                 [-d  digest_type]  [-f  format]  [-l  log_filename]  [-o   offset]   [-p   process_buffer_size]

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), 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) 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.

ENVIRONMENT

       None

FILES

       None

EXAMPLES

       ewfexport will ask the information it needs.

       # ewfexport floppy.E01
       ewfexport 20120805

       Information for export required, please provide the necessary input

DIAGNOSTICS

       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.
