What is it?

What happens if you delete it?
Premiere renders them again the next time you render the timeline; until then, effect-heavy sections may play back less smoothly. The project and your exports are not affected.
How to remove it properly
With the project open, choose Sequence › Delete Render Files. For old projects, quit Premiere Pro and move the folder to the Trash.
