    First the two files are compared byte-by-byte. If a difference is found the corresponding entries of both ZIP files are compared. Thus if same contents is packed differently the two archives may still be the same.
    
    Two archives are considered the same if
    1. they contain same number of entries,
    2. for each entry in the first archive there exists an entry with the same in the second archive
    3. for each entry in the first archive and the entry with the same name in the second archive
      
      both are either directories or files,
      
      both have the same size,
      
      both have the same CRC,
