NTFS3
=====

Summary and Features
====================
-NTFS3 is fully functional NTFS Read-Write driver. The driver works with
-NTFS versions up to 3.1, normal/compressed/sparse files
-and journal replaying. File system type to use on mount is 'ntfs3'.
+NTFS3 is fully functional NTFS Read-Write driver. The driver works with NTFS
+versions up to 3.1. File system type to use on mount is *ntfs3*.
- This driver implements NTFS read/write support for normal, sparse and
compressed files.
-- Supports native journal replaying;
-- Supports extended attributes
- Predefined extended attributes:
- - 'system.ntfs_security' gets/sets security
- descriptor (SECURITY_DESCRIPTOR_RELATIVE)
- - 'system.ntfs_attrib' gets/sets ntfs file/dir attributes.
- Note: applied to empty files, this allows to switch type between
- sparse(0x200), compressed(0x800) and normal;
+- Supports native journal replaying.
- Supports NFS export of mounted NTFS volumes.
+- Supports extended attributes. Predefined extended attributes:
+
+ - *system.ntfs_security* gets/sets security
+
+ Descriptor: SECURITY_DESCRIPTOR_RELATIVE
+
+ - *system.ntfs_attrib* gets/sets ntfs file/dir attributes.
+
+ Note: Applied to empty files, this allows to switch type between
+ sparse(0x200), compressed(0x800) and normal.
Mount Options
=============
The list below describes mount options supported by NTFS3 driver in addition to
-generic ones.

+this table marked with no it means default is without **no**.

-acl Support POSIX ACLs (Access Control Lists). Effective if
- supported by Kernel. Not to be confused with NTFS ACLs.
- The option specified as acl enables support for POSIX ACLs.
+ * - force
+ - Forces the driver to mount partitions even if volume is marked dirty.

-noatime All files and directories will not update their last access
- time attribute if a partition is mounted with this parameter.
- This option can speed up file system operation.

+- Full journaling support over JBD. Currently journal replaying is supported
