How to track the last folder selected by the user?

I thought using application settings would do the trick, but I won’t get it to work. This is what I have:

private void btnBrowse_Click(object sender, EventArgs e)
        {
            if (fbFolderBrowser.ShowDialog() == DialogResult.OK)
            {
                // I want to open the last folder selected by the user here.
            }

When the user clicks on this button, I want to open the browse window to the last folder that he accessed and save it. The next time he presses the button, he automatically selects this folder.

I was thinking maybe I can use custom variables where I can change at runtime, but I can't get it to work. Can someone give me a hand?

There are two places where you can find the last folder available to the user:

  • Recent Files and Folders: It can be found here: C:\Documents and Settings\USER\Recent
  • Registry: in the registry see here: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\ComDlg32\OpenSaveMRU

, :

public static string GetLastOpenSaveFile(string extention)
{
    RegistryKey regKey = Registry.CurrentUser;
    string lastUsedFolder = string.Empty;
    regKey = regKey.OpenSubKey("Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\ComDlg32\\OpenSaveMRU");

    if (string.IsNullOrEmpty(extention))
        extention = "html";

    RegistryKey myKey = regKey.OpenSubKey(extention);

    if (myKey == null && regKey.GetSubKeyNames().Length > 0)
        myKey = regKey.OpenSubKey(regKey.GetSubKeyNames()[regKey.GetSubKeyNames().Length - 2]);

    if (myKey != null)
    {
        string[] names = myKey.GetValueNames();
        if (names != null && names.Length > 0)
        {
            lastUsedFolder = (string)myKey.GetValue(names[names.Length - 2]);
        }
    }

    return lastUsedFolder;
}

If I misunderstood the intention of this post, this is by far the easiest way to achieve it. However, if you need to print this last place, check out the others.
