how can i zip my pictures folder

Hi, you can simplify your life and use third-party librarry called DotNetZip

After you download it and your project will be referenced to it , write the following lines of code :

using (var zip = new Ionic.Zip.ZipFile())
{
    zip.AddDirectory("DirectoryOnDisk", "rootInZipFile");
    zip.Save("MyFile.zip");
}
