Question

How can I manage to add a context menu for windows recycle bin? And how could I eventually access the files within? I know Recycle bin is a virtual folder and that it has a tree-like structure, do I have to go all the way to access the files within?

Look at the following Registry keys:

HKEY_CLASSES_ROOT\CLSID\{645FF040-5081-101B-9F08-00AA002F954E}\Shell
HKEY_CLASSES_ROOT\CLSID\{645FF040-5081-101B-9F08-00AA002F954E}\ShellEx

For what you are attempting, you will likely have to write a Context Menu Shell Extension and register it in the ShellEx key.
