TRANSCRIPT:

In this episode, How To Create an Auto-Expanding Password Protected Folder in OS X El Capitan.

Phew, what a mouth full.

This episode is an update from a previous episode that was done using Disk Utility for OS X Yosemite.

Using the new Disk Utility in El Capitan, creating and resizing an encrypted Password Protected Auto-Expanding Folder, also know as a Sparse Bundle Disk Image, is a relatively easy process.

For additional information with regards to a Sparse Bundle Disk Image, watch the episode titled: “How to Create a Password Protected Auto-Expanding Folder”, shown here.

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 Blank Image…

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

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

Then, a Name for the Folder inside the image file…I’ll call mine…Top Secret.

Next the Size that you want the Folder to be…I’ll choose 100 MB for now…this can be resized if more space is needed, as will be shown in just a moment.

Leave the Format as OS X Extended (Journaled)

For Encryption, choose the recommended 128-bit.

After choosing 128-bit, 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 the Partitions…Leave at default of Single partition - GUID Partition Map

Finally; for Image Format, select sparse bundle disk image as shown.

Now, after pressing the Save button, the Secure sparse bundle image file named Black Book with the sparsebundle extension and the mounted Folder named Top Secrete will be created on the Desktop.

I’ll now just copy some items to the mounted Top Secret Folder.

If you find that you need more space, simply resize the sparse bundle image file as described here.

First, make sure to eject the mounted Top Secret Folder.

Next, open Disk Utility and from the menu bar, click on Images, then select Resize…

From the drop down dialog window, click once on the Black Book spare bundle image file, then click the Open button shown here.

Enter the password created earlier and after clicking on the OK button, you’ll be presented with the New Size dialog panel, where you basically choose a size that you want for the image file.

I’ll just increase it to 500 MB.

And that’s all there is to it,  a secure password protected Folder that can be resized  when needed.
