Reading a directory on schedule

[Mikael Andersson Wigander]

HI, sorry for a stupid question but I can't get this to work properly…

I thought by adding a scheduler to a file component it will only poll for files 
on schedule but apparently it executes as soon a file is present…

What am I doing wrong here or have I understood this completely wrong?

@Component
public class ReadFilesOnSchedule extends RouteBuilder {
@Override
public void configure() throws Exception {
from(
"file:test/" +
"?sortBy=file:modified" +
"&readLock=fileLock" +
"&scheduler=quartz2" +
"&scheduler.cron=0/3+*+*+?+*+MON-FRI" +
"&scheduler.triggerId=testId" +
"&scheduler.triggerGroup=TEST")
.id("TESTSCHEDULER")
.log("Filename: ${header.CamelFileName}")
.end();
}
}
