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.

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 ctrlclick or right click the mouse button.
