    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    i := 0

    // entry is a ZipEntry

    for i < numEntries {
        entry := zip.GetEntryByIndex(i)
        // 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.IsDirectory() {
            fmt.Println(i, ": ", entry.FileName(), " (directory)")
        } else {

        entry.DisposeZipEntry()
        i = i + 1

    // Sample output:

    // 0: aaa/ (directory)
