[options] device source_file destination
will overwrite file on an NTFS volume. At present
can't create new files.
can be either file or directory. In case if
is directory specified by name then
is copied into this directory, in case if
is directory and specified by inode number then unnamed data attribute is
created for this inode and
is copied into it (WARNING: it's unusual to have unnamed data streams in the
directories, think twice before specifying directory by inode number).
Below is a summary of all the options that
accepts. Nearly all options have two equivalent names. The short name is

Any single letter options, that don't take an argument, can be combined into a

Long named options can be abbreviated to any unique prefix of their name.
- -a, --attribute NUM

- -i, --inode
as inode number.
- -N, --attr-name NAME
Write to attribute with this name.
- -n, --no-action
Use this option to make a test run before doing the real copy operation.
Volume will be opened read-only and no write will be done.
- -f, --force
This will override some sensible defaults, such as not working with a mounted
volume. Use this option with caution.
- -h, --help
Show a list of options with a brief description of each one.
- -q, --quiet
Suppress some debug/warning/error messages.
- -V, --version
Show the version number, copyright and license

All data on NTFS is stored in streams, which can have names. A file can have
more than one data streams, but exactly one must have no name. The size of a
file is the size of its unnamed data stream. Usually when you don't specify
stream name you are access to unnamed data stream. If you want access to named
data stream you need to add ":stream_name" to the filename. For example: by
opening "some.mp3:artist" you will open stream "artist" in "some.mp3". But
windows usually prevent you from accessing to named data streams, so you need
to use some program like FAR or utils from cygwin to access named data streams.
Copy new_boot.ini from /home/user as boot.ini to the root of an /dev/hda1 NTFS
Copy myfile to C:\some\path\myfile:stream (assume that /dev/hda1 letter in
windows is C):
ntfscp /dev/hda1 /home/user/new_boot.ini boot.ini
ntfscp -N stream /dev/hda1 myfile /some/path
