Just a quick comment here... I have downloaded Alibre
https://www.alibre.com/
...and it is able to load and re-save Solidworks files. One doesn't have to wade through all your Solidworks files and re-save them in another format before your license expires. It does export in other formats, such as .stp.
It's not free... $199, currently on sale for $150...but it has a 30-day trial.
