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,
windows-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

EXAMPLES¶
ewfexport will ask the information it needs.

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.
