Open Folder Prevention

[howester77]

Is there anyway to check if the user is trying to open a folder and prevent the user from opening it? for example, double click C: drive, and trying to enter C:/Downloads except it wont let you open C:/Downloads?

exactly. Except, I don't want to pay money for it, so im considering creating my own using folderwatch and an encyrption algorithm I have already created. I just need to know how to prevent the folder from being opened.
