TRANSCRIPT:

In this episode: Password Protect an Existing Folder in OS X El Capitan.

Using the all new Disk Utility in El Capitan, encrypting and password protecting all files in a Folder is a relatively easy process.

Demo time.

Sooooooo…Let’s Get Started.

IMPORTANT NOTE: Make sure you have a backup of your internal hard drive before using Disk Utility…Period.

Continuing on.

Launch Disk Utility and from the Disk Utility menu bar, click on File and select New Image and then click Image from Folder…

In this example, all the files in the folder named Top Secret and located on the Desktop as shown, will be encrypted.

Therefore, click the Top Secret Folder, then click the Open button shown here.

Now enter a name and location where you want the encrypted file to be created.

I’ll choose Black Book for the name and create it on the Desktop.

Next, after choosing 128-bit for the level of encryption, a pop-up window will appear to choose a password.

Enter one manually or click the key icon to have one selected for you.

I’ll just enter one manually and then click on the Choose button to continue.

For Image Format, choose read/write.

Next, click the Save button for the encryption process to begin.

Finally, when the encryption process has finished, the file named Black Book with the dmg extension will be created on the Desktop, click the Done button to finish.

You can now Delete the original Top Secret Folder as you have it encrypted in the Black Book dmg file.

Now, whenever you double click on the Black Book dot dmg file, you will be asked to enter a Password, do so and the password protected folder Top Secret will be mounted on the Desktop.

Just double click on the mounted disk to view all the files.

Eject the mounted disk by either pressing ctrl-click or right click the mouse button and choose Eject or simply drag to the Trash as shown.

I’ll just quickly remove the file extension and change the icon in this quick time-lapse.

And that’s all there is to it.
