.SH NAME
ntfs-3g \- Third Generation NTFS Driver
.SH SYNOPSIS
.B ntfs-3g
.I device mount_point
[\fB\-o options\fR]
.SH DESCRIPTION
\fBntfs-3g\fR 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
compressed files.
.SH OPTIONS
Below is a summary of the options that \fBntfs-3g\fR accepts.
.TP
.B 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 permission 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 permissions to
everyone, i.e. all files and directories will have mode
rwxrwxrwx.
.TP
.B fmask=, dmask=
Instead of specifying umask which applies both to
files and directories, fmask applies only to files and
mask only to directories.
.TP
.B show_sys_files
If show_sys_files is specified, show the system files
in directory listings.  Otherwise the default behaviour
is to hide the system files.
Note that even when show_sys_files is specified, "$MFT"
may will not be visible due to bugs in glibc.
Furthermore, note that irrespectively of show_sys_files, all
files are accessible by name, i.e. you can always do
"ls \-l '$UpCase'" for example to show the system file 
containing the Unicode upcase table.
.TP
.B 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 usually useful
together with the 'allow_other' mount option.
.TP
.B 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.
.TP
.B 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.
.TP
.B 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).
.TP
.B force
Force mount even if errors occurred. Use this option only if you know what
are you doing.
.TP
.B ro
Mount filesystem read\-only.
.TP
.B no_def_opts
By default ntfs-3g acts as "default_permissions,allow_other" was passed to it,
this option cancel this behaviour.
.TP
.B silent
Do nothing on chmod and chown operations, but do not return error.
.TP
.B locale=
You can set locale with this option. It's useful if locale environment variables
are not set before partitions had been mounted from /etc/fstab.
.TP
.B streams_interface=
This option controls how the user can access named data streams.  It can be set
to, one of \fBnone\fR, \fBwindows\fR or \fBxattr\fR. If the option is set to
\fBnone\fR, the user will have no access to the named data streams.  If it's set
to \fBwindows\fR, then the user can access them just like in Windows (eg. cat
file:stream). If it's set to \fBxattr\fR, then the named data streams are
mapped to xattrs and user can manipulate them using \fB{get,set}fattr\fR
utilities.
.TP
.B debug
Makes ntfs-3g to not detach from terminal and print a lot of debug output from
libntfs-3g and FUSE.
.TP
.B no_detach
Same as above but with less debug output.
.SH 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, \fBntfs-3g\fR will only read
the unnamed data stream.
.PP
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:
.RS
.sp
cat some.mp3:artist
.sp
.RE
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.
.PP
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.
.SH EXAMPLES
Mount /dev/hda1 to /mnt/windows using ntfs-3g:
.RS
.sp
.B ntfs-3g /dev/hda1 /mnt/windows
.sp
.RE
Read\-only mount /dev/hda5 to /home/user/mnt and make user with uid 1000 to be
owner of all files:
.RS
.sp
.B ntfs-3g /dev/hda5 /home/user/mnt \-o ro,uid=1000
.sp
.RE
/etc/fstab entry for above:
.RS
.sp
.B /dev/hda5 /home/user/mnt ntfs\-3g ro,uid=1000 0 0
.sp
.RE
Umount /mnt/windows:
.RS
.sp
.B fusermount \-u /mnt/windows
.sp
