How to create an encrypted disk image to store your private files on MAC

Well,This tutorial will guide you through using SecureFiles to create a secure, encrypted disk image in OS X. Using that disk image, you can store files that you don’t want other people to be able to access.

There are quite a few ways to create secure disk images in OS X, or a secure partition. However, using SecureFiles is arguably the easiest way.

1. To get started, download SecureFiles and open the .dmg file. Drag the SecureFiles app to your Applications folder to install it.



2. Launch SecureFiles from your Applications folder.



3. Give your secure disk image a name by entering it in the New disk image name: field. Decide how large you want the image to be by selecting a size from the Size: stretches to drop-down menu. You can create custom size disk images (rather than using one of the defaults) by selecting the Preferences option from the top menu. Now, decide if you want to allow Spotlight to index your secure image. I opted not to, but this is one of those “up to you” decisions. Click the small “folder” icon in the bottom left corner of the SecureFiles window to change the default location your image will be saved in, if you don’t like the default. Finally, click the Create button.



4. Now enter a password for your secure disk image. As the window indicates, if you lose this password you won’t be able to access your secure files. So select a password that’s both secure (hard to guess) and easy to remember. You’ll probably want to remove the check from the box labeled Remember password in my keychain, otherwise you won’t be prompted to enter your password each time you open the image to add or access files to/from it, which (with the default keychain settings) negates the entire SecureFiles process.



5. And now your disk image will be created.



6. Once completed, your disk image will be mounted, and you can access it via the Finder. Drag and drop files to it the same way you would any other. Once inside, they’re part of the encrypted disk image. Unmount the disk image when you’re done.



7. Any time in the future when you want to access the secure disk image - to view/extract or add files to it, just locate the .sparseimage file (it will be saved in the location you specified back in step #3) and double-click it.



8. Enter the password you created in step #4.



9. And your encrypted/secure disk image will mount. Again, now you can access the files inside, or add more to it.
