    # 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.
    if (entry.get_IsDirectory())
        print i.to_s() + ": " + entry.fileName() + " (directory)" + "\n";
    else
        print i.to_s() + ": " + entry.fileName() + "\n";
    end

    i = i + 1
end

# Sample output:

# 0: aaa/ (directory)

# 2: bbb/ (directory)
# 3: bbb/base64Cert.txt
# 4: bbb/sub1/ (directory)
