NTFS-3G is an open-source cross-platform implementation of the Microsoft Windows NTFS file system with read/write support. NTFS-3G often uses the , 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, MorphOS, Minix, macOS and OpenBSD. 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", while Tuxera NTFS is the proprietary version. In 2021, Linus Torvalds merged a different NTFS implementation called NTFS3 into the Linux kernel 5.15. NTFS-3G supports all operations for writing files: files of any size can be created, modified, renamed, moved, or deleted on NTFS partitions. is supported, as well as system-level . Support to modify access control lists and s is available. NTFS partitions are mounted using the (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. 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. According to its own information, the company Tuxera Ltd was founded in 2008 by Szabolcs Szakacsits, because more and more requests from well-known companies regarding the integration into their products made this step necessary. On its website, the company offers customized versions as Tuxera NTFS for Embedded Systems. NTFS-3G supports partial NTFS , so if an unexpected computer failure leaves the file system in an inconsistent state, the volume can be repaired.

Filesystem in Userspace

Filesystem in Userspace (FUSE) is a software interface for Unix and Unix-like computer operating systems that lets non-privileged users create their own s without editing kernel code. This is achieved by running file system code in user space while the FUSE module provides only a bridge to the actual kernel interfaces. FUSE is available for Linux, FreeBSD, OpenBSD, NetBSD (as puffs), OpenSolaris, Minix 3, macOS, and Windows. FUSE is free software originally released under the terms of the GNU General Public License and the GNU Lesser General Public License.

Access-control list

In computer security, an access-control list (ACL) is a list of permissions associated with a system resource (object or facility). An ACL specifies which users or system processes are granted access to resources, as well as what operations are allowed on given resourcess. Each entry in a typical ACL specifies a subject and an operation. For instance, If a file object has an ACL that contains , this would give Alice permission to read and write the file and give Bob permission only to read it.
