On Windows, you have Bitlocker. Cross-platform, you also have VeraCrypt (successor to TrueCrypt). But if you want to encrypt afolder on the fly in MacOS, then the quickest and easiest way is to use DiskUtility.

Disk Utility is a function built into the MacOS operatingsystem and can do things such as wiping and formattingmacOS hard-drivesand removable media such as USB sticks. But it can also take a folder on aMacOS and encrypt it using the DMG format.

The DMG Format

Does anyone know of a tool that will supports encrypted.dmg (OSX disk image) files under Windows?

How to open Apple's DMG files in Windows 10. By Roger Fingas Friday, June 07, 2019, 08:45 am PT (11:45 am ET) One of the potentially frustrating things about switching back and forth between Mac.

If the DMG format sounds familiar to you then that’s probablybecause that is also the standard file format for MacOS software installationfiles. DMG files are mountable disk images which compress the files insidethem, much the same way a Zip file compresses Windows files in a folder.

As well as compressing files, DMG can also encrypt them.Here’s how.

Making An Encrypted Folder In Disk Utility

Make a new folder on your computer and put all the files youwant to encrypt into that folder.

Now open Disk Utility which you will find by going toApplications–>Utilities.

Go to the menu at the top and choose File–>NewImage–>Image From Folder.

Now navigate to the location of your folder of secret files,which in my case is on the desktop. Highlight the folder and click “Choose”.

In the box that pops up, confirm the following :

• Thefile name for the encrypted folder.
• Whereyou want it saved.
• Thestandard of encryption (128-bit is generally sufficient).
• Set“Image Format” to “Read/Write”.

When you set the encryption standard, a password box will popup asking you to enter your desired password.

If you already have a desired password, type it in twice andclick “Choose”. However, if you are not sure of your password, the little blackkey icon next to the “Verify” box is a Password Assistant. Click the key toopen it.

Drop the menu down and choose what type of password you want.When you do, a password will auto-fill for you in the boxes provided.

You can also specify how long the password will be and theQuality bar will update in real time.

It’s worth pointing out that if you go for a random passwordoption, you are going to need to copy and paste it somewhere to remember it. Orbetter still, use a password manager. The last thing you need is to belocked out of your own encrypted folder.

When you have the password you want, close the PasswordAssistant and you will be back at this window.

Click “Save” to begin the encryption process. How long itwill take will depend on how large your encrypted folder is going to be.

When the DMG file has been created, the original unencryptedfolder will still be there. It is not deleted by Disk Utility. So you may wantto delete that folder, but as I said just now, make sure you have a copy of thepassword first. Otherwise you will be permanently locked out.

If you go to your newly created encrypted DMG file, anddouble-click on it, it will ask you for your password. Do NOT tick the Keychainoption.

One of the potentially frustrating things about switching back and forth between Mac and Windows PCs can be proprietary formats —a key example being Apple's DMGs (disk images). Here's how to extract content from a DMG in Windows 10.


The best option, whenever possible, is using 7-Zip. You probably already have it if you're a Windows regular, since it's a free and convenient way of extracting the more universal ZIP format.
Once Z-7ip is installed, find the DMG file you want to work with in File Explorer and right-click on it. In this case we're using some of Apple's free system fonts as an example.
Mouse over '7-Zip' in the right-click menu, then select 'Extract Here' or 'Extract files.' That should give a choice of where to send extracted material, though by default the app will create a subfolder in your current File Explorer location. Click 'OK' once you've chosen a place.

There's a good chance you'll have to dive into the new subfolder and run extraction again. With Apple's font DMGs for example, the real meat is buried within an HFS archive, which you'll need 7-Zip for. HFS is a filesystem used exclusively by Macs.

That should be it — you may see a lot of confusing folders and files, but what you want should be buried in there somewhere.

An alternative to 7-Zip is DMG Extractor. Though it's very straightforward we're inclined to recommend using 7-Zip as your first resort, since DMG Extractor has harsh limitations without a paid license. You can't extract more than 5 files from a DMG simultaneously, and it simply won't work with encrypted files or those bigger than 4 gigabytes.

How To Open Encrypted Files

Neither 7-Zip nor DMG Extractor are the ultimate solution, though. There are some DMG files that 7-Zip, nor other alternatives that we've tried will open. For instance, if on the Mac, a end-user license agreement instantly pops up, we've found that most of the time, Windows solutions will choke on these.
