I hope that you won't be concerned about large file sizes:

If you have a CD or DVD player, you can download a presentation to your computer, then burn it to a disc, and if your disc plays in your CD or DVD player, you can, if you wish, delete the file from your computer;
If you don't have any external CD or DVD player that plays discs that you burn, most discs that you burn on your computer can be played on your computer;
If your hard drive is large enough, you can leave the downloaded files on your hard drive and play the files from there.
