HOW TO DELETE SET-UP FILES
You don't need to delete the entire game as you will lose all progress made in career mode etc...
1) select settings icon in PS4 menu
2)scroll down and select Application Saved Data Management
3) select Saved Data In System Storage
4) select Delete
5)select pcars2 icon
6) scroll through list and select all files labeled Tuning Setup
7) you will also see 2 files labeled Profile, select one of those, oldest one if the dates don't match. This is a glitch that just uses up space.
8) select Delete
9) select Ok and you're done
As ps+ users we all have cloud storage available. I would suggest that you back up remaining data.
1) in Application Saved Data Management select Upload To Online Storage
2) select pcars2 icon
3) click Select All on right side of screen
4) select Upload
5) prompt will come up asking Do you Want To Overwrite This Saved Data? select box for Apply To All then select Yes and you're done
Note: during delete process I would also recommend selecting any replay files shown as it will free up system space and you don't really want to take up cloud space with it either as we are limited to how much cloud space we have.
Hope this helps!
