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 $DATA attribute (the contents of a plain file) will be truncated. The attribute has to be specified by a number in decimal or hexadecimal : +-------------------------------------------+ |Hex Decimal Name | |0x10 16 "$STANDARD_INFORMATION" | |0x20 32 "$ATTRIBUTE_LIST" | |0x30 48 "$FILE_NAME" | |0x40 64 "$OBJECT_ID" | |0x50 80 "$SECURITY_DESCRIPTOR" | |0x60 96 "$VOLUME_NAME" | |0x70 112 "$VOLUME_INFORMATION" | |0x80 128 "$DATA" | |0x90 144 "$INDEX_ROOT" | |0xA0 160 "$INDEX_ALLOCATION" | |0xB0 176 "$BITMAP" | |0xC0 192 "$REPARSE_POINT" | |0xD0 208 "$EA_INFORMATION" | |0xE0 224 "$EA" | |0xF0 240 "$PROPERTY_SET" | |0x100 256 "$LOGGED_UTILITY_STREAM" | +-------------------------------------------+ 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
