Integrating with Explorer.exe

How would I go about integrating my app with every Folder that is opened? I'm trying to add some advanced features that would make finding files and such easier.

Would I have to create a COM of some kind and stick it somewhere? How would that work.

I attached a screen shot of what I'm trying to achive. For my example I took a screenie of popup cop that is integrated into the shell somehow.

Thanks for all the help!

What do you mean "integrate with a folder"??

- You can add your app to the SendTo right-click pop-up menu (very easily) in Windows Explorer.
- You can add your app to the right-click pop-up menu in Windows Explorer.
- You can asociate a file extension with your app, so double clicking on those files launches your app.
- You can list what is in a folder from within your application, and display the results how you want.

All the above without a COM module in sight. Just simple VB.
