var success = false;

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

var zip = new CkZip();

success = zip.OpenZip("my_files.zip");
if (success == false) {
    console.log(zip.LastErrorText);
    return;
}

var unzipDir = "/temp/unzipDir";

// Get the number of files and directories in the .zip
var n = zip.NumEntries;

var entry = new CkZipEntry();

var i = 0;
while (i < n) {

    zip.EntryAt(i,entry);
    if (entry.IsDirectory == false) {
        // (the filename may include a path)
        console.log(entry.FileName);

        // Your application may choose to unzip this entry
        // based on the filename.
        // If the entry should be unzipped, then call Extract(unzipDir)
        success = entry.Extract(unzipDir);
