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 2007-02-21 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.

WHY YOU NEED MICROSOFT NTFS FOR MAC BY TUXERA
When it comes to Windows NTFS-formatted USB drives, Macs are only built for reading. That means you can open files stored on those drives, but you can’t edit, copy, move, or delete those files using your Mac. To write files, you need an add-on NTFS-driver.
Microsoft NTFS for Mac by Tuxera is easy-to-use software that makes this all possible.
Use external USB drives previously formatted in Windows
Swap drives regularly between Windows PCs and Macs
Seamless data exchange when dual booting Windows and macOS/OS X
Easy file handling when running Windows through a virtual machine
Easily swap and change drives
Use the same external USB drives no matter what you use—Windows PCs or Macs. Microsoft NTFS for Mac by Tuxera adds full read and write capability for Windows NTFS-formatted drives.
Preserve what’s important
Unexpected power cuts or unplugging a USB drive at the wrong time can cause data loss – or worse – damage the drive. Our market-leading fail-safe technology keeps your videos, pictures, and other files intact, plus prevents drive corruption.
