    // Note: In the ZIP file format, it is not required for a ZIP file to contain explicit directory entries. 
    // However, explicit directory entries can be included for convenience and compatibility with certain ZIP file processing tools and software.
    // An explicit directory entry in a ZIP file is an entry that specifically represents a directory, rather than a file. 
    // It usually has a directory name with a trailing slash (/) and zero-length content.
