c# determine which files are incoming/outgoing

I had a project to convert existing folders files into different category folder!  Attached is the sample files (see attachment).  I wanted to identify which file is Incoming and which is Outgoing.  The naming on the files can be identify from the name "Incoming" and "Outgoing".  Now how can I code it in c# to identify that?  I had like thousands of files to convert so it would make senses to write code to do the job!  

The foldername is 2012 which contains all the files in it.

You just need to test the text of each file's name for whether it contains the text "Incoming" or "Outgoing."

Here's a way to do this:

public enum IODirection
{
      Unknown,
      Incoming,
      Outgoing
}

public static IODirection WhichDirection(string filename)
{
      IODirection result = IODirection.Unknown;

      if (filename.Contains("Incoming"))
            result = IODirection.Incoming;
      else if (filename.Contains("Outgoing"))
            result = IODirection.Outgoing;

      return result;
}

public void Example()
{
      string folderPath = "C:\\ExampleFolder";
      foreach (string filename in System.IO.Directory.GetFiles(folderPath))
      {
            if (WhichDirection(filename) == IODirection.Incoming)
            {
                  // ...
            }
            else if (WhichDirection(filename) == IODirection.Outgoing)
            {
                  // ...
            }
      }
}
