Right. There are two commands you need.
The first,
dir, will show you the contents of the directory you are in.
The second
cd is short for Change Directory
The following is predicated on you having put your files in a directory called C:\Rockbox
Assuming that you are in the C:\ drive you should see
C:\>
If not, then type cd ..
That will take you up a level.
Keep doing this until you see the C:\> prompt
If you now type dir you will see a directory listing like this...

7 File(s) 1,192 bytes
9 Dir(s) 10,483,691,520 bytes free
(I have had to edit out some "less than"DIR"more than" things for formatting reasons)
Now type cd Rockbox
and you will see
C:\Rockbox>
Now you can follow on from the instructions....
