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

var entry = new CkZipEntry();

success = zip.EntryOf("hamlet.xml",entry);
if (success == false) {
    console.log(zip.LastErrorText);
    return;
}

entry.FileName = "hamlet2.xml";

success = zip.EntryOf("helloWorld.pl",entry);
if (success == false) {
    console.log(zip.LastErrorText);
    return;
}

entry.FileName = "hw.pl";

// Now unzip to the "test" subdirectory, under our current
// working directory:
var numFilesUnzipped = zip.Unzip("test");
if (numFilesUnzipped < 0) {
    console.log(zip.LastErrorText);
    return;
}

// The filenames within the .zip are unchanged, but it unzipped
// test/hw.pl and test/hamlet2.xm
