NAME
ntfs-3g - Third Generation NTFS Driver
SYNOPSIS
ntfs-3g device mount_point [-o options]
DESCRIPTION
ntfs-3g is a user space NTFS driver, which can create, remove, rename
files, directories, hard links, or streams; it can read and write
files, including streams and sparse files; it can handle special files
like symbolic links, devices, and FIFOs; moreover it can also read com-
pressed files.
OPTIONS
Below is a summary of the options that ntfs-3g accepts.
uid=, gid=, umask=
Provide default owner, group, and access mode mask. These
options work as documented in mount(8). By default, the
files/directories are owned by user that mounted volume and
he/she has read and write permissions, as well as browse permis-
sion for directories. No one else has any access permissions.
I.e. the mode on all files is by default rw------- and for
directories rwx------, a consequence of the default fmask=0177
and dmask=0077. Using a umask of zero will grant all permis-
sions to everyone, i.e. all files and directories will have mode
rwxrwxrwx.
fmask=, dmask=
Instead of specifying umask which applies both to files and
directories, fmask applies only to files and mask only to direc-
tories.
show_sys_files
If show_sys_files is specified, show the system files in direc-
tory listings. Otherwise the default behaviour is to hide the
system files. Note that even when show_sys_files is specified,
"$MFT" may will not be visible due to bugs in glibc. Further-
more, note that irrespectively of show_sys_files, all files are
accessible by name, i.e. you can always do "ls -l '$UpCase'" for
example to show the system file containing the Unicode upcase
table.
default_permissions
By default FUSE doesn't check file access permissions, the
filesystem is free to implement it's access policy or leave it
to the underlying file access mechanism (e.g. in case of network
filesystems). This option enables permission checking,
restricting access based on file mode. This is option is usu-
ally useful together with the 'allow_other' mount option.
allow_other
This option overrides the security measure restricting file
access to the user mounting the filesystem. This option is by
default only allowed to root, but this restriction can be
removed with a configuration option described in the previous
section.
large_read
Issue large read requests. This can improve performance for
some filesystems, but can also degrade performance. This option
is mostly useful on 2.4.X kernels, as on 2.6 kernels requests
size is automatically determined for optimum performance.
max_read=
With this option the maximum size of read operations can be set.
The default is infinite. Note that the size of read requests is
limited anyway to 32 pages (which is 128kbyte on i386).
force Force mount even if errors occurred. Use this option only if you
know what are you doing.
ro Mount filesystem read-only.
no_def_opts
By default ntfs-3g acts as "default_permissions,allow_other" was
passed to it, this option cancel this behaviour.
silent Do nothing on chmod and chown operations, but do not return
error.
locale=
You can set locale with this option. It's useful if locale envi-
ronment variables are not set before partitions had been mounted
from /etc/fstab.
streams_interface=
This option controls how the user can access named data streams.
It can be set to, one of none, windows or xattr. If the option
is set to none, the user will have no access to the named data
streams. If it's set to windows, then the user can access them
just like in Windows (eg. cat file:stream). If it's set to
xattr, then the named data streams are mapped to xattrs and user
can manipulate them using {get,set}fattr utilities.
debug Makes ntfs-3g to not detach from terminal and print a lot of
debug output from libntfs-3g and FUSE.
no_detach
Same as above but with less debug output.
DATA STREAMS
All data on NTFS is stored in streams. Every file has exactly one
unnamed data stream and can have many named data streams. The size of
a file is the size of its unnamed data stream. By default, ntfs-3g
will only read the unnamed data stream.
By using the options "streams_interface=windows", you will be able to
read any named data streams, simply by specifying the stream's name
after a colon. For example:
cat some.mp3:artist
Windows applications don't, consistently, allow you to read named data
streams, so you are recommended to use tools like FAR, or utils from
Cygwin.
Named data streams act like normals files, so you can read from them,
write to them and even delete them (using rm). You can list all the
named data streams a file has by getting the "ntfs.streams.list"
extended attribute.
EXAMPLES
Mount /dev/hda1 to /mnt/windows using ntfs-3g:
ntfs-3g /dev/hda1 /mnt/windows
Read-only mount /dev/hda5 to /home/user/mnt and make user with uid 1000
to be owner of all files:
ntfs-3g /dev/hda5 /home/user/mnt -o ro,uid=1000
/etc/fstab entry for above:
/dev/hda5 /home/user/mnt ntfs-3g ro,uid=1000 0 0
Umount /mnt/windows:
fusermount -u /mnt/windows
