ewfexportexports 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:

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
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
the number of bytes to export
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
calculate additional digest (hash) types besides md5, options: sha1 (not used for raw and files formats)
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.
shows this help
logs export errors and the digest (hash) to the log filename
the offset to start the export (default is 0)
the process buffer size (default is the chunk size)
swap byte pairs of the media data (from AB to BA) (use this for big to little endian conversion and vice versa)
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)
the target file to export to, use - for stdout (default is export) stdout is only supported for the raw format
unattended mode (disables user interaction)
verbose output to stderr
print version
zero sectors on checksum error (mimic EnCase like behavior)
use the chunk data instead of the buffered read and write functions.



ewfexport will ask the information it needs.

Errors, verbose and debug output are printed to stderr when verbose output -v is enabled. Verbose and debug output are only printed when enabled at compilation.
