But I can’t download them on my software
Why not? What is it about your “software” that prevents you from being able to download them?
The only computer I have is a horrible chromebook. It’s really only good for email.
That shouldn’t be a problem as long as you have an Internet connection and a large enough hard drive (which can be an external USB hard drive), right? Granted, I know next to nothing about Chromebooks, so maybe something else about them precludes being able to download large files…
