DESCRIPTION

       The sozip utility can be used to:

       • create a SOZip (Seek-Optimized ZIP) file

       • append files to an existing ZIP/SOZip file

       • list the contents of a ZIP/SOZip file

       • validate a SOZip file

       • convert an existing Zip file in a SOZip optimized one

       --quiet
              Quiet mode. No progress message is emitted on the standard output.

       --verbose
              Verbose mode.

       -g

       --grow Grow  an  existing zip file with the content of the specified filename(s).  This is
              the default mode of the  utility.  This  switch  is  here  for  compatibility  with
              Info-ZIP zip utility

       --overwrite
              Overwrite the target zip file if it already exists.

       -l

       --list List  the  files  contained  in the zip file in an output similar to Info-ZIP unzip
              utility, but with the  addition  of  a  column  indicating  whether  each  file  is
              seek-optimized.

       --validate
              Validates  a SOZip file. Baseline ZIP validation is done in a light way, limited to
              being able to browse through ZIP records with the InfoZIP-based ZIP reader used  by
              GDAL.  But  validation  of the SOZip-specific aspects is done in a more thoroughful
              way.

       -j

       --junk-paths
              Store just the name of a saved file (junk the path), and  do  not  store  directory
              names.  By  default,  sozip  will  store  the  full  path  (relative to the current
              directory).

       --optimize-from=<input.zip>
              Re-process {input.zip} to generate a SOZip-optimized .zip. Options  --enable-sozip,
              --sozip-chunk-size and --sozip-min-file-size may be used in that mode.

       --enable-sozip=auto/yes/no
              In  auto  mode,  a  file  is  seek-optimized only if its size is above the value of
              --sozip-chunk-size.  In yes mode, all input files will be  seek-optimized.   In  no
              mode, no input files will be seek-optimized.

       --sozip-chunk-size
              Chunk  size  for  a  seek-optimized  file.  Defaults  to  32768 bytes. The value is
              specified in bytes, or K and M suffix can be respectively used to specify  a  value
              in kilo-bytes or mega-bytes.

       --sozip-min-file-size
              Minimum   file   size   to   decide   if   a  file  should  be  seek-optimized,  in
              --enable-sozip=auto mode. Defaults to 1 MB byte. The value is specified  in  bytes,
              or  K,  M  or  G  suffix can be respectively used to specify a value in kilo-bytes,
              mega-bytes or giga-bytes.

       --content-type=<value>
              Store the Content-Type for the file being added as a key-value pair  in  the  extra
              field extension 'KV' (0x564b) dedicated to storing key-value pair metadata

       <zip_filename>
              Filename of the zip file to create/append to/list.

       <filename>
              Filename of the file to add.

MULTITHREADING

       The  GDAL_NUM_THREADS  configuration  option  can be set to ALL_CPUS or a integer value to
       specify the number of threads to use for SOZip-compressed files. Defaults to ALL_CPUS.

C API

       Functionality of this utility can be done from C with CPLAddFileInZip() or VSICopyFile().

EXAMPLES

       Create a, potentially seek-optimized, ZIP file with the content of my.gpkg:

          sozip my.gpkg.zip my.gpkg

       Create a, potentially seek-optimized, ZIP file from the content of a source directory:

          sozip -r my.gpkg.zip source_dir/

       Create a, potentially seek-optimized, ZIP file from an existing ZIP file.

          sozip --convert-from=in.zip out.zip

       List the contents of a ZIP file and display which files are seek-optimized:

          sozip -l my.gpkg.zip

       Validates a SOZip file:

          sozip --validate my.gpkg.zip
