Deark
Deark is a portable command-line utility that can decode certain types
of files, and either convert them to a more-modern or more-readable format,
or extract embedded files from them.
It also has an option (-d) to display detailed information
about a file’s contents and metadata.
It’s free and open source.
Downloads
The download package includes source code, and a Windows 64-bit (x64)
binary, in the “x64” directory. Windows users may need to install
a utility that supports .tar.gz format, such as
7-Zip.
