Create a new user for him on the Windows OS and don't give him the admin status. Transfer all your files to your user's (admin) My Documents folder or other user-related folders. Make sure that you change the settings so that user's files are private and not shared. As long as he doesn't have access to your username or knows how to bypass it (which isn't hard), he shouldn't be able to open them.

Another way would be to zip the files and put a password on them, but that may take a while with the amount of collection you're claiming to have.

Easy way would be to hide them in a secret folder that's buried in an inconspicuous place. You have to hide the folder itself (from properties), then make it so that hidden folders cannot be seen. But, if he knows how to make it so that it's not hidden and/or does a search, he can find the files.


Keep in mind that he can always go online for porn. So, you should also change your internet settings and put a password on it (most browsers have this, so it's not hard). Again, this is easy to bypass also, but if he's not deleting his tracks, then he may not know half the easy ways to go about them.
