If you don't understand how to operate your own computer then I suspect you may have some difficulties with this project my friend. But ANYWHO....
Do what Skullcandy Girl said, then when a drop down menu (a box, with a list of options, from the mouse) select the "save target as" then save it in a folder on your desktop that is named ("pep EVA stuff"; you will have to make this folder yourself).
OR
Click on the link and it'll prompt you to save it. Continue the above instructions from the "...save in a folder on..." part. ONCE YOU HAVE ALL THE FILES DOWNLOADED: plug in your flash drive and open that folder and DRAG the "pep EVA stuff" folder into it.
VOILA! You now have it all on the flash drive. I don't have a Mac, but I'm pretty sure that that's how it'll go (Macs and PCs keep getting more and more alike these days...)
