Can I delete 'dev_hdd1\cache' directory?.

Hi. I need support just to clarify the next question:

It is safe to delete the directory contents of ...\dev_hdd1\cache?. I supose the contents inside are just cache files that will be generated again at some point on the emulation, but I must be aware of that. I just pretend to clean garbage to make smaller the directory size on which I have installed RPCS3, and I thought that maybe those cache files could be deleted without worries...

Thanks in advance for answer my question.
