iocharset=name

This option informs the driver how to interpret path strings and translate them to Unicode and back. If this option is not set, the default codepage will be used (CONFIG_NLS_DEFAULT).

Example: iocharset=utf8

uid=

gid=

umask=

Controls the default permissions for files/directories created after the NTFS volume is mounted.

dmask=

Instead of specifying umask which applies both to files and directories, fmask applies only to files and dmask only to directories.

fmask=

nohidden

Files with the Windows-specific HIDDEN (FILE_ATTRIBUTE_HIDDEN) attribute will not be shown under Linux.

sys_immutable

Files with the Windows-specific SYSTEM (FILE_ATTRIBUTE_SYSTEM) attribute will be marked as system immutable files.

hide_dot_files

Updates the Windows-specific HIDDEN (FILE_ATTRIBUTE_HIDDEN) attribute when creating and moving or renaming files. Files whose names start with a dot will have the HIDDEN attribute set and files whose names do not start with a dot will have it unset.

windows_names

Prevents the creation of files and directories with a name not allowed by Windows, either because it contains some not allowed character (which are the characters “ * / : < > ? \ | and those whose code is less than 0x20), because the name (with or without extension) is a reserved file name (CON, AUX, NUL, PRN, LPT1-9, COM1-9) or because the last character is a space or a dot. Existing such files can still be read and renamed.

discard

Enable support of the TRIM command for improved performance on delete operations, which is recommended for use with the solid-state drives (SSD).

force

Forces the driver to mount partitions even if volume is marked dirty. Not recommended for use.

sparse

Create new files as sparse.

showmeta

Use this parameter to show all meta-files (System Files) on a mounted NTFS partition. By default, all meta-files are hidden.

prealloc

Preallocate space for files excessively when file size is increasing on writes. Decreases fragmentation in case of parallel write operations to different files.

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.

ads

Enable access to alternate data streams, i.e. named $DATA attributes. A stream is addressed by appending a colon and the stream name to the file name. Reading the pseudo-stream query_streams returns the names of the streams attached to a file, one per line:

cat file:query_streams   # list stream names
cat file:ads1            # read a stream
touch file:ads2          # create a stream on an existing file
rm file:ads1             # remove a stream

Creating a file together with a stream in a single call, and renaming a stream, are not supported. Enabled by default.

nocase

Perform file name lookups case-insensitively.

delalloc

Delay block allocation for buffered writes until writeback, rather than allocating as each write is issued. This lets the driver allocate larger contiguous runs and reduces fragmentation.
