Determine if a folder is clicked/selected in windows Explorer

[gibra]

I wish to be able to detect if a 'secured' folder is selected/clicked so that I can ask for a password to 'open' the folder, can anyone give me a hint on where or what to look for?

You can implement a Shell notify (subclassing is need), see this project:
