Overview
16+
========
17+
18+
NTFS is a Linux kernel filesystem driver that provides full read and write
19+
support for NTFS volumes. It is designed for high performance, modern
20+
kernel infrastructure (iomap, folio), and stable long-term maintenance.
21+
22+
23+
Utilities support
24+
=================
25+
26+
The NTFS utilities project, called ntfsprogs-plus, provides mkfs.ntfs,
27+
fsck.ntfs, and other related tools (e.g., ntfsinfo, ntfsclone, etc.) for
28+
creating, checking, and managing NTFS volumes. These utilities can be used
29+
for filesystem testing with xfstests as well as for recovering corrupted
30+
NTFS devices.
31+
32+
The project is available at:
33+
34+
https://github.com/ntfsprogs-plus/ntfsprogs-plus
35+
36+
37+
Supported mount options
38+
=======================
39+
40+
The NTFS driver supports the following mount options:
41+
42+
======================= ====================================================
43+
iocharset=name Character set to use for converting between
44+
the encoding is used for user visible filename and
45+
16 bit Unicode characters.
46+
47+
nls=name Deprecated option. Still supported but please use
48+
iocharset=name in the future.
49+
50+
uid=
51+
gid=
52+
umask= Provide default owner, group, and access mode mask.
53+
These options work as documented in mount(8). By
54+
default, the files/directories are owned by root
55+
and he/she has read and write permissions, as well
56+
as browse permission for directories. No one else
57+
has any access permissions. I.e. the mode on all
58+
files is by default rw------- and
59+
for directories rwx------, a consequence of
60+
the default fmask=0177 and dmask=0077.
61+
Using a umask of zero will grant all permissions to
62+
everyone, i.e. all files and directories will have
63+
mode rwxrwxrwx.
64+
65+
fmask=
66+
dmask= Instead of specifying umask which applies both to
67+
files and directories, fmask applies only to files
68+
and dmask only to directories.
69+
70+
showmeta=<BOOL>
71+
show_sys_files=<BOOL> If show_sys_files is specified, show the system
72+
files in directory listings. Otherwise the default
73+
behaviour is to hide the system files.
74+
Note that even when show_sys_files is specified,
75+
"$MFT" will not be visible due to bugs/mis-features
76+
in glibc. Further, note that irrespective of
77+
show_sys_files, all files are accessible by name,
78+
i.e. you can always do "ls -l \$UpCase" for example
79+
to specifically show the system file containing
80+
the Unicode upcase table.
81+
82+
case_sensitive=<BOOL> If case_sensitive is specified, treat all filenames
83+
as case sensitive and create file names in
84+
the POSIX namespace (default behavior). Note,
85+
the Linux NTFS driver will never create short
86+
filenames and will remove them on rename/delete of
87+
the corresponding long file name. Note that files
88+
remain accessible via their short file name, if it
89+
exists.
90+
91+
nocase=<BOOL> If nocase is specified, treat filenames
92+
case-insensitively.
93+
94+
disable_sparse=<BOOL> If disable_sparse is specified, creation of sparse
95+
regions, i.e. holes, inside files is disabled for
96+
the volume (for the duration of this mount only).
97+
By default, creation of sparse regions is enabled,
98+
which is consistent with the behaviour of
99+
traditional Unix filesystems.
100+
101+
errors=opt Specify NTFS behavior on critical errors: panic,
102+
remount the partition in read-only mode or
103+
continue without doing anything (default behavior).
104+
105+
mft_zone_multiplier= Set the MFT zone multiplier for the volume (this
106+
setting is not persistent across mounts and can be
107+
changed from mount to mount but cannot be changed
108+
on remount). Values of 1 to 4 are allowed, 1 being
109+
the default. The MFT zone multiplier determines
110+
how much space is reserved for the MFT on the
111+
volume. If all other space is used up, then the
112+
MFT zone will be shrunk dynamically, so this has no
113+
impact on the amount of free space. However, it
114+
can have an impact on performance by affecting
115+
fragmentation of the MFT. In general use the
116+
default. If you have a lot of small files then use
117+
a higher value. The values have the following
118+
meaning:
119+
120+
===== =================================
121+
Value MFT zone size (% of volume size)
122+
===== =================================
123+
1 12.5%
124+
2 25%
125+
3 37.5%
126+
4 50%
127+
===== =================================
128+
129+
Note this option is irrelevant for read-only mount.
130+
131+
preallocated_size= Set preallocated size to optimize runlist merge
132+
overhead with small chunck size.(64KB size by
133+
default)
134+
135+
acl=<BOOL> Enable POSIX ACL support. When specified, POSIX
136+
ACLs stored in extended attributes are enforced.
137+
Default is off. Requires kernel config
138+
NTFS_FS_POSIX_ACL enabled.
139+
140+
sys_immutable=<BOOL> Make NTFS system files (e.g. $MFT, $LogFile,
141+
$Bitmap, $UpCase, etc.) immutable to user initiated
142+
modifications for extra safety. Default is off.
143+
144+
nohidden=<BOOL> Hide files and directories marked with the Windows
145+
"hidden" attribute. By default hidden items are
146+
shown.
147+
148+
hide_dot_files=<BOOL> Hide names beginning with a dot ("."). By default
149+
dot files are shown. When enabled, files and
150+
directories created with a leading '.' will be
151+
hidden from directory listings.
152+
153+
windows_names=<BOOL> Refuse creation/rename of files with characters or
154+
reserved device names disallowed on Windows (e.g.
155+
CON, NUL, AUX, COM1, LPT1, etc.). Default is off.
156+
discard=<BOOL> Issue block device discard for clusters freed on
157+
file deletion/truncation to inform underlying
158+
storage.
159+

NTFS is the file system of Microsoft Windows NT, 2000, XP and 2003.
8+
This allows you to mount devices formatted with the ntfs file system.

ntfs.

help
17+
If you are experiencing any problems with the NTFS file system, say
18+
Y here. This will result in additional consistency checks to be
19+
performed by the driver as well as additional debugging messages to
20+
be written to the system log. Note that debugging messages are
21+
disabled by default. To enable them, supply the option debug_msgs=1
22+
at the kernel command line when booting the kernel or as an option
23+
to insmod when loading the ntfs module. Once the driver is active,
24+
you can enable debugging messages by doing (as root):
25+
echo 1 > /proc/sys/fs/ntfs-debug
26+
Replacing the "1" with "0" would disable debug messages.
27+
28+
If you leave debugging messages disabled, this results in little
29+
overhead, but enabling debug messages results in very significant
30+
slowdown of the system.
31+
32+
When reporting bugs, please try to have available a full dump of
33+
debugging messages while the misbehaviour was occurring.

POSIX Access Control Lists (ACLs) support additional access rights
41+
for users and groups beyond the standard owner/group/world scheme.
42+
43+
This option enables ACL support for ntfs, providing functional parity
44+
with ntfs3 drivier.
45+
46+
NOTE: this is linux only feature. Windows will ignore these ACLs.
47+
48+
If you don't know what Access Control Lists are, say N.
