I have this big 500mb STEP file that I'm working with for reference for other jobs, it has 1000's of parts in it. I've opened it in solidworks, all ok, and saved it as solidworks file, all ok.
My problem is every 10min it does a 'save auto-recover information' and it stops for 1min to try save it. This is getting annoying. 

Looking at the settings, looks like you can only set 'save auto-recover information
