Help with "root" and "VSHELL"

[brash]

Okay, I have two questions, and I need someone to answer them for me, because I'm totally lost.

1) I need to copy two files into the "root" of my flash card, but I don't know what the root is. I assume is the first area in the flash card when transferring data (so the first folder once I click the "removable e drive"), but I'm not sure.

2) I need to "enter in the VSHELL" to launch the version changer. To me that means "shoot yourself in the head trying to figure this out".
I have no idea what VSHELL is, nor do I know how to "enter it in".

Anyone who could explain this stuff would be a great help.
Thanks.

Oh, and one last thing while I'm on this subject. Once you downgrade, is it possible to get rid of the dowgrade if you don't want it, or are you stuck with it?

The "root" is what you see when you double-click "Removable Disk".

"VSHELL" is a fancy word for the PSP's menu. That's all it is.

I hope I help.
