    {
        static void Main(string[] args)

        }

        private static void CopyDirectory(string sourcePath, string targetPath)
        {
            // To copy a folder's contents to a new location: 
            // Create a new target folder, if necessary. 
            if (!System.IO.Directory.Exists(targetPath))
            {
                System.IO.Directory.CreateDirectory(targetPath);
            }

            if (System.IO.Directory.Exists(sourcePath))
            {
                string[] files = System.IO.Directory.GetFiles(sourcePath);
                string fileName = null;
                string destFile = null;
                // Copy the files and overwrite destination files if they already exist. 
                foreach (string s in files)
                {
                    // Use static Path methods to extract only the file name from the path.
                    fileName = System.IO.Path.GetFileName(s);
                    destFile = System.IO.Path.Combine(targetPath, fileName);
                    if (Path.GetExtension(fileName) == ".avi")
                    {
                        System.IO.File.Copy(s, destFile, true);
                        System.IO.File.Delete(s);
                    }

Directory.GetFiles has an overload that could be used to get the list of files in subdirectories 

  string[] files = Directory.GetFiles(sourcePath, "*.*", SearchOption.AllDirectories);

The remainder of your code should work as is, however, if your are interested only in the AVI files then you could put that extension directly in the GetFiles call. In that way you get only AVI files and your code could be simplified removing the if 

string[] files = Directory.GetFiles(sourcePath. "*.AVI", SearchOption.AllDirectories);
string fileName = null;
string destFile = null;
// Copy the files and overwrite destination files if they already exist. 
foreach (string s in files)
{
    // Use static Path methods to extract only the file name from the path.
    fileName = Path.GetFileName(s);
    destFile = Path.Combine(targetPath, fileName);
    File.Copy(s, destFile, true);
    File.Delete(s);
}

I suggest also to add a using System.IO; at the top of your code file to avoid all of that full namespace typing required without the using
