How to password protect a folder
Posted by: jardster
Date: January 29, 2018 06:47AM
Looking for a little forum help here...

I'm running Sierra on my MBP and need to password protect one folder. Currently the folder has about 10 GB of documents in it, but I am constantly adding documents.

I found that you can create a disk image of the folder using Disk Utility and password protect that folder, but if seems as if the disk image size is fixed, and therefore you can't add more documents as you go on. I know there a LOT of apps out there that do this, so I have 2 questions.....

1) Is there a free way of doing this?

2) Are there apps that you have used and are happy with?

Thanks

A Sparse disk image should keep changing size as you add to it.

When I try to create an image from a folder, it doesn't give me the option for a sparse disk....



I found it... instead of making an image from folder, just make the image and then dump in the folder

This interests me, but what you are saying doesn't make sense to me. Can you walk thru your steps for me? Appreciate it greatly!

Is this a shared computer?

Why not just create a second account for the other user?

No need to go thru the steps since they cant see your stuff...

Open disk utility... Go to "file" and select New Image -> Blank Image. I then set the parameters... size of 100 GB (make sure I have plenty of room, I've only got about 25 GB of stuff I need to lock up now) and "sparse disk image" and the encryption level.

Worked great.

OK, I did that but it gives me a .dmg and how do I add a folder or other info to a .dmg?

Sorry-ignore that last post-I missed the sparse image. But, I gave it a password, but when I double-click on the sparse image icon, it opens without asking for a password.

DP, you have to add your files, then unmount the image. It only asks for the password when you try to re-open the image.

Yep. Then open it up to re-mount it and it should ask you for the password. Beware that it seems you can delete the unmounted image without using a password.

Boy, what a pain! Why can't there be an option with a new folder to just password protect it?

OK, thx, jard and mike.

Because it wouldn't be secure with just a password. You CAN give a folder permissions so that only your users could see it, but ignoring the ownership on the disk option would negate that as would anyone with an admin or root level account. You need encryption as well as a password. The sparse image provides encryption. The other way to do it would be to use Filevault on your account.

Not free, but Espionage does exactly what you want. I have been using this software for at least 5 years without any hiccups.
