You can use the InitialDirectory property : http://msdn.microsoft.com/fr-fr/library/system.windows.forms.filedialog.initialdirectory.aspx

OpenFileDialog openFileDialog1 = new OpenFileDialog();
openFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*";
openFileDialog1.InitialDirectory = previousPath;
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
    previousPath = Path.GetDirectoryName(openFileDialog1.FileName);
    acc_path = openFileDialog1.FileName;
    Settings.Default.acc_path = acc_path;

    foreach (string s in File.ReadAllLines(openFileDialog1.FileName))
    {
        accs.Enqueue(s);
    }
    label2.Text = accs.Count.ToString();
}
