do {
    let filePath = Bundle.main.url(forResource: "file", withExtension: "zip")!
    let unzipDirectory = try Zip.quickUnzipFile(filePath) // Unzip
    let zipFilePath = try Zip.quickZipFiles([filePath], fileName: "archive") // Zip
}

    }) // Unzip

    let zipFilePath = documentsFolder.appendingPathComponent("archive.zip")
    try Zip.zipFiles([filePath], zipFilePath: zipFilePath, password: "password", progress: { (progress) -> () in
        print(progress)
    }) //Zip

}
