I'm assuming these exist already but I wrote my own. It cleans out the bin, obj, SVN directories so you don't have to. It also removes the resharper directory since no one wants that. If you don't have resharper, i suggest getting it.

XML Code

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <appSettings>
    <add key="folderPatterns" value=".svn|_Resharper*|bin|obj"/>
    <add key="filePatterns" value="*.resharper|*.resharper.user|*.suo"/>
  </appSettings>
</configuration>

Application

private void button1_Click(object sender, EventArgs e)

    if (folderBrowser.ShowDialog() == DialogResult.OK &&
        folderBrowserBackup.ShowDialog() == DialogResult.OK)
    {
        DirectoryInfo di = new DirectoryInfo(folderBrowser.SelectedPath);
        DirectoryInfo backupDir = new DirectoryInfo(
            Path.Combine(folderBrowserBackup.SelectedPath, di.Name));

        textBox1.Text = string.Empty;
        CopyAll(di, backupDir,
            RegexFilePattern(ConfigurationManager.AppSettings[
