When a user puts in a CD and autoruns, I want to "browse" the CD but I want to do some extra processing of the disk contents. If I wanted to replace the ListView in windows explorer with one of my own, how would I start? What terms should I search for to find out how to do this. I want to get the treeview part that explorer provides, and all the shell interaction, I just want to hide the extra extension on the end of the file names (.pgp) and show the icons for the files as if they weren't encrypted.
