Copy Files - File Copy mode explanation

Hi All!

 I have searched around and I don't know where to find the answer to this question: What is the difference between the file copy modes of "Standard, SmallFull, and Full" inside the Copy Files plugin?

Thanks!

Well, I'm not quite sure, but I think if you choose full the result iso's size would be bigger.
But according to my experiences there is no need to choose full. Just leave the script's default settings.

I'm pretty surprised nobody knows this one. I know it increases the size... but why? What features or components does it add? Are there certain things like .NET etc (for example) that may work more completely with the full copy?
