Cloak is an application that provides you with a solution for when it's imperative to hide files and folders within your Mac. You can work with this program whenever you wish to prevent other users from accessing or modifying private documents from your computer.
The app brings you two hiding methods: prefix the file or folder name with a dot or assign an invisible attribute. Once you finish making the necessary adjustments, you can close the application and resume your work; as even if you shut down Cloak, the processed files and folders will remain hidden from prior eyes.
A good thing about working with this program is that you don't need to provide access passwords when hiding or revealing files and folders within your Mac. When using Cloak you can display or hide files and folders with just a click of a button (Show Invisible Items button from the bottom of the main window).
To summarize, Cloak proves to be a smart addition to any user's collection of applications as it offers a very simple way to manage invisible files and folders.
