I'm using BackgroundWorker

Answer 1

Use the ReportProgress method in combination with the ProgressChanged event. This type of scenario is exactly what they are intended for.

Answer 2

You can use ReportProgress method of background worker.

Answer 3

You would need to implement a foreground worker and invoke it from the background worker.

Ideally, you would be passing a list of any newly found files to the foreground worker.
