ntfscp - copy file to an NTFS volume.
ntfscp [options] device source_file destination
ntfscp will copy file to an NTFS volume. destination can be either file
or directory. In case if destination is directory specified by name
then source_file is copied into this directory, in case if destination
is directory and specified by inode number then unnamed data attribute
is created for this inode and source_file 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 ntfscp accepts. Nearly all
options have two equivalent names. The short name is preceded by - and
the long name is preceded by --. Any single letter options, that don't
take an argument, can be combined into a single command, e.g. -fv is
equivalent to -f -v. Long named options can be abbreviated to any
unique prefix of their name.
-a, --attribute NUM
Write to this attribute.
Treat destination as inode number.
Minimize fragmentation when allocating space to the attribute.
This is mostly useful when creating big files.
-N, --attr-name NAME
Write to attribute with this name.
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
This will override some sensible defaults, such as not working
with a mounted volume. Use this option with caution.

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 volume:
ntfscp /dev/hda1 /home/user/new_boot.ini boot.ini
Copy myfile to C:\some\path\myfile:stream (assume that /dev/hda1 letter
in windows is C):
ntfscp -N stream /dev/hda1 myfile /some/path
