Access to the path 'c:\$Recycle.Bin\S-1-5-18' is denied

Question

I have this code to copy all files from source-directory, F:\, to destination-directory.

public void Copy(string sourceDir, string targetDir)
{
  //Exception occurs at this line.
    string[] files = System.IO.Directory.GetFiles(sourceDir, "*.jpg", 
                                             SearchOption.AllDirectories);

    foreach (string srcPath in files)
    {
       File.Copy(srcPath, srcPath.Replace(sourceDir, targetDir), true);
    }
}

and getting an exception.

If I omit SearchOption.AllDirectories and it works but only copies files from F:\

Use following function instead of System.IO.Directory.GetFiles:

IEnumerable<String> GetAllFiles(string path, string searchPattern)
    {
        return System.IO.Directory.EnumerateFiles(path, searchPattern).Union(
            System.IO.Directory.EnumerateDirectories(path).SelectMany(d =>
            {
                try
                {
                    return GetAllFiles(d,searchPattern);
                }
                catch (UnauthorizedAccessException e)
                {
                    return Enumerable.Empty<String>();
                }
            }));
    }
