Problem in FileSystemWatcher class

Question

Hi all,

we are developing a service which will keep watch on change in folder using

FileSystemWatcher class which is in .net

All events are raising perfect.

Problem comes when we copy a folder(already exist in the path where we have kept watch) to the path where we have kept watch ,then no event is raised. But want that Changed event should be raised.

How to do this ?

Thanks
