![]() It is set by default when a user mapping file is present and the permissions mount option is not set. This option is only available on specific builds. acl Enable setting Posix ACLs on created files and use them for access control. OPTIONS Below is a summary of the options that ntfs - 3 g accepts. You can list all the named data streams a file has by getting the ntfs. mp3 :artist Named data streams act like normal files, so you can read from them, write to them and even delete them ( using rm ). By using the option streams_interface = windows, with the ntfs - 3 g driver ( not possible with lowntfs - 3 g ), you will be able to read any named data streams, sim ‐ ply by specifying the stream name after a colon. By default, ntfs - 3 g will only read the unnamed data stream. The size of a file is the size of its unnamed data stream. Every file has exactly one unnamed data stream and can have many named data streams. Īlternate Data Streams (ADS) NTFS stores all data in streams. The option windows_names may be used to apply Windows restrictions to new file names. This is perfectly legal on Windows, though some application may get confused. This means that filenames are case sensitive and all characters are allowed except '/' and ' \0 '. ![]() While the ntfs - 3 g driver handles all of them, it always creates new files in the POSIX name ‐ space for maximum portability and interoperability reasons. Windows Filename Compatibility NTFS supports several filename namespaces : DOS, Win32 and POSIX. If ntfs - 3 g is set setuid - root then non - root users will be also able to mount volumes. Moreover, by defining a Win ‐ dows - to - Linux user mapping, the ownerships and permissions are even applied to Windows users and conversely. But, by setting the permissions option, you can benefit from the full ownership and permissions features as defined by POSIX. Doing so, all Windows users have full access to the files created by ntfs - 3 g. You can also assign permissions to a single user by using the uid and / or the gid options together with the umask, or fmask and dmask options. Īccess Handling and Security By default, files and directories are owned by the effective user and group of the mounting process, and everybody has full read, write, execution and direc ‐ tory browsing permissions. This can be achieved by issuing as an Administrator the Windows command which disables both hibernation and fast restart ‐ ing : powercfg / h off If either Windows is hibernated or its fast restart is enabled, partitions on internal disks are forced to be mounted in read - only mode. Moreover, the fast restart feature available on recent Windows systems has to be disabled. So, Windows may not be left in hibernation when starting Linux, in order to avoid inconsistencies. Windows hibernation and fast restarting On computers which can be dual - booted into Windows or Linux, Windows has to be fully shut down before booting into Linux, otherwise the NTFS file systems on internal disks may be left in an inconsistent state and changes made by Linux may be ignored by Windows. The volume to be mounted can be either a block device or an image file, either by using the mount command or starting the drive. It comes in two variants ntfs - 3 g and lowntfs - 3 g with a few differences mentioned below in relevant options descriptions. SYNOPSIS ntfs - 3 g ] volume mount_point mount - t ntfs - 3 g ] volume mount_point lowntfs - 3 g ] volume mount_point mount - t lowntfs - 3 g ] volume mount_pointĭESCRIPTION ntfs - 3 g is an NTFS driver, which can create, remove, rename, move files, directories, hard links, and streams it can read and write files, including streams, sparse files and transparently compressed files it can handle special files like symbolic links, devices, and FIFOs moreover it provides standard management of file ownership and permissions, including POSIX ACLs.
