The NTFS-3G driver is an open source, freely available NTFS driver for Linux with read and write support. It provides safe and fast handling of the Windows 2000/XP/2003/Vista/7 file systems. Most POSIX file system operations are supported, including full file ownership and access right support. The purpose of the project is to develop, continuously quality test and support a trustable, feature rich and high performance solution for hardware platforms and operating systems whose users need to reliably interoperate with NTFS. Besides this practical goal, the project also aims to explore the limits of a hybrid, kernel/user space file system driver approach. Performance, reliability and feature richness per invested effort are being examined. The driver is in STABLE status.
