Question

Ok so I have an OpenFileDialog and I want to set the initial directory to the users ‘Download’ folder. This is an internal application and, therefore, I am sure that the user will be using Windows 7.

var ofd = new OpenFileDialog();

//This doesn't work
ofd.InitialDirectory =
    Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Personal), "Downloads");

//This doesn't work either
ofd.InitialDirectory = @"%USERPROFILE%\Downloads";

ofd.Filter = "Zip Files|*.zip";

ofd.ShowDialog();

txtFooBar.Text = ofd.FileName;

I have tried the above so far and neither work. No Exception is thrown, it just doesn’t set the initial directory to the downloads folder.

Where am I going wrong?

Thanks
