The PC I use for FS doesn't have internet access. Is there anyway I can save the files to a disk or something and then transfer them to my FS PC? Please excuse the silly question.
The only way is to use a PC with internet access and download the files then copy them to a CD.
If It's pay ware addons you are looking for then most of them can be ordered on a CD.
There's a magazine you might be able to get in your area "PC Pilot".
The magazine comes with a CD which contains free add-ons.
