regex pattern that takes only directory without file name

private void txtDownloadRoot_Validating(object sender, CancelEventArgs e)
        {
            Regex driveCheck = new Regex(@"([a-zA-Z]:\\[^/:\*;\/\:\?<>\|]+)|(\\{2}[^/:\*;\/\:\?<>\|]+)");
            if (!driveCheck.IsMatch(txtDownloadRoot.Text))
            {
                e.Cancel = true;
                txtDownloadRoot.Focus();
                errorProvider1.SetError(txtDownloadRoot, "invalid path...!!!");
            }
            else
            {
                errorProvider1.SetError(this.txtDownloadRoot, String.Empty);
            }

Why do you want to do this with a regex?

GetFileName seems more appropriate to get the file name, after that it's easy to get the directory name.
