This is the guide i've been using, but, i don't get this paragraph

After the downloading is finished, what you get will be a compressed application pack named “pandora”, decompress it to the root directory of a hard disc, say Disc H .
In this “pandora” folder, you can see four folders including mspformat, msinst, battery and installer, and a file named UPDATE.PBP.

I don't get the first 2 lines, i have the download complete but not sure what to do with it

just place it in C:/ or whatever your drive letter is. I assume you know how to decompress it.
