If you have sensitive files or incriminating files or anything you’d rather not be exposed to eyes other than your own, use the built-in Disk Utility in OS X. It’s free, but not so easy, with plenty of steps to copy files, encrypt files, add a password. Here’s an easier way.
When Invisible Means Invisible
The benefit of using a Mac app to hide files from others is obvious. That’s what makes encryption software so popular these days. Without a password, those encrypted files won’t be visible.
So, they’re invisible, right? Almost. For the lighter side of security there’s the Mac app called Invisible. It hides files and folders quickly, painlessly, and with password protection.
If you can drag and drop files and folders, and have a password, then you can use Invisible to keep sensitive files hidden from view.
Once the files have been moved to Invisible and you’ve added a password, they’re hidden. That means, almost invisible. Almost. The files are still there, but to view them you’ll need to enter the password.
Invisible is for casual security, not ultimate security, despite the password. All it does is change the visibility flag on the files. The password changes the visibility to visible again, and the files are viewable. What would be nice is a simple way to wrap the files into a container of sorts, encrypt, then add a password so the files can be stored (or, shared). One app that does just that is called Encrypto. It works on Mac and Windows and it’s free.
