Hi experts!
I have 2 questions about 2 strange Folders I saw. Answering each question will have 250 point!

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
1) My friend gave me a multimedia DVD as a gift.
It has a hidden directory on it. It's not a normal hidden folder. (not having system attributes or hidden attributes)
My both folder option items for showing files are unchecked.
When working with the DVD files I found out that all of the files on the DVD are about 400 MB in size. But the DVD used size was 3.8GB.
I recognized it when I was used Isobuster. There were two sections which one of them contained that data folder and the other didn't.
The two sections as I've always seen must be the same.
I think one of them is the one shown to the user and one of them is the one that contains real files and folders.
The name of one of the sections was "ISO" and the other was ">>>>".
Anyone knows what's the trick?
I want to know how to create such a folder!
It's very useful.

2) I have a flash memory security software that creates a non-deletable folder called autorun.inf!
this autorun.inf folder prevents viruses to write their own inf file to the disk! A nice idea!
But how it works is important:
inside the autorun.inf folder exist a directory called"immunity." and can not be modified in anyway.
When I want to enter it I see the below error. (See the attached file)
It seems to be some kind of shortcut! (but not a regular one)
I want to know how to create such a folder too!
