    This is useful for some situations, but I’m looking to password protect a folder that I can then add things to or modify the contents of the folder. Using the disk image method I’d have to make a new disk image every single time I modify the contents.

    Good idea but should you not uncheck the “Remember password in my keychain” box because that can be read.
