How To Hide and Unhide a Folder

Yea that is how I hide folders on my externals, put my files in a folder, set it to hidden, make sure do not show hidden files and folders is checked then the folder well disappear before your eyes. However if you say this method literally removes its trace even from the search function even with search hidden files. Then I will be using this one, as my private folders and files can still be searched for.
