How do I make my folders inaccessible by other administrator accounts on Windows 8?

I want to make my folders private, so that they can only be accessed after logging in with my own account, but be inaccessible by other local accounts, even the administrator accounts.

I have a PC with windows 8 Professional.

I know I can set the security options for a folder and deny full control access for any other account already created. But since there are other Administrator accounts, new accounts can be created from there and then my folder will be accessible from there.

And if I deny access for ALL administrator group, then even I myself wont have access to my folder!

What is the solution?

within the windows ecosystem, there is NEVER a way to keep an admin out of your files, especially if they have physical access to the machine. Trying to keep admins out is a good way to lose access to your own files.

instead look at an external encryption solution like Truecrypt or even PGP/GPG. MS EFS goes a long way, but if another user can export your cert, its completely worthless for your usecase.

You can make it slightly more difficult for them by changing Owner of the file to be you and removing (not deny, but remove) the Administrator's permission in the advanced file permissions options, but this will only prevent them from being able to access the file without taking ownership. As a system admin, they will be able to take ownership of the file and then change the permissions to give themselves permissions again.

It is worth noting that this will also break the inheritance of permissions on that directory tree at the point that you do your advanced edit.
