Unzip all Files to a Single Directory (Ignoring Subdirectories in Zip)

See more Zip Examples

Demonstrates how to unzip all files into a single directory, ignoring the internal directory structure of the files in the .zip.
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 assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

var outDir = "c:/temp/testUnzipDir";

// Make sure our output directory exists.
var fac = new CkFileAccess();
success = fac.DirEnsureExists(outDir);
if (success == false) {
    console.log(fac.LastErrorText);
    return;
}

var zip = new CkZip();

// In this example, the xml_files.zip contains some files in the subdirectories "dir1" and also "dir2/dir3".

// a1.xml
// b1.xml
// c1.xml
// dir1/a2.xml
// dir1/c2.xml
// dir2/dir3/c3.xml

success = zip.OpenZip("qa_data/zips/xml_files.zip");
if (success == false) {
    console.log(zip.LastErrorText);
    return;
}

// Unzip all files into the directory c:/temp/testUnzipDir
var numUnzipped = zip.UnzipInto(outDir);
if (numUnzipped < 0) {
    console.log(zip.LastErrorText);
    return;
}

console.log("Num unzipped = " + numUnzipped);

// After unzipping via UnzipInto, we have this:

// c:\temp\testUnzipDir\a1.xml
// c:\temp\testUnzipDir\b1.xml
// c:\temp\testUnzipDir\c1.xml
// c:\temp\testUnzipDir\a2.xml
// c:\temp\testUnzipDir\c2.xml
// c:\temp\testUnzipDir\c3.xml

zip.CloseZip();

console.log("Success.");
