Is there a way to process file by detecting ACK files

I have an application and periodically files are coming in one folder. There is always two files that comes, one is named ACK + Name of the file and is empty, and the other one is just the name of the file (this one is the data file).

I heard from some people that there is a way in Camel to process my file by detecting the ACK.

What I'm current doing is to detect the ACK file and then trigger a process that will get the data file and process it. But with this I can't have working unit test for my code.

But if it's possible I'd prefer to have a route that detect my ACK but trigger the process with the data file.

Is this possible ?

Here is my actual route:

@Component
public class MyRoute extends RouteBuilder {
    public static final String ROUTE_NAME = "myRoute";

    private final Processor myProcessor;

    @Autowired
    public MyRoute(@Qualifier("my.processor") Processor myProcessor) {
        this.myProcessor= myProcessor;
    }

    @Override
    public void configure() throws Exception {

        from("file://{{data.input.dir}}?moveFailed=errors&delete=true&include=ACK.*").routeId(ROUTE_NAME)
                .choice()
                    .when(header("CamelFileName").startsWith("ACK"))
                    .process(myProcessor)
                .end();
    }
}

EDIT: Found the solution using the doneFileName option

As you found out by yourself, Camel can handle this automatically with the doneFileName option.

You don't have to process the ACK file at all.

But as a consequence: if an ACK file is missing, the data file is not processed since Camel treats datafiles without done-file as still in process of transfer/writing.
