NAME

     ewfexport -- exports media data stored in EWF files


SYNOPSIS

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


DESCRIPTION

     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), win-
             dows-874, windows-932, windows-936, windows-949, windows-950,
             windows-1250, windows-1251, windows-1252, windows-1253, win-
             dows-1254, windows-1255, windows-1256, windows-1257 or win-
             dows-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 compres-
             sion method options: deflate (default) 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

     -j jobs
             the number of concurrent processing jobs (threads), where a num-
             ber of 0 represents single-threaded mode (default is 4 if multi-
             threaded mode is supported).

     -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 later formats
             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 data chunk functions instead of the buffered read and
             write functions.


ENVIRONMENT

     None


FILES

EXAMPLES

     ewfexport will ask the information it needs.

     # ewfexport floppy.E01
     ewfexport 20160325

     Information for export required, please provide the necessary input
     Export to format (raw, files, ewf, smart, ftk, encase1, encase2, encase3, encase4, encase5, encase6, encase7, encase7-v2, linen5, linen6, linen7, ewfx) [raw]:
     Target path and filename without extension or - for stdout: floppy
     Evidence segment file size in bytes (1.0 MiB <= value <= 7.9 EiB) [1.4 GiB]:
     Start export at offset (0 <= value <= 1474560) [0]:
     Number of bytes to export (0 <= value <= 1474560) [1474560]:

     This could take a while.

     Status: at 2%.

             exported 1.4 MiB (1474560 bytes) of total 1.4 MiB (1474560 bytes).
             completion in 1 second(s) with 1 MiB/s (1474560 bytes/second).

     Export completed at: Sun Aug  5 19:19:41 2012

     Written: 1.4 MiB (1474560 bytes) in 1 second(s) with 1 MiB/s (1474560 bytes/second).
     MD5 hash calculated over data:          ae1ce8f5ac079d3ee93f97fe3792bda3


DIAGNOSTICS

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