NAME

     ewfexport -- exports media data stored in EWF files

SYNOPSIS

     ewfexport [-A codepage] [-B amount_of_bytes] [-c compression_type] [-d digest_type] [-f format] [-l log_filename] [-o offset]
	       [-p process_buffer_size] [-S segment_file_size] [-t target] [-hqsuvVw] 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 support the Expert Witness Compression Format (EWF).  libewf supports both
     the SMART format (EWF-S01) and the EnCase format (EWF-E01).  libewf currently does not support the Logical Volume format (EWF-L01). EWF-X is
     an expirimental format intended for testing purposes to enhance the EWF format.  libewf allows you to read and write media data in the EWF
     format.

     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-1250, windows-1251, windows-1252, windows-1253, win-
	     dows-1254, windows-1255, windows-1256, windows-1257, windows-1258

     -B amount_of_bytes
	     the amount of bytes to export

     -c compression_type
	     the compression type, options: none (default), empty-block, fast, best (not used for raw format)

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

     -f format
	     the file format to write to, options: raw (default), ewf, smart, ftk, encase1, encase2, encase3, encase4, encase5, encase6, linen5,
	     linen6, 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 encase6 format and 1.9 GiB for other
	     formats) (not used for raw 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      wipe sectors on CRC error (mimic EnCase like behavior)

ENVIRONMENT

     None

FILES

     None

EXAMPLES

     ewfexport will ask the information it needs.

     # ewfexport floppy.E01
     ewfexport 20090229 (libewf 20090229, libuna 20090124, zlib 1.2.3, libcrypto 0.9.8g, libuuid)

     Information for export required, please provide the necessary input
     Export to file format (raw, ewf, smart, ftk, encase1, encase2, encase3, encase4, encase5, encase6, linen5, linen6, ewfx) [raw]:
     Target path and filename with extension or - for stdout: floppy.raw
     Start export at offset (0 >= value >= 1474560) [0]:
     Amount of bytes to export (0 >= value >= 1474560) [1474560]:

     Export started at: Sat Feb 28 19:19:40 2009

     This could take a while.

     Status: at 2%.
	     exported 32 kB (32768 bytes) of total 1.4 MiB (1474560 bytes).

	   ...

     Status: at 100%.
	     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: Sat Feb 28 19:19:41 2009

     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 output -v is enabled. Verbose and debug output are only printed when
     enabled at compilation.
