Funny that you posted this today, Last Thursday I realized that I had not done all my yearly downloads and realized that in fact I had only downloaded about 10 of the proceedings and was worried that they might be gone.
I used my old link and I was happy to see that the proceedings are still there for SWW2018. I also found the proceedings for 2017 are also still there. I finished downloading all the Presentation power point presentations last week and am almost finished downloading the video's ( I do this yearly).
I was going to find this thread and post to it that the SWW2018 Proceedings were still available (after I finished downloading what I wanted).
Try this link for 2018 (you will have to create an account if you have not already done this and you will have to login - https://solidworksworld.lanyonevents.com/2018/connect/search.ww
The same is true for SWW2017 proceedings - must have a different login name and password for 2017.
try using the above link but change the 2018 to 2017 and see if it works for last years (2017)
Forgot to add to my last post, all the proceedings prior to 2017 are no longer available online.
I was surprised to see that the 2017 site was still there now - Rachel York must have convinced some people to leave them up for a while - Hope they stay up for several years.
It would be nice if they could restore the old ones that are no longer posted.
I suggest you download what you want (or whatever you think you would possibly want in the future) in case they go away.at some time.
I have most from 2010 to now (but missing some individual files) But it takes a lot of space to store those.
The newer videos are also higher quality / resolution and much bigger in size - most are about 1 gig in size - some over 2 gig.
The old ones from years ago were closer to 200 meg.
