DESCRIPTION

       The  main  purpose  of  this utility is to recompress and test the zip archives to get the
       smallest possible size.

       For  recompression  the  7‐Zip  (www.7‐zip.com)  Deflate  implementation  is  used.   This
       implementation   generally   gives   5‐10%   more   compression   than  the  zLib  Deflate
       implementation.

       For experimental purpose also the 7‐Zip LZMA algorithm is available with the ‐N option. In
       this case, the generated zips WILL NOT BE USABLE by any other program. To make them usable
       you need to recompress them without the ‐N option. Generally this algorithm  gives  10‐20%
       more compression than the 7‐Zip Deflate implementation.

OPTIONS

       ‐a, ‐‐add ARCHIVE FILES...
              Create  the  specified  archive with the specified files. You must specify only one
              archive.

       ‐x, ‐‐extract ARCHIVE
              Extract all the files on the specified archive. You must specify only one archive.

       ‐l, ‐‐list ARCHIVES...
              List the content of the specified archives.

       ‐z, ‐‐recompress ARCHIVES...
              Recompress the specified archives. If the ‐1, ‐2, ‐3 options  are  specified,  it’s
              used  the  smallest  file  choice  from:  the  previous  compressed  data,  the new
              compression and the uncompressed format. If the ‐0 option is specified the  archive
              is always rewritten without any compression.

       ‐t, ‐‐test ARCHIVES...
              Test the specified archives. The tests may be extended with the ‐p option.

       ‐N, ‐‐not‐zip
              Use the LZMA algorithm when compressing. The generated zips will not be readable by
              any other application!

       ‐p, ‐‐pedantic
              Be pedantic on the zip tests. If this flag is enabled some more extensive tests  on
              the  zip  integrity  are  done.  These  tests  are  generally not done by other zip
              utilities.

       ‐0, ‐‐shrink‐store
              Disable the compression. The file is only stored and not compressed. This option is
              very  useful to expand the archives of .png and .mp3 files. These files are already
              compressed, trying to compress them another time is really  a  waste  of  time  and
              resource.

       ‐1, ‐‐shrink‐fast
              Set the compression level to ˝fast˝.

       ‐2, ‐‐shrink‐normal
              Set the compression level to ˝normal˝. This is the default level of compression.

       ‐3, ‐‐shrink‐extra
              Set the compression level to ˝extra˝.

       ‐4, ‐‐shrink‐insane
              Set the compression level to ˝insane˝.
