    Why encryption is better than typical password protection?

    If I need to access files in an encrypted folder, all I have to do is to provide the correct password. Then the ciphered version is automatically decrypted and I can see the plain version.So how can this be any better than typical password protection? 

    What is tripping me off is that in both cases files are protected by a password. Even encrypted drive displays plain versions of the files once correct password is entered. Shouldn't it display ciphered versions ?

    One way to think about it is like this: the password protection for file access is supposed to control who can access a file or a group of files in a password-protected folder.  But if someone *does* get unauthorized access, let's say by stealing your laptop and booting it off a CD ROM which grants them administrator privileges, well then they would be able to access the files, but because of the encryption, the data would be meaningless.

    Another example - a hacker gets access to your system because of some virus or trojan/back-door.  He might be able to read the file, but if the contents are encrypted, then again, the data will be unintelligible.

    Make sense?
