A year ago I was investigating into being secretive and hiding/encrypting data when I came across a program(can’t remember its name). It basically hid any file or folder and it could not be discovered by unsetting the attributes of hidden in windows explorer.
How do you think the program did this? Is there a way to make your own program to do this?
Does this sound like what you were looking for?
