You could delete all files that are older than a certain timespan. e.g.

private void CleanTempFiles(string dir, int ageInMinutes)
{
    string[] files = Directory.GetFiles(dir);

    foreach (string file in files)
    {
        var time = File.GetCreationTime(file);

        if (time.AddMinutes(ageInMinutes) < DateTime.Now)
        {
            File.Delete(file);
        }
    }
}

Then call it with something like:

CleanTempFiles(root, 60); // Delete all files older than 1 hour
