Runtime.getRuntime().exec(cmdArray) is not properly moving all files

I am running the following code, but it always moves exactly 6 files, no matter what files I put into the incoming directory, leaving the rest of the files behind and indicating that the process is still running.

What could be a possible reason for this?

package com.hsc.underwriting.test;
 
import org.junit.Test;
 
public class IOTest {
	@Test
	public final void testAutoMove() {
		try {
			String[] cmdArray = new String[5];
			cmdArray[0] = "cmd.exe";
			cmdArray[1] = "/C";
			cmdArray[2] = "move";
			cmdArray[3] = "incoming\\**";
			cmdArray[4] = "outgoing\\";
 
			Process autoMoveProcess = Runtime.getRuntime().exec(cmdArray);
			//Thread.sleep(10000);
			autoMoveProcess.waitFor();
			autoMoveProcess.destroy();
		} catch (Exception e) {
			// TODO: handle exception
		}
	}
 
}
