I want to have my VB.NET program secure folder(s) which all contain a handful of different files so the files within cannot be edited unless the program "unlocks" the folder in Windows. Is this possible? I do not want the folder/files hidden just essentially in some Read-Only state or something or fake out windows into thinking they are already open. The goal is if someone opens the files without the program "unlocking" them, they cannot edit/save changes.

The best solution to achieve this functionality is to create a Kernel Minifilter file system driver that prevents other apps from writing or even reading files specified by your program, however, driver development needs extensive knowledge of the system Kernel.
