Unzip a .zip Archive

Demonstrates how to open a .zip archive and unzip. The Unzip method extracts the files and directories from a .zip archive and recreates the directory tree rooted at the directory path passed to Unzip.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

JavaScript

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 !== true) {
    console.log(zip.LastErrorText);
    return;
}

var unzipCount;

// Returns the number of files and directories unzipped.
// Unzips to /my_files, re-creating the directory tree
// from the .zip.
unzipCount = zip.Unzip("/my_files");
if (unzipCount < 0) {
    console.log(zip.LastErrorText);
}
else {
    console.log("Success!");
}
