In case SW might close in the future, what can I do about my articles I wish to save?

I have written something like 3,227 articles here and I found out that I can't get them all in one bundle and save them from here. They said that they don't have a way to do that here and that really bothers me, because I want them all and I worked so hard on them. I don't know how to get them all into one file. It seems like when I transferred my posts over from EP, I was looking at them and it seemed like the whole article was not there, so that really concerns me and so I asked the staff if I could have all my articles that I wrote here, sent to me and they said they can't do that, but also my EP articles were sent in a zip file and I don't know how to unzip them. I don't understand that technical stuff, but somehow I was able to click on a post I had written and got to read it, but it just didn't seem the same. I just want them sent to me an easy to open format, like esch article would be in pdf form and also have it so that if I wanted to copy my articles, I could also do that from the pdf document , but it looks like I'm going to lose all my articles and that really bothers me, cuz I wanted to make a book of them for myself, so I could hand them down to my daughters and grandchildren. I wish I had a solution. I just can't copy them all one by one, that would take forever. I've always been good with doing everything else on the computer it seems, but I don't like these deals where you have to unzip things and make it more complicated. And then it seems like if they send it to me in a zip file, I have a time trying to get it to open and all that stuff and I just hate it. There has to be a better way.
