3 tristate "NTFS file system support"
7 NTFS is the file system of Microsoft Windows NT, 2000, XP and 2003.
9 Saying Y or M here enables read support. There is partial, but
10 safe, write support available. For write support you must also
11 say Y to "NTFS write support" below.
13 There are also a number of user-space tools available, called
14 ntfsprogs. These include ntfsundelete and ntfsresize, that work
15 without NTFS support enabled in the kernel.
17 This is a rewrite from scratch of Linux NTFS support and replaced
18 the old NTFS code starting with Linux 2.5.11. A backport to
19 the Linux 2.4 kernel series is separately available as a patch
20 from the project web site.
22 For more information see <file:Documentation/filesystems/ntfs.rst>
23 and <http://www.linux-ntfs.org/>.
25 To compile this file system support as a module, choose M here: the
26 module will be called ntfs.
28 If you are not using Windows NT, 2000, XP or 2003 in addition to
29 Linux on your computer it is safe to say N.
32 bool "NTFS debugging support"
35 If you are experiencing any problems with the NTFS file system, say
36 Y here. This will result in additional consistency checks to be
37 performed by the driver as well as additional debugging messages to
38 be written to the system log. Note that debugging messages are
39 disabled by default. To enable them, supply the option debug_msgs=1
40 at the kernel command line when booting the kernel or as an option
41 to insmod when loading the ntfs module. Once the driver is active,
42 you can enable debugging messages by doing (as root):
43 echo 1 > /proc/sys/fs/ntfs-debug
44 Replacing the "1" with "0" would disable debug messages.
46 If you leave debugging messages disabled, this results in little
47 overhead, but enabling debug messages results in very significant
48 slowdown of the system.
50 When reporting bugs, please try to have available a full dump of
51 debugging messages while the misbehaviour was occurring.
54 bool "NTFS write support"
56 depends on PAGE_SIZE_LESS_THAN_64KB
58 This enables the partial, but safe, write support in the NTFS driver.
60 The only supported operation is overwriting existing files, without
61 changing the file length. No file or directory creation, deletion or
62 renaming is possible. Note only non-resident files can be written to
63 so you may find that some very small files (<500 bytes or so) cannot
66 While we cannot guarantee that it will not damage any data, we have
67 so far not received a single report where the driver would have
68 damaged someones data so we assume it is perfectly safe to use.
70 Note: While write support is safe in this version (a rewrite from
71 scratch of the NTFS support), it should be noted that the old NTFS
72 write support, included in Linux 2.5.10 and before (since 1997),
75 This is currently useful with TopologiLinux. TopologiLinux is run
76 on top of any DOS/Microsoft Windows system without partitioning your
77 hard disk. Unlike other Linux distributions TopologiLinux does not
78 need its own partition. For more information see
79 <http://topologi-linux.sourceforge.net/>
81 It is perfectly safe to say N here.
