Deleting Cache Files

Hello,

I was thinking about deleting my The Sims 4 cache files recently but when I look at instructions how to do it I see that I need to delete everything in my cache folder except FileCache. But the thing is when I go to my cache folder I see no FileCache in there. Only pictures and files that end with .dat. And also how about cachestr folder? Is it safe to delete anything in there? Because I only see spotlight_en-us.package here. Is it safe to delete? And also how about onlinethumbnailcache folder? I play with Online Access Feature on and I always play with internet.

So could answer all these questions and provide me step by step instructions how to delete The Sims 4 cache files? Thank you.

Sincerely

Paulius
