
None of Sony’s PlayStation consoles support NTFS. Even Microsoft’s own
Xbox 360 can’t read NTFS drives, although the new Xbox One can. Other
devices are even less likely to support NTFS.

Compatibility: Works with all versions of Windows, but read-only with Mac by
default, and may be read-only by default with some Linux distributions.
Other devices — with the exception of Microsoft’s Xbox One — probably won
’t support NTFS.

Limits: No realistic file-size or partition size limits.

Ideal Use: Use it for your Windows system drive and other internal drives
that will just be used with Windows.

exFAT
RELATED ARTICLE
What File System Should I Use for My USB Drive?
exFAT was introduced in 2006, and was added to older versions of Windows
with updates to Windows XP and Windows Vista.

It’s a file system optimized for flash drives. It’s designed to be a
lightweight file system like FAT32 without all NTFS’s extra features and
overhead, but without FAT32’s limitations.

Like NTFS, exFAT has very large file size and partition size limits. This
means you can store files that are larger than 4 GB apiece on a flash drive
or SD card if it’s formatted with exFAT. exFAT is a strict upgrade over
FAT32, and should be the best choice for external drives where you want a
lightweight file system without FAT32’s file size limits.

exFAT is also more compatible than NTFS. While Mac OS X includes only read-
only support for NTFS, Macs offer full read-write support for exFAT. exFAT
drives can be accessed on Linux by installing the appropriate software.

While exFAT is compatible with Macs — and will be compatible with some
devices that don’t support NTFS, like digital cameras — it still isn’t
quite as compatible. Microsoft’s own Xbox 360 doesn’t support it, although
the Xbox One does. The PlayStation 3 doesn’t support exFAT drives,
although the PlayStation 4 reportedly does. Various other older devices may
only support FAT32 instead of exFAT.

Compatibility: Works with all versions of Windows and modern versions of Mac
OS X, but requires additional software on Linux. More devices support exFAT
than support NTFS, but some — particularly older ones — may only support
FAT32.

Limits: No realistic file-size or partition-size limits.

Ideal Use: Use it for USB flash drives and other external drives, especially
if you need files of over 4 GB in size. Assuming every device you want to
use the drive with supports exFAT, you should format your device with exFAT
instead of FAT32.

Usb Flash Drives

NTFS is ideal for internal drives, while exFAT is generally ideal for flash
drives. However, you may sometimes need to format an external drive with
FAT32 if exFAT isn’t supported on a device you need to use it with.
