Hi !

I've to write a simply program to create zip file in silverlight and I've problem with saving my zip file on local disk. Every time I try to do that I receive error "File operation not permitted. Access to path ("path...") is denied" Is there any way to do that without IsolatedStorageFile ? I try to save zip file in my project folder but it didn't help.

You can access the local file system from a regular in-browser Silverlight app, but only through a "Save as" dialog (see SaveFileDialog Class[^]), and this dialog must be user-initiated (like on a button click handler).

For example:

private void saveButton_Click(object sender, RoutedEventArgs e)
{
    SaveFileDialog sfdlg = new SaveFileDialog();
    sfdlg.Filter = "ZIP Files (*.zip)|*.zip";
    if (true == sfdlg.ShowDialog())
    {
        using (Stream fs = sfdlg.OpenFile())
        {
            // use the stream "fs"
        }
    }
}

You cannot access the client side file system from a Silverlight app unless it's configured to run out-of-browser. Even then, you can only access a special folder created on the client system. It's a security thing.
