preventing access/locking a folder?

Hi all,


Need help with this issue. I've been looking online for couple hours for a code that would allow me to prevent access or lock the folder, meaning the folder wouldn't opening by any means (double clicking, command prompt, etc....), but no luck finding such a code. Can anyone help?

I may be wrong, but you may be using the wrong tool if you're asking Java to do this as this is an OS function, and Java was built to be OS-agnostic (as much as reasonably possible).
