Scalpel is an open source data carving tool.



scalpel [-b] [-c <config file>] [-d] [-e] [-h] [-i <file>]
[-n] [-o <outputdir>] [-O] [-p] [-q <clustersize>] [-r]
[-v] [-V] <imgfile> [<imgfile>] ...


-b  Carve files even if defined footers aren't discovered within
    maximum carve size for file type [foremost 0.69 compat mode].
-c  Choose configuration file.
-d  Generate header/footer database; will bypass certain optimizations
    and discover all footers, so performance suffers.  Doesn't affect
    the set of files carved.  **EXPERIMENTAL**
-e  Do nested header/footer matching, to deal with structured files that may
    contain embedded files of the same type.  Applicable only to
    FORWARD / NEXT patterns.
-h  Print this help message and exit.
-i  Read names of disk images from specified file.  Note that minimal parsing of
    the pathnames is performed and they should be formatted to be compliant C
    strings; e.g., under Windows, backslashes must be properly quoted, etc.
-n  Don't add extensions to extracted files.
-o  Set output directory for carved files.
-O  Don't organize carved files by type. Default is to organize carved files
    into subdirectories.
-p  Perform image file preview; audit log indicates which files
    would have been carved, but no files are actually carved.  Useful for
    indexing file or data fragment locations or supporting in-place file
-q  Carve only when header is cluster-aligned.
-r  Find only first of overlapping headers/footers [foremost 0.69 compat mode].
-V  Print copyright information and exit.
-v  Verbose mode.
