Chances are, what you've DL'ed are disc images. What you'll need to do is get a copy of DiskCopy 6.3.3 from Apple (check to see if you don't already have a copy on your 'puter - you might already). It will read and open a disk image file. Now if it is a stuffed image, you'll need to unstuff first (go and get the newest Stuffit Expander), then run the DiskCopy and load it into a folder in the hard drive image. I ran into a few problems with checksum validation on the disc copy, because I didn't process the thing in the right order. Don't give up if the things don't work out - sometimes they have to be expanded, copied then expanded again!
