How to save the rendered preview in Adobe Premiere when closing?

Question

Adobe Premiere

Adobe Premiere after editing video pieces (imposing effects, changing speed, etc.) can make a small resolution preview for working with it. However, every time you run the program, everything that was rendered last time disappears and you have to do it again. Those. each time the preparatory work increases, because. the finished working material increases.
How to make sure that everything that the program has already rendered is saved for the next time? I couldn't find anything in the settings. There is a lot of space on the disk where the project cache is stored.

Answer 1

PP6? Project settings > Scratch Disk, do video and audio have the same paths?
