mac下读写ntfs文件系统的工具NTFS-3G

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 FUSE file system interface, so it can run unmodified on many different operating systems. It is runnable on Linux,FreeBSD, NetBSD, OpenSolaris, BeOS, QNX, WinCE, Nucleus, VxWorks, Haiku,^[1] MorphOS, and Mac OS X.^[2] It is licensed under either the GNU General Public License or a proprietary 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 (Hungarian pronunciation: [ˈsɒboltʃ ˈsɒkɒtʃitʃ]), 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 Ltd., to further develop the code. NTFS-3G is now the free "community edition",^[1] while Tuxera NTFS is the proprietary version.

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, but there is no support for encryption.^[3] Support to modify access control lists and permissions is available.^[4] NTFS partitions are mounted using the Filesystem in Userspace(FUSE) interface.[edit]Features

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.^[5]

[edit]Performance

Benchmarks show that the driver's performance via FUSE is comparable to that of other filesystems' drivers in-kernel,^[6] provided that the CPU is powerful enough. On embedded or old systems, the high processor usage can severely limit performance.^[7]. Current versions often show 100% CPU utilization on dealing with big files on fragmented NTFS file systems ^[8].
