NAME

ntfstruncate - truncate a file on an NTFS volume

SYNOPSIS

ntfstruncate [ options ] device file [attr-type [ attr-name ]] new-length

DESCRIPTION

ntfstruncate truncates (or extends) a specified attribute belonging to a file or directory, to a specified length.

OPTIONS

Below is a summary of all the options that ntfstruncate 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.
-f , --force

This will override some sensible defaults, such as not using a mounted volume. Use this option with caution.

-h , --help

Show a list of options with a brief description of each one.

-l

Display licensing information.

-n , --no-action

Simulate the truncation without actually write to device.

-q , --quiet

Suppress some debug/warning/error messages.

-v , --verbose

Display more debug/warning/error messages.

-V , --version

Show the version number, copyright and license of ntfstruncate .

attr-type

Define a particular attribute type to be truncated (advanced use only). By default, the unnamed $DATA attribute (the contents of a plain file) will be truncated. The attribute has to be specified by a number in decimal or hexadecimal :

attr-name

Define the name of the particular attribute type to be truncated (advanced use only).

new-length

Specify the target size of the file. It will be rounded up to a multiple of the cluster size. A suffix of K, M, G, T, P or E may be appended to mean a multiplicative factor of a power of 1000. Similarly a suffix of Ki, Mi, Gi, Ti, Pi or Ei may be appended to mean a multiplicative factor of a power of 1024.

EXAMPLES

Resize to 100MB the file database.db located in the Data directory which is at the root of an NTFS file system.

ntfstruncate /dev/sda1 Data/database.db 100M
