3 tristate "NTFS file system support"
6 NTFS is the file system of Microsoft Windows NT, 2000, XP and 2003.
8 Saying Y or M here enables read support. There is partial, but
9 safe, write support available. For write support you must also
10 say Y to "NTFS write support" below.
12 There are also a number of user-space tools available, called
13 ntfsprogs. These include ntfsundelete and ntfsresize, that work
14 without NTFS support enabled in the kernel.
16 This is a rewrite from scratch of Linux NTFS support and replaced
17 the old NTFS code starting with Linux 2.5.11. A backport to
18 the Linux 2.4 kernel series is separately available as a patch
19 from the project web site.
21 For more information see <file:Documentation/filesystems/ntfs.rst>
22 and <http://www.linux-ntfs.org/>.
24 To compile this file system support as a module, choose M here: the
25 module will be called ntfs.
27 If you are not using Windows NT, 2000, XP or 2003 in addition to
28 Linux on your computer it is safe to say N.
31 bool "NTFS debugging support"
34 If you are experiencing any problems with the NTFS file system, say
35 Y here. This will result in additional consistency checks to be
36 performed by the driver as well as additional debugging messages to
37 be written to the system log. Note that debugging messages are
38 disabled by default. To enable them, supply the option debug_msgs=1
39 at the kernel command line when booting the kernel or as an option
40 to insmod when loading the ntfs module. Once the driver is active,
41 you can enable debugging messages by doing (as root):
42 echo 1 > /proc/sys/fs/ntfs-debug
43 Replacing the "1" with "0" would disable debug messages.
45 If you leave debugging messages disabled, this results in little
46 overhead, but enabling debug messages results in very significant
47 slowdown of the system.
49 When reporting bugs, please try to have available a full dump of
50 debugging messages while the misbehaviour was occurring.
53 bool "NTFS write support"
56 This enables the partial, but safe, write support in the NTFS driver.
58 The only supported operation is overwriting existing files, without
59 changing the file length. No file or directory creation, deletion or
60 renaming is possible. Note only non-resident files can be written to
61 so you may find that some very small files (<500 bytes or so) cannot
64 While we cannot guarantee that it will not damage any data, we have
65 so far not received a single report where the driver would have
66 damaged someones data so we assume it is perfectly safe to use.
68 Note: While write support is safe in this version (a rewrite from
69 scratch of the NTFS support), it should be noted that the old NTFS
70 write support, included in Linux 2.5.10 and before (since 1997),
73 This is currently useful with TopologiLinux. TopologiLinux is run
74 on top of any DOS/Microsoft Windows system without partitioning your
75 hard disk. Unlike other Linux distributions TopologiLinux does not
76 need its own partition. For more information see
77 <http://topologi-linux.sourceforge.net/>
79 It is perfectly safe to say N here.
