Is it possible to decide whether to replace files or skip files that already exist when unzipping

Hello,

I'm working on some scripts to handle unzipping .zip files from within TestComplete. I have a working script that unzips, but I'm just trying to see if there is a way to decide whether to "replace" or "skip".

This is my code to UnZip:

function UnzipFileToDirectory(zipFile, destinationDirectory){

    if(zipFile == undefined || aqString["GetLength"](zipFile) < 1){
        Log["Error"]("There was no zip file provided in the method parameters. Please provide one.");
        return
    }

    //declare variables needed to unzip
    var fso = Sys["OleObject"]("Scripting.FileSystemObject");
    var objShell = Sys["OleObject"]("Shell.Application");

    if(!fso["FolderExists"](destinationDirectory)){
        fso["CreateFolder"](destinationDirectory)
    }

    //Copy the files in the Zip and past them in the destination directory
    var filesInZip = objShell["NameSpace"](zipFile).Items();
    objShell["NameSpace"](destinationDirectory).CopyHere(filesInZip);

}

Currently this code works to extract Zip files, but if there is already a file that exists with the same name as a file in the .zip file, I'll get presented with this window:

Unfortunately, it doesn't look like I can simply click on the buttons as I would expect, because it seem that while that message box is present, TestComplete is still  processing the line below.

Any help would be appreciated.
