Answer 1

The only method I know of is to try opening it to see if another process still has a hold on it, e.g.:

 private static Boolean FileInUse(FileInfo file)
 {
  Boolean inUse = false;
  try
  {
   using (file.OpenRead()) {}
  }
  catch (Exception exception)
  {
   inUse = true;
  }

  return inUse;
 }

Answer 3

private static Boolean FileInUse(FileInfo file)
        {
                Boolean inUse = false;
                try
                {
                        using (file.Open(FileMode.Open, FileAccess.ReadWrite, FileShare.None)) {}
                }
                catch (Exception exception)
                {
                        inUse = true;
                }

                return inUse;
        }
