ewfexport — exports media data stored in EWF files


ewfexport [-A codepage] [-b number_of_sectors] [-B number_of_bytes] [-c compression_values]
[-d digest_type] [-f format] [-l log_filename] [-o offset]
[-p process_buffer_size] [-S segment_file_size] [-t target] [-hqsuvVwx] ewf_files


ewfexport is a utility to export media data stored in EWF files.

ewfexport is part of the libewf package. libewf is a library to access the Expert Witness
Compression Format (EWF).

ewf_files the first or the entire set of EWF segment files

The options are as follows:

-A codepage
the codepage of header section, options: ascii (default), windows-874, windows-932,
windows-936, windows-949, windows-950, windows-1250, windows-1251, windows-1252,
windows-1253, windows-1254, windows-1255, windows-1256, windows-1257 or windows-1258

-b number_of_sectors
the number of sectors to read at once (per chunk), options: 16, 32, 64 (default),
128, 256, 512, 1024, 2048, 4096, 8192, 16384 or 32768

-B number_of_bytes
the number of bytes to export

-c compression_values
specify the compression values as: level or method:level compression method options:
deflate (default), bzip2 (bzip2 is only supported by EWF2 formats) compression level
options: none (default), empty-block, fast or best

-d digest_type
calculate additional digest (hash) types besides md5, options: sha1 (not used for
raw and files formats)

-f format
the output format to write to, options: raw (default), files (restricted to logical
volume files), ewf, smart, ftk, encase1, encase2, encase3, encase4, encase5,
encase6, encase7, encase7-v2, linen5, linen6, linen7, ewfx.

-h shows this help

-l log_filename
logs export errors and the digest (hash) to the log filename

-o offset
the offset to start the export (default is 0)

-p process_buffer_size
the process buffer size (default is the chunk size)

-s swap byte pairs of the media data (from AB to BA) (use this for big to little endian
conversion and vice versa)

-S segment_file_size
the segment file size in bytes (default is 1.4 GiB) (minimum is 1.0 MiB, maximum is
7.9 EiB for raw, encase6 and encase7 format and 1.9 GiB for other formats) (not used
for files format)

-t target
the target file to export to, use - for stdout (default is export) stdout is only
supported for the raw format

-u unattended mode (disables user interaction)

-v verbose output to stderr

-V print version

-w zero sectors on checksum error (mimic EnCase like behavior)

-x use the chunk data instead of the buffered read and write functions.
