   Fileformat:
              PGZF  fellows  standard  GZIP format (rfc1952), and is blocked compressed.  It defines two TAGs in
              each GZIP header, ZS: block size, ZX: random access index.  Program pgzf can decompress .pgzf  and
              .gz files. When decompressing .gz files, pgzf is in fact a buffered gzip reader. Also, .pgzf files
              can be decompressed by program gzip.

       In plan to support random access
