List Files/Directories in Zip by Index

Demonstrates how to iterate over the files and directories in a zip archive by index. C++

#include <CkZip.h>

void ChilkatSample(void)
    {
    bool success = false;

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

    CkZip zip;

    int i = 0;
    while (i < numEntries) {
        zip.EntryAt(i,entry);
        // 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()) {
            std::cout << i << ": " << entry.fileName() << " (directory)" << "\r\n";

        }

    // Sample output:

    // 0: aaa/ (directory)
    // 1: aaa/pigs.json
    // 2: bbb/ (directory)
    // 3: bbb/base64Cert.txt
    // 4: bbb/sub1/ (directory)
