NTFS-3G is an open-sourcecross-platform implementation of the Microsoft WindowsNTFS file system with read/write support. NTFS-3G often uses the FUSEfile system interface, so it can run unmodified on many different operating systems. It is runnable on Linux, FreeBSD, NetBSD, OpenSolaris, illumos, BeOS, QNX, WinCE, Nucleus, VxWorks, Haiku,[1]MorphOS, Minix, macOS[2] and OpenBSD.[3][4] It is licensed under the GNU General Public License. It is a partial fork of ntfsprogs and is under active maintenance and development.
NTFS-3G was introduced by one of the senior Linux NTFS developers, Szabolcs Szakacsits, in July 2006. The first stable version was released on February 21, 2007, as version 1.0. The developers of NTFS-3G later formed a company, Tuxera Inc., to further develop the code. NTFS-3G is now the free 'community edition',[1][failed verification] while Tuxera NTFS is the proprietary version.
Features[edit]
NTFS-3G supports all operations for writing files: files of any size can be created, modified, renamed, moved, or deleted on NTFS partitions. Transparent compression is supported, as well as system-level encryption.[5] Support to modify access control lists and permissions is available.[6] NTFS partitions are mounted using the Filesystem in Userspace (FUSE) interface. NTFS-3G supports hard links, symbolic links, and junctions. With the help of NTFS reparse point plugins, it can be made to read chunk-deduplicated files, system-compressed files, and OneDrive files.[7] NTFS-3G provides complete support and translation of NTFS access control list (ACL) to POSIX ACL permissions. A 'usermap' utility is included to record the mapping from UIDs to Windows NT SIDs.
NTFS-3G supports partial NTFS journaling, so if an unexpected computer failure leaves the file system in an inconsistent state, the volume can be repaired. As of 2009, a volume having an unclean journal file is recovered and mounted by default. The ‘norecover’ mount option can be used to disable this behavior.[8]

Performance[edit]
Benchmarks show that the driver's performance via FUSE is comparable to that of other filesystems' drivers in-kernel,[9] provided that the CPU is powerful enough. On embedded or old systems, the high processor usage can severely limit performance. Tuxera sells optimized versions of the driver that claims to have improved CPU utilization for embedded systems and MacOS.[10]
The slowness of NTFS-3G (and FUSE in general) on embedded systems is attributed to the frequent context switching associated with FUSE calls. Some open-source methods provided to reduce this overhead include:[11]
- The underlying FUSE layer has an option called
big_writesto use larger blocks when writing. Using a larger block means fewer context switches. This is in fact a solution recommended by Tuxera.[12] A patch is available to use an even larger block.[13] - There is also a Linux kernel option called
lazytimeto reduce the writes on file access. - Synology Inc. uses a modified NTFS-3G on their NAS systems. It replaces the ntfs-3g inode caching
CACHE_NIDATA_SIZEwith a different mechanism with unsure benefit. (It also includes an alternative Security Identifier translation for the NAS.)
History[edit]
- NTFS-3G forked from the Linux-NTFS project on October 31, 2006.
- On February 21, 2007, Szabolcs Szakacsits announced 'the release of the first open-source, freely available, stable read/write NTFS driver, NTFS-3G 1.0.'
- On October 5, 2009, NTFS-3G for Mac was brought under the auspices of Tuxera Ltd. and a proprietary version called Tuxera NTFS for Mac was made available.[14]
- On April 12, 2011, it was announced that Ntfsprogs project was merged with NTFS-3G.[15]
- NTFS-3g added TRIM support in version 2015.3.14.

Tuxera Inc. is a Finnish software company that develops and sells file systems software. Its most popular products are Tuxera NTFS and Tuxera exFAT, both available on a number of platforms including Linux, Android, QNX and macOS. Tuxera's customers include a number of consumer electronics manufacturers in mobile phones, tablets, TVs, set-top boxes, automotive infotainment and storage markets.[1] Tuxera NTFS for Mac provides read/write connectivity to Windows-formatted hard drives for macOS.[2]
The company was founded in 2008 and is currently headquartered in Espoo, Finland. Tuxera's other offices are located in the US, South Korea,[3]Japan, Germany, Taiwan and China.
History[edit]
The origin of the company dates back to the open-source NTFS development in the late 1990s. NTFS had been introduced in 1993 by Microsoft as the file system for Windows NT. At that time Anton Altaparmakov emerged as the lead developer and maintainer of the Linux NTFS kernel driver. Meanwhile, Szabolcs Szakacsits continued to lead a platform-independent project under the name NTFS-3G. In 2006, NTFS-3G became the first driver to gain full read and write support. Commercial activity started in 2007 and the company was founded next year. In 2009 the company signed agreements with Microsoft,[4] which was followed by global expansion and establishing the collaboration with chipset vendors and software platform companies.[5]
In February 2011 Tuxera joined the Linux Foundation,[6] which was an expected step as for many years Tuxera has contributed to the Linux kernel.
In July 2019 Tuxera acquired Datalight,[7] to strengthen its internal storage offering and expertise in flash memory and flash management software.

NTFS-3G is the original free-software 'community edition' driver used widely in Linux distributions, including Fedora, Ubuntu, and others. On April 12, 2011 it was announced that Ntfsprogs project was merged with NTFS-3G.[11]
VelocityFS by Tuxera (formerly Tuxera Flash File System)[edit]
Tuxera also develops and commercializes its own proprietary Flash file system. Due to its fail-safe technology it can be found for instance in vehicles and cars, integrated with the event data recorder to make sure the data recorded from sensors is consistent even in case of a crash.[12]
Tuxera FAT+[edit]
In 2017, Tuxera introduced FAT+,[13] a file system implementation for Universal Flash Storage cards and removable storage that is compatible with FAT32 but without the file size limitation of 4 GiB. It is royalty free for UFS card host devices[14] and a standard recommended by the Universal Flash Storage Association.[15]
Consumer products[edit]
AllConnect[edit]
AllConnect is a mobile app that allows to stream music, photos and videos from Android devices to DLNA receivers (smart TVs, set-top-boxes, wireless speakers, etc.). It was launched on November 12, 2013 under the name of Streambels.[16]
Tuxera NTFS for Mac[edit]
Tuxera NTFS for Mac allows macOS computers to read and write NTFS partitions. By default, macOS provides only read access to NTFS partitions. The latest stable version of the driver is 2016, released in September 2016.[17] With the introduction of System Integrity Protection (SIP) by Apple in OS X El Capitan, usage of third-party software in Disk Utility is no longer possible. As a workaround, Tuxera NTFS for Mac ships together with Tuxera Disk Manager[18] to facilitate the format and maintenance of NTFS volumes in macOS. Currently the software supports 13 languages: Arabic, Simplified and Traditional Chinese, English, French, German, Italian, Japanese, Korean, Portuguese, Russian, Spanish and Turkish.[19] The software supports 64-bit kernels, including OS X El Capitan.[20] It supports NTFS extended attributes and works with virtualization and encryption solutions including Parallels Desktop and VMware Fusion.
