On macOS, the folders are not encrypted directly, but you can set a password to protect it. This is an effective way of protecting folders and files contained therein. You can set the folder password on macOS using the built-in Disk Utility or the third-party Encrypto tool.
How to set a password to protect the folder using Disk Utility
You can protect the content within a folder by copying them to a password-protected disk image. This will create a new dmg file with password protection. The root directory will not be affected and you can delete it when you finish copying the content to disk image.
Step 1 . Open Disk Utility from Spotlight or ' / Applications / Utilities / Disk Utility.app '.
Step 2 . Select File> New Image> New Image from Folder . from the menu bar.
Step 3 . Select the folder you want to password protect from the file explorer window that appears.
Step 4 . In the Encryption menu, select 128-bit AES Encryption or 256-bit AES encryption . The second option is safer but takes more time to encrypt and decode. Both of these formats provide a good level of protection for your data, so here we will choose 128-bit AES.
Step 5 . Enter the password when prompted. This is the password you will use to unlock the disk image, unlike your Mac password. To ensure data safety, you should set a hard-to-guess password.
Step 6 . In the Image Format menu, select read / write to add the file to the image if you want. Or not if you just need to see the files on the disk image without updating or adding new files.
Step 7 . Click Save to create the encrypted disk image and it will notify you when the creation process is complete.
Step 8 . Unless in the previous step you have another saved location, otherwise the disk image will appear next to the folder you have chosen to set a password protection.
The DMG file is not the same as your directory, but it is a copy of the contents of the directory in the disk image format. This disk image is password protected, requires entering a password to mount and read the contents.
When opening the disk image, you need to enter the password to access the image and see all the files of the folder. After checking the image, you can delete the unencrypted folder.
