- Again, do not lose the password set or you will not be able to get access to the contents of the encrypted disk image. This should not be considered a replacement for setting a general password for a Mac, and it’s always a good idea to lock down the screen when you’re away from the computer.
- Feb 16, 2012 I have an encrypted disk image on my Mac. I would like one of my Outlook inbox folders to reside in the encrypted disk image, so the emails can not be accessed without using the encryption password. I tried dragging the folder icon into my encrypted disk image, but this didn't cut the mustard.
This also applies to transferring the encrypted folder image to another Mac. With a readable and writable encrypted disk image, you can treat it as a normal folder and copy, delete, or move files from the image. Anything brought into the image while mounted will become encrypted automatically under the same protective layer with the same password.

Create a blank disk image for storage
You can create an empty disk image, add data to it, then use it to create disks, CDs, or DVDs.
- In the Disk Utility app on your Mac, choose File > New Image > Blank Image.
- Enter a filename for the disk image, add tags if necessary, then choose where to save it.This is the name that appears in the Finder, where you save the disk image file before opening it.
- In the Name field, enter the name for the disk image.This is the name that appears on your desktop and in the Finder sidebar, after you open the disk image.
- In the Size field, enter a size for the disk image.
- Click the Format pop-up menu, then choose the format for the disk:
- If the disk image will be used with a Mac that has a solid state drive (SSD) and uses macOS 10.13 or later, choose APFS or APFS (Case-sensitive).
- If the disk image will be used with a Mac with macOS 10.12 or earlier, choose Mac OS Extended (Journaled) or Mac OS Extended (Case-sensitive, Journaled).
- If the disk image will be used with a Mac or Windows computer and is 32 GB or less, choose MS-DOS (FAT); if it’s over 32 GB, choose ExFAT.

Create a disk image from a disk or connected device
You can create a disk image that includes the data and free space on a physical disk or connected device, such as a USB device. For example, if a USB device or volume is 80 GB with 10 GB of data, the disk image will be 80 GB in size and include data and free space. You can then restore that disk image to another volume.
- In the Disk Utility app on your Mac, select a disk, volume, or connected device in the sidebar.
- Choose File > New Image, then choose “Image from [device name].”
- Enter a filename for the disk image, add tags if necessary, then choose where to save it.This is the name that appears in the Finder, where you save the disk image file before opening it.
- Click the Format pop-up menu, then choose an option:
- Read-only: The disk image can’t be written to, and is quicker to create and open.
- Compressed: Compresses data, so the disk image is smaller than the original data. The disk image is read-only.
- Read/write: Allows you to add files to the disk image after it’s created.
- DVD/CD master: Can be used with third-party apps. It includes a copy of all sectors of the disk image, whether they’re used or not. When you use a master disk image to create other DVDs or CDs, all data is copied exactly.
- To encrypt the disk image, click the Encryption pop-up menu, then choose an encryption option.
- Click Save, then click Done.Disk Utility creates the disk image file where you saved it in the Finder and mounts its disk icon on your desktop and in the Finder sidebar.
Important: Don’t create a disk image of a disk that you believe to be failing or that contains corrupted information. The disk image may not serve as a reliable backup.

Security enthusiasts have likely noticed that folders can’t be directly password protected in macOS. However, you can still protect your data by placing the folders and files in password-protected containers. This has the effect of protecting your folder and the files it contains with a password. You can password protect folders in macOS using the built-in Disk Utility application or a third-party tool called Encrypto.
Using Disk Utility
You can password-protect the contents of a folder by copying them to a password-protected disk image. This will create a new dmg file, which will be password-protected. The original folder will remain untouched and can be deleted once the contents of the disk image are confirmed.
1. Open Disk Utility from Spotlight or /Applications/Utilities/Disk Utility.app.
2. Choose “File > New Image > New Image from Folder…” from the menu bar.
3. Select the folder you want to password-protect from the pop-up file browser window.
4. In the “Encryption” menu, choose “128-bit AES Encryption” or “256-bit AES encryption.” The second choice is nominally more secure, but takes longer to encrypt and decrypt. Both formats are sufficiently secure for protecting your data, so the faster 128-bit AES is typically recommended.
5. Enter a password when prompted. This is the password you will enter to unlock the disk image. It should not be the same as your Mac password. Make sure it is sufficiently difficult to guess.
6. In the “Image Format” menu, choose “read/write” to allow you to add files to the image. Otherwise, you will only be able to view the files on the image without updating them or adding new files to the image.
7. Click “Save” to create the encrypted disk image. This will start a short process in Disk Utility, which will notify you when it is finished creating the disk image from your folder.
8. Unless you selected a different save location in the previous steps., the disk image will appear next to the folder you selected.
This DMG file is not the same as your folder, but it is a copy of the folder’s contents in a disk image format. That disk image is protected by a password, requiring a password before it can be mounted and read. The original folder has been untouched and is not encrypted.
Open the disk image and enter your password to confirm you can access the image and that it contains all of the folder’s files. Once you’re sure everything worked smoothly, delete the unencrypted folder. This will leave only the encrypted DMG behind.
Using Encrypto
Encrypto is a third-party encryption tool available in the Mac App Store. It provides greater ease of use in encryption and decryption, based on a simple drag-and-drop procedure.
1. Install Encrypto from the Mac App Store.
2. Open Encrypto from the Applications folder.
3. Drag the folder you want to encrypt on to Encrypto’s window.
4. Enter the password you want to protect the folder with. You can also provide an optional hint if you’re afraid of forgetting the password credentials.
5. After you’ve typed in a sufficiently complex password, click “Encrypt” to encrypt the folder in an Encrypto archive.
6. When the encryption is finished, drag the resulting Encrypto archive to a safe location. You can also choose “Share File > Save As…” to save the Encrypto archive to another location.
7. To open the file, double-click the Encrypto archive. Enter your password and click “Decrypt” to unlock the folder.
Then drag the decrypted folder to a save location.
Conclusion
The Disk Utility method of password-protecting a folder will work on any Mac, but it’s slightly clunky. Encrypto is much easier to use but creates proprietary Encrypto archives that might not be future proof. Choose your method depending on your needs and security concerns.
